What does a student learn in StateAlabama,GradeGrade 11,SubjectMathematics?

Real numbers cover every point on a number line, from simple fractions to never-ending decimals like pi. Complex numbers go further, covering values that real numbers alone cannot reach.

Students simplify and combine radical expressions, such as square roots, using addition, subtraction, multiplication, and division. The goal is to spot the repeating numerical patterns that show up in geometric figures.

Students practice choosing and converting units so their math matches the real world. A speed in miles per hour, a weight in grams, a length in feet: picking the right unit keeps calculations and models accurate.

Students use units like miles, hours, or dollars to make sense of a multi-step problem and check that their answer lands in the right ballpark.

Students pick units that make sense for a formula (miles per hour, square feet, dollars per pound) and make sure those units stay consistent from the first number to the final answer.

Students decide where a graph's number line should start and how far apart the tick marks should be, then explain why those choices make the data easier to read.

Students choose which numbers actually matter for a problem, such as picking speed instead of distance when modeling a commute. The skill is deciding what to measure, not just how to measure it.

Students learn to match their reported answer to the precision their measuring tool actually allows. A ruler that reads to the nearest millimeter, for example, cannot support an answer stated to the nearest tenth of a millimeter.

Students learn to read what an equation is actually asking before deciding how to solve it. For linear and quadratic equations, inequalities, and two-variable systems, they choose a solving method on purpose and explain why their answer works.

Students find where two lines on a graph cross by solving their equations together or reading the intersection off the graph. They repeat this for each pair of lines to locate every corner of a polygon.

Algebra lets students write equations and inequalities to model real situations, like predicting costs or population growth. They work with linear, quadratic, and exponential patterns to analyze data and make predictions.

Students learn to rewrite a formula so a specific variable stands alone on one side, the way they'd solve for x in an equation. If a formula gives area, they can rearrange it to solve for length instead.

Students use graphs to solve equations and inequalities, reading exact or estimated answers directly from a plotted line or curve. This includes finding where two lines cross or where a line meets a curved path.

Students check that every point on a straight-line graph is a solution to the equation, and that every solution lands on that same line. The graph and the equation are two ways of showing the same relationship.

Students use the Pythagorean Theorem to build the equation of a circle from its center point and radius. It shows why every point on a circle sits exactly the same distance from the center.

Students find the center of a circle by locating the midpoint between two given endpoints, then use the Pythagorean Theorem to write the circle's equation.

Students use the Pythagorean Theorem to build the formula for measuring the straight-line distance between any two points on a graph. It connects geometry to coordinate math in one step.

Students learn to look at data critically, spot weak conclusions, and judge whether a risk is worth taking. This is the thinking behind headlines, studies, and everyday decisions.

Students read graphs and data tables to spot patterns, then use those patterns to draw conclusions and judge how likely something is to go wrong or work out.

Numbers and categories are two different kinds of data, and real data often needs sorting and cleaning before it means anything. Students learn to recognize which type they're working with and how to organize messy data sets so analysis can actually begin.

Students use spreadsheets or software to sort and organize large sets of numbers so the data is easier to read and work with.

Students learn to read a set of data and describe its shape, typical middle value, and spread, including how spread out the numbers are using standard deviation. They also spot values that fall far outside the pattern and use all of this to compare two groups side by side.

Students pick the right type of chart (dot plot, histogram, box plot, or scatter plot) to display a set of numbers, then build it by hand for small data sets and with a calculator or software for larger ones.

Students compare two or more data sets by looking at where each group clusters (mean or median) and how spread out the values are (interquartile range or standard deviation). The shape of the data determines which measure fits best.

Standard deviation is a more precise version of mean absolute deviation. Students learn how both measure how spread out a set of data is, and why squaring the differences (instead of ignoring their sign) gives a more useful picture of that spread.

Students calculate how spread out the numbers in a data set are from the average. This measure, called standard deviation, shows whether the values cluster tightly together or scatter widely.

Students compare two or more data sets by looking at their shape, center, and spread, then decide whether an unusually high or low value is skewing the average or making the data look more spread out than it really is.

Scatter plots show how two real-world things relate by plotting them as dots on a graph. Students read the pattern those dots make to spot trends, clusters, or gaps in the data.

Students plot two sets of numbers on a graph to see if they move together. For example, they might chart height and shoe size to find out whether taller people tend to wear bigger shoes.

Students draw a best-fit line through a scatter plot, then check how far off each prediction is by measuring the gaps between the line and the actual data points. Adjusting the line to shrink those gaps makes the prediction more accurate.

Students use a calculator or software to draw the line that fits a scatter plot as closely as possible, then use that line to spot trends between two sets of numbers.

Students learn to draw a line of best fit through a scatterplot, check how well it matches the data, and calculate how strongly two quantities are related. They also learn why a strong pattern in data does not prove one thing causes the other.

Students use a calculator or software to find a number between -1 and 1 that measures how closely two things are related on a graph. A result near 1 or -1 means a strong relationship; a result near 0 means little to none.

Correlation means two things tend to move together. Causation means one thing actually causes the other. Students learn why spotting a pattern in data does not prove that one factor is responsible for the change.

Students learn to read real data, build a model that fits the situation, and use it to make decisions or predictions. The work connects math to problems worth solving.

Students build a straight-line equation from real data, such as temperature over time or price versus quantity, then use it to predict values the data did not show.

Students use a line drawn through a scatterplot to make predictions about real-world situations, such as estimating future sales or expected test scores based on a trend in the data.

Students read a graph's trend line and explain what the steepness and starting point actually mean for the real situation, such as how fast a price rises or what the value was at day zero.

Students figure out the area or volume of a complex shape by mentally cutting it into simpler pieces, like rectangles or triangles, then adding those pieces back together.

Slice a 3D shape like a cone or cylinder and name the flat shape you see in the cut. Students also figure out what 3D shape spinning a flat figure around an axis would create.

Students calculate surface area and volume for 3D shapes, including shapes made by combining two solids or cutting a piece out of one. Think of a box with a cylinder drilled through it.

Students explain why the volume and surface area formulas for spheres, cylinders, pyramids, and cones actually work, not just how to use them. They use visual reasoning and comparisons between shapes to build the argument.

Students use geometry formulas to find an unknown length, width, or height when the surface area or volume of a shape is already known. They work backward from the answer to find the missing measurement.

Students practice estimating measurements using tools like rulers, calculators, and apps to build a clearer sense of how measurement actually works. Getting close to the right answer first helps make the exact answer meaningful.

Students find the perimeter and area of a shape when only its corner coordinates are given, using formulas or geometry tools, then check whether the answer makes sense.

Two shapes are similar when one is a scaled version of the other. Students use that ratio to find a missing length, area, or volume on the larger or smaller shape without measuring it directly.

Students learn how scaling a shape up or down affects its perimeter, area, and volume by predictable amounts. If a shape doubles in size, its perimeter doubles, its area quadruples, and its volume multiplies by eight.

Students learn where the arc length and sector area formulas come from, then use them to solve problems. Both formulas scale a circle's full circumference or area by the fraction of the circle the angle cuts out.

Students learn how sliding, flipping, or rotating a shape changes its position without changing its size or angles. They also explore which shapes look identical before and after a move, which is how symmetry works.

Students use graph paper or geometry software to draw, move, and combine shape transformations, such as slides, flips, and turns, to show how a figure changes position or orientation on a flat surface.

Students describe how moves like slides, flips, and rotations work as rules that take a point's location and produce a new location. They write those rules in plain language and in function notation.

Students sort geometric transformations into two groups: those that keep shapes the same size and angle, like slides and flips, and those that stretch or shrink them. The goal is recognizing what changes and what stays the same.

Students practice moving, flipping, and rotating shapes on a coordinate grid, using graph paper or software to see exactly how each transformation changes a shape's position without changing its size.

Students draw a shape after it has been slid, flipped, or turned, using graph paper or geometry software to place the new shape correctly.

Students describe the exact steps (rotate, flip, or slide) needed to move one shape so it lands perfectly on top of another.

Students draw shapes that have line symmetry, rotational symmetry, or both, then describe what makes each type distinct.

Rotation, reflection, and translation are the three ways to move a shape without changing its size. Students define each move using angles, parallel lines, and other geometric relationships.

Two shapes are congruent if you can slide, flip, or rotate one until it lines up exactly with the other. Students prove congruence by identifying the specific moves that get one figure to land perfectly on top of the other.

Two shapes are congruent if you can slide, spin, or flip one until it lands exactly on the other. Students identify the specific moves that map one shape onto its match.

Students prove two triangles are identical in size and shape by sliding, flipping, or rotating one until it lines up exactly with the other.

Two triangles are congruent when every matching side and every matching angle are equal in size. Students check this by comparing each pair of sides and angles across both triangles.

Students use measurements of angles and sides to prove two triangles are identical in size and shape. They apply four shortcut rules (SSS, SAS, ASA, AAS) that tell you when matching parts are enough to confirm a perfect match.

Students prove two shapes are similar by finding the resize, flip, slide, or turn that maps one onto the other. If one shape is a scaled-up or scaled-down version of another, a single dilation or a short sequence of moves connects them.

Students test what happens to a shape when it's enlarged or shrunk from a fixed point. They check that the new shape stays the same proportions as the original, just bigger or smaller.

Students zoom a figure in or out from a fixed center point and check what happens to nearby lines. Lines that miss the center shift outward but stay parallel; lines that run through the center don't move at all.

Students scale a line segment up or down using a given ratio, then confirm the new length matches what the math predicts. If the scale factor is 3, the image should be exactly three times as long.

Students decide if two shapes are similar by finding the combination of slides, flips, turns, and size changes that maps one shape exactly onto the other.

Students prove two triangles are similar by finding the exact combination of slides, flips, rotations, and size changes that maps one triangle perfectly onto the other.

Students check whether two triangles are truly similar by confirming that their matching angles are equal and their matching sides scale up or down by the same ratio.

Students check whether two triangles are the same shape but different sizes by comparing their angles and side lengths. Two matching angles, two proportional sides with the angle between them, or all three sides in proportion each confirm the triangles are similar.

Students use digital tools to build geometric shapes under set rules, then test whether changing one part of a figure forces other parts to change. This reveals which properties are truly connected and which are independent.

Students look for patterns across shapes like triangles, rectangles, and circles, using rulers, graphing tools, or software to spot what stays the same and what changes between figures.

Students use drawing tools or geometry software to build shapes, then test their hunches about how those shapes behave. The goal is to notice patterns and check whether they hold up.

Students learn which measurements and rules are the minimum needed to draw a specific shape accurately. Given a triangle or quadrilateral, they decide which properties, like side lengths or angles, are enough to pin it down.

Students learn to prove whether a geometric statement is true or false and write that proof in a clear, logical argument. The format can vary: a two-column layout, a paragraph, or another organized structure that shows each step.

Students learn the exact definitions of basic shapes and lines: what makes lines parallel, what defines a circle, and how angles and segments are measured. These precise definitions are the foundation for every geometry proof and problem that follows.

Students decide whether a geometry rule is true or false, write out the reasoning that proves it, and then use that proven rule to solve problems. Proofs can be written as a paragraph, a two-column chart, or a flow diagram.

When two straight lines cross, students prove why certain angle pairs must be equal. They also show why cutting across parallel lines creates matching angles, and why the midpoint line of a segment stays perfectly centered between its two endpoints.

The three inside angles of any triangle always add up to 180 degrees. Students also prove rules about equal sides, midpoints, parallel lines, and the Pythagorean Theorem, then use those rules to solve real geometry problems.

Students prove why four-sided shapes like rectangles, rhombuses, and trapezoids follow specific rules, such as when opposite sides must be equal or parallel, and how those shapes relate to one another.

Geometry proofs can use different methods: moving shapes around, plotting points on a grid, or writing equations. Students learn that no single method works best every time, and switching approaches can make a hard proof click.

Students use x-y coordinates on a graph to prove geometric facts, like showing two sides of a shape are equal or that two lines are perpendicular, using algebra instead of a ruler.

Students prove why parallel lines have equal slopes and perpendicular lines have slopes that are negative reciprocals, then use those rules to solve geometry problems on a coordinate grid.

Students spot geometric relationships in everyday objects and situations, like using right triangle ratios to find a building's height or checking whether two shapes are identical. Recognizing those connections turns geometry into a practical problem-solving tool.

Students apply triangle rules to real-world problems, using what they know about matching or scaled triangles to find missing measurements like distances or heights they can't measure directly.

Students use the proportions inside similar right triangles to find missing side lengths and angles. If two right triangles share the same shape but different sizes, the ratios between their sides stay the same.

Special right triangles have side lengths that always stay in the same ratio. Students learn those fixed ratios for 45-45-90 and 30-60-90 triangles, then use them to find missing side lengths without measuring.

Students use the proportions inside similar triangles to define the three core trig ratios: sine, cosine, and tangent. Each ratio compares two sides of a right triangle relative to one of its angles.

Students learn that the sine of any angle equals the cosine of its complement, and vice versa. So sin(30°) and cos(60°) are always the same value, because 30 and 60 add up to 90 degrees.

Students use side lengths to prove whether a triangle is a right triangle. If the three sides satisfy a² + b² = c², the triangle has a right angle.

Students use sine, cosine, and the Pythagorean Theorem to find missing side lengths and angles in right triangles, then apply those skills to real problems like calculating the area of a hexagon or the height of a ramp.

Students use shapes like circles, rectangles, and triangles to represent real objects, then use measurements and properties of those shapes to solve practical problems.

Students study the hidden rules that govern circles: why an angle drawn from the center differs from one drawn on the edge, why a triangle tucked inside a semicircle always has a right angle, and why a radius meets a tangent line at exactly 90 degrees.

Students work through real-world problems using geometry: they simplify a messy situation, solve it with geometric tools, then check whether their answer actually makes sense in the real world.

Students apply geometry to real design problems, working through a full cycle of planning, modeling, and checking their solution. This might mean using area, scale, or shape to figure out whether a design actually works.

Rational numbers (like fractions and repeating decimals) and irrational numbers (like the square root of 2) together cover every point on the number line. Beyond those sits another category, complex numbers, which include values no point on the number line can represent.

Rational exponents are a shorthand for roots. Students learn why writing 8 to the power of 1/3 means the same thing as the cube root of 8, connecting the rules they already know for whole-number exponents to this new notation.

Students rewrite square roots and cube roots as fractional exponents, and flip between the two forms using basic exponent rules. This skill shows up whenever students simplify or rearrange expressions in algebra.

Students learn that mathematicians invented a number called *i* to handle square roots of negative numbers. It follows one rule: multiply *i* by itself and you get -1.

Rewriting an expression means rearranging it into an equivalent form that shows something useful, like a hidden factor or a simpler structure. Students use rules for addition, multiplication, and exponents to make those features visible without changing the value.

Students look at a math expression and figure out what each part means in real life. For example, in a formula about money growing over time, they treat a chunk of the expression as one meaningful piece instead of breaking it into separate operations.

Students look at an expression like x² - 9 and spot that it can be rewritten as (x+3)(x-3). Recognizing the shape of an expression helps students simplify or factor it without starting from scratch.

Students rewrite an expression, such as a quadratic or exponential, into a different form to make a hidden property visible, like seeing the maximum value of a parabola or the growth rate of an investment.

Students rewrite a quadratic expression like x² + 5x + 6 into two multiplied parentheses, then use that form to find where the graph crosses the x-axis.

Rewriting a quadratic equation in vertex form shows where a parabola peaks or bottoms out and what line splits it in half. Students also practice completing the square to get there when the equation starts with x².

Students rewrite exponential expressions using exponent rules, such as turning 2 to the 3x power into 8 to the x power. This shows two equations that look different actually describe the same function.

Students add, subtract, and multiply polynomial expressions, noticing that the result is always another polynomial. The math stays inside the same family of expressions, the way adding two whole numbers always gives back a whole number.

Solving an equation or inequality isn't just finding an answer. Students check every candidate solution to confirm it actually works, catching answers that look right on paper but break the original problem.

Solving an equation with absolute values can produce answers that look right but fail when plugged back in. Students learn why that happens and how to check each answer against the original equation.

Students look at an equation or inequality, figure out the most straightforward way to solve it, and then explain why their answer is correct. This applies to linear equations, quadratic equations, and systems with two variables.

Students choose the best method to solve a quadratic equation, whether that means factoring, using the quadratic formula, or completing the square. The goal is picking the approach that fits the equation, not just defaulting to one method every time.

Students rewrite any quadratic equation by completing the square, which turns it into a simpler form they can solve directly. Then they use that same process to show where the quadratic formula comes from.

Students practice several methods for solving equations where a variable is squared, choosing the right approach based on how the equation is written. They also learn that some equations produce no real-number answer.

Students choose the best method (graphing, substitution, or elimination) to find where two linear equations meet. The skill is knowing which approach fits the problem, not just grinding through one method every time.

Students solve two equations at once by adding or subtracting them to cancel out one variable. They also learn when that approach is faster than plugging one equation into the other.

Students solve the same pair of equations three ways: by working through the algebra, by plotting lines on a graph, and by checking a table of values. Then they compare what each method shows and explain why all three land on the same answer.

Students use equations and inequalities to analyze patterns and make predictions in real situations, such as figuring out when two phone plans cost the same or how a population grows over time.

Students write an equation or inequality with one unknown to match a real situation, then solve it. The skill covers linear, quadratic, exponential, and absolute value relationships.

Students write equations that connect two changing quantities, like time and cost, then graph those equations to spot patterns and make predictions. Covers straight lines, curves, and other common shapes.

Students write equations or inequalities to describe real-world limits, such as a budget or a time restriction, then solve to find which answers actually work in that situation.

Students learn to think of a function not as a list of individual input-output pairs but as a single object with its own patterns and behavior. That shift makes it easier to analyze and compare relationships between two quantities.

An equation in two variables has infinitely many solutions. When students plot those solutions in the coordinate plane, the pattern they form is the graph of that equation.

A function is a rule that matches each input to exactly one output. Students learn to tell whether a relationship qualifies as a function by checking that no input points to two different outputs.

Students read and write functions using notation like f(x), plug in a value to find the output, and explain what that output means in a real situation, like the cost of buying a certain number of items.

The domain is the set of input values a function will accept. Students read a graph to identify which x-values make sense for a linear, quadratic, exponential, or absolute value function, and explain why certain values are excluded.

Students look at equations, graphs, and tables to decide whether a relationship is a function. A function has exactly one output for every input, written as y = f(x).

Students mix and match linear, quadratic, exponential, and absolute value functions to build new ones that model real situations. They write, calculate, and explain what the combined function means in context.

Students add, subtract, multiply, or divide standard functions like linear and quadratic expressions to build new functions and calculate their output for a given input.

Students combine two functions by plugging one into the other, then evaluate the result for a given input. For example, they might feed a linear function into a quadratic one to model a real situation.

Students use graphs to find exact or approximate solutions to equations and inequalities, including pairs of linear equations and mixed linear-quadratic systems. Reading the graph replaces (or checks) the algebra.

Students find where a line and a curve (or two lines) cross on a graph, reading off the x and y values where the equations share the same point. Graphing tools like Desmos are fair game.

Students explain why the x-values where two graphed lines or curves cross are the solutions to an equation. Reading a graph and solving algebra lead to the same answer, and this standard asks students to say why.

Students find where two graphed lines or curves cross by reading a graph, scanning a table of values, or zooming in with a calculator until the answer gets close enough.

Students graph a linear inequality by shading the region of a coordinate plane where the solutions live. When two inequalities are combined, students shade both and identify where the shaded regions overlap.

Functions show the same relationship between inputs and outputs, and students read and use that relationship written as an equation like f(x) = x², a table, a graph, or a diagram. All four forms describe the same rule.

Students compare two functions shown in different forms, such as an equation alongside a graph or a table alongside a written description, to figure out which grows faster, peaks higher, or behaves differently.

Sequences are patterns of numbers that follow a rule. Students learn to treat each sequence as a function where the position (1st, 2nd, 3rd) determines the value, including rules where each new term depends on the one before it.

Students write two types of rules for number patterns: one that jumps straight to any term, and one that builds each term from the one before it. They connect those rules to linear and exponential equations they already know.

Functions in the same family share the same basic shape and structure. Students learn to recognize these shared patterns so they can identify a function type from its equation or graph.

Students learn how adding a number to a function or multiplying it by a number shifts, stretches, or flips its graph. They also work backward from two graphs to figure out what change was made.

Students look at real-world patterns and decide whether the numbers grow by adding the same amount each time or by multiplying. A steady climb points to a linear model; repeated doubling or halving points to an exponential one.

Linear functions add the same amount over every equal stretch of time or distance. Exponential functions multiply by the same factor instead. Students prove both patterns using tables and equations.

Students identify situations where one quantity grows or shrinks at a steady rate and write a linear function to model them. Think of a car traveling at a constant speed or a savings account adding the same amount each month.

Students learn that when something grows or shrinks by the same percentage over and over (interest on a savings account, a population doubling each year), that pattern is an exponential function. They write an equation to model it.

Students build a linear or exponential equation from a graph, a written description, or two points from a table. They practice recognizing whether a pattern grows by adding the same amount each time or by multiplying.

Students compare graphs of exponential, linear, and quadratic functions to see that exponential growth eventually outpaces the others, no matter how slowly it starts.

Students read the numbers inside a function's equation and explain what they mean in a real situation. For a savings account growing over time, for example, students identify the starting amount, the growth rate, and what the graph's high points and crossings tell you.

Students read a graph or table and explain what the highest point, lowest point, or change in direction means for the real situation it represents. This extends from straight-line patterns to curves, U-shapes, and graphs that bend or shift.

Students find how fast a function's output changes over a chosen interval, like calculating the average speed of a car between two time stamps. They do this by reading an equation, a table, or a graph.

Students graph equations by hand and with a calculator, then label the key features: where the line or curve crosses the axes, where it peaks or bottoms out, and whether it rises or falls over time.

Students graph straight lines and U-shaped curves on a coordinate plane, then label where each graph crosses the axes and where it peaks or bottoms out.

Students graph functions that change rules at different points, like a parking rate that jumps after the first hour. This includes V-shaped absolute value graphs and step functions that jump between flat levels.

Students graph exponential functions on a coordinate plane, marking where the curve crosses the axes and describing what happens to the line as it moves far left or far right.

Students use functions to model real situations, like predicting costs or tracking distance over time. They practice adjusting assumptions, assigning variables, and solving problems grounded in everyday contexts.

Students apply math models to real-world situations, choosing the right type of equation (linear, quadratic, or exponential) to fit the problem, solve it, and check whether the answer actually makes sense.

Students use data and basic probability to decide whether a conclusion holds up and whether a risk is worth taking. Think of it as the math behind deciding if a coin is actually fair or if a health claim is backed by real numbers.

Students look at two yes/no or category-based traits collected together, such as smoking habits and health outcomes, then use the numbers to decide whether a connection is real and how much risk it actually implies.

Students look at real data, decide what it means, and explain why their conclusion makes sense. This standard is about building the habit of using numbers to back up a claim rather than just guessing.

Students pick two real-world categories, collect data, and look for a pattern between them. Then they write an argument explaining what the data shows and why it matters.

Numbers and words collected from the real world fall into two buckets: things you measure or count (like height or test scores) and things you sort into groups (like favorite color or grade level). Students learn to organize raw data so it's ready to analyze.

Quantitative data uses numbers you can measure or count, like test scores or heights. Categorical data sorts things into groups, like favorite colors or yes/no answers. Students learn which type of data calls for which analysis method.

Two-way tables and segmented bar graphs show whether two categories are related. Students read and build these displays to spot patterns, like whether students who study more also tend to score higher.

Students look at two categories of data, like gender and favorite sport, to figure out whether one tends to go along with the other. They use tables or graphs to decide if a real pattern exists or if the two categories seem unrelated.

Students sort data into a two-way table that crosses two categories, such as grade level and favorite sport, then display the results as a bar graph where each bar is divided into segments showing the breakdown.

Students read a two-way table and figure out what the percentages mean. For example, they can tell whether boys or girls in a survey chose a particular answer more often, looking at the whole group or just one row at a time.

Students look at data sorted into categories and describe patterns they notice, such as whether one group tends to choose or experience something more than another group does.

Students use graphs, tables, and equations to model real situations, then analyze the data to figure out what's likely to happen or what the best solution might be.

Students build a table that sorts real data into two categories at once, like age and favorite sport, then use the table to answer a question or spot a pattern.

Students combine data from multiple groups to look for a pattern between two categories, such as whether students who play sports also tend to get higher grades.

Students learn why a pattern that looks true in grouped data can flip or disappear when the groups are combined. A trend seen overall may reverse when you account for a third factor hidden in the data.

Students decide whether two events are connected or unrelated by checking if one outcome changes the odds of the other. This skill helps make sense of probability calculations that involve more than one event.

Students learn to sort and describe probability outcomes using everyday logic: "this or that," "both of these," or "everything except this." It's the math behind organizing what could happen in a random situation.

Students look at a two-way table or tree diagram and decide whether two events affect each other's likelihood. If knowing that one event happened changes the odds of the other, the events are not independent.

Students learn to find the probability of one event given that another event has already happened. They practice reading two-way tables (like survey results sorted by age and opinion) to calculate those conditional probabilities.

Students find the probability that something happens given that something else already happened. They use a two-way table or tree diagram to work through the numbers.

Students learn what it means for two events to be connected or unrelated. For example, whether it rains today might affect the chance of a picnic, but it has no effect on whether a coin lands heads.

Students figure out how likely one event is when they already know another event happened. For example, if you know it rained, what are the chances the game was cancelled? The answer comes from looking only at the outcomes where rain occurred.

Students learn that every point on a number line has a real number, made up of either rational or irrational numbers. They also meet complex numbers, which go beyond the number line entirely.

Numbers like 3 + 2i look strange at first. Students learn that this form, combining a regular number with a multiple of i (where i squared equals negative one), is called a complex number.

Adding, subtracting, and multiplying complex numbers (numbers that include an imaginary part) the same way students combine or distribute regular numbers. The order and grouping rules that work with whole numbers apply here too.

Students learn to organize data into a grid of rows and columns called a matrix. This makes it easier to compare, track, and work with large amounts of information at once.

Students use a grid of numbers called a matrix to organize and work with data. Think of it as a spreadsheet without the labels, where position tells you what each number means.

Students multiply a matrix (a grid of numbers) by a single number to scale every value inside it up or down. This is the foundation for adjusting data sets and solving real-world problems in physics, economics, and more.

Students add, subtract, and multiply grids of numbers (called matrices) when the grids are the right sizes to work together. It's a way to organize and calculate with large sets of data at once.

Matrices have two special cases that work like 0 and 1 do in regular arithmetic. Students learn how the zero matrix and the identity matrix affect addition and multiplication, and why they behave the same way 0 and 1 do with ordinary numbers.

Students find the "opposite" of a square matrix (one that cancels it out by addition) and the "reciprocal" matrix (one that cancels it out by multiplication). A calculator or software handles the heavy arithmetic.

Students learn when a square matrix can be "undone" by another matrix. If the determinant equals zero, no inverse exists; if it's any other number, the inverse can be found.

Rewriting an expression in a different but equal form reveals patterns that were hard to see before. Students rearrange terms using rules for addition, multiplication, and exponents to make solving or graphing easier.

Factoring breaks a polynomial into simpler pieces so students can quickly find where the function hits zero on a graph. Students practice techniques like grouping and difference of squares to rewrite expressions and solve equations.

Students verify algebraic rules that always hold true, such as the difference of squares, then use those rules to explain patterns in numbers. The focus is on building a logical case, not just checking that the math works out.

Solving equations and inequalities isn't finished until students check their answers. A solution that passes the algebra but fails in the original problem is discarded as extraneous.

Solving radical equations sometimes produces answers that look right but fail when plugged back in. Students learn why those false answers appear and how to check every solution to confirm it actually works.

Students look at the structure of an equation or inequality before solving it, choosing the most efficient method based on what they see. They then explain why their solution is correct.

Students rewrite an equation like 2 raised to some power equals a target number by converting it into a logarithm, then use a calculator to find the exact value of the unknown exponent.

Algebra uses expressions, equations, and inequalities to spot patterns and make predictions. Students apply these tools to real situations involving steady growth, curved paths, and rapid change.

Students write equations or inequalities using polynomial, trig, logarithmic, and radical expressions, then solve them to answer real problems. The focus is on function types that go beyond basic linear and quadratic work.

Quadratic equations don't always have clean whole-number answers. Students solve equations where the solutions involve imaginary numbers, written with the letter i, and learn to work with those results the same way they would with any other answer.

Students practice "undoing" equations that involve exponents, square roots, logarithms, and trig functions. To isolate the unknown, students apply the matching inverse operation, the same idea as dividing to undo multiplication, but with more complex functions.

Students write equations that describe how two quantities relate, then graph those equations to spot patterns and make predictions. The work covers a wide range of function types, from polynomials and logarithms to sine, cosine, and radical expressions.

Reading a graph to find where two equations meet gives the answer to a system of equations. Students use graphs to solve problems that would be hard to crack with algebra alone, including lines paired with curves.

Where two lines or curves cross on a graph, the x-value at that crossing point is the answer to the equation where both formulas are set equal. Students explain why that connection is true, not just find the point.

Students find where two graphs cross or where a function hits a target value, using a graphing tool, a table, or repeated closer guesses. The functions involved can be polynomials, sine and cosine curves, logarithms, or other complex shapes.

Functions show the same relationship between inputs and outputs, just displayed different ways. Students read and connect those different forms, such as a table of values, a graph, and an equation, so they can work with whichever one a problem gives them.

Students compare two functions shown in different forms, such as an equation, a graph, or a table, and explain what the differences mean. Functions covered include polynomials, sine and cosine curves, logarithms, and others.

Functions in the same family share a recognizable shape and structure. Students learn to spot those shared traits across different equations and graphs, so they can predict how a function will behave before they work through every detail.

Students learn how changing a number inside or outside a function formula shifts, stretches, or flips its graph. They practice spotting those changes on a graph and working backward to find the exact number that caused them.

A graph of a function tells the same story as its equation, just drawn out. Students read both versions and connect what they see on the graph, like peaks, dips, and crossing points, to what the symbols in the equation actually mean.

Students read a graph or table and explain what its peaks, valleys, and turning points mean in real life. They also sketch a graph from a written description, working across a wide range of function types including polynomial, trigonometric, logarithmic, and piecewise.

Students read a graph to figure out which input values a function will actually accept, then explain what those limits mean in real-world terms. They practice this with curved, wavy, logarithmic, and broken-rule functions.

Students find how fast a function's output rises or falls across a chosen interval, reading that from an equation, a table, or a graph. This applies to curved and wave-shaped functions, not just straight lines.

Students graph advanced functions, including polynomials, sine and cosine curves, logarithms, and others, then identify key features like peaks, intercepts, and asymptotes. Simple cases are done by hand; more complex ones use graphing technology.

Students graph polynomial functions by hand or with tools, marking where the curve crosses the x-axis and showing which direction the ends of the curve head as x grows large or small.

Students graph sine and cosine curves by hand or on a calculator, marking how tall the wave is, where its middle sits, and how long it takes to repeat one full cycle.

Students graph logarithmic functions by hand or with technology, marking where the curve crosses an axis and describing how it behaves as x grows very large or approaches zero.

Students graph fractions like 1/x, finding the invisible lines the curve approaches but never crosses. Those boundary lines are called asymptotes.

Students graph square root and cube root functions by hand or with tools, plotting key points to show the curve's shape and direction.

Students look at pairs of inverse functions side by side and explain how their graphs mirror each other, noting how key features like intercepts, peaks, and end behavior swap roles when the functions are reversed.

The unit circle is a circle with radius 1 centered at the origin. Students use it to define sine and cosine for any angle, not just angles inside a right triangle, by tracking where a point lands as it travels around the circle.

Students use functions to model real situations, like predicting costs or population growth. They practice adjusting assumptions, assigning variables, and solving problems grounded in the real world.

Students apply math to real-world situations by choosing the right type of function, solving the problem, and checking whether the answer actually makes sense in context.

Students learn to look at data critically, questioning whether a conclusion actually follows from the numbers and whether a risk is as large or small as it sounds.

Students look at data that follows a bell-curve shape to draw conclusions about what's likely or unlikely. They make informal judgments about risk, like whether a test score or measurement falls in a normal range or out on the edges.

Students use real data to make a decision and explain why it holds up. This standard is about thinking critically with numbers, not just calculating them.

Students plan a real experiment or survey around a question they care about, collect the data, and write an argument explaining what they found and why it matters.

Students learn to describe and compare data sets by looking at the overall shape, the typical middle value, how spread out the numbers are, and which values fall unusually far from the rest.

Students read data from a normal (bell-shaped) distribution and use a calculator or software to find the average and spread. From there, they apply a standard rule to estimate what percentage of the population falls within a given range.

Students use a calculator or software to check whether a set of data follows the classic bell curve. They apply the 68-95-99.7 rule to see if the data spreads out the way a normal distribution predicts.

Students use a bell-shaped curve to estimate what percentage of a data set falls within a given range, such as how many test scores land between 70 and 90. They use calculators or tables to find those areas.

Students learn to tell apart three ways researchers collect data: asking people questions (a survey), testing something under controlled conditions (an experiment), or watching what happens without interfering (an observational study).

Students learn when to use a survey, a controlled experiment, or simple observation to answer a question, and why randomly choosing who participates makes the results trustworthy.

Randomly selecting people for a survey helps results represent a whole population. Randomly assigning people to groups in an experiment helps show whether a treatment actually caused a change. These are two different jobs for chance.

A statistic describes a sample; a parameter describes the whole population. Students use data from a random sample to make reasonable guesses about what's true for the larger group.

Picking a random sample lets students draw conclusions about a whole population. Randomly assigning people to groups in an experiment lets students draw conclusions about cause and effect. These two methods answer different questions.

Randomness in how a study is set up determines how far you can trust its conclusions. Students learn why a survey or experiment needs random selection before its results can apply to a broader group.

Students learn why experiments without random assignment can mislead. If researchers let people choose their own groups, hidden differences between those groups, not the treatment itself, may explain the results.

Surveys don't always reflect reality. Students learn how flawed questions, skipped responses, or a poorly chosen group can skew results and why that matters before drawing conclusions from any data.

Students look at a survey and decide whether the results can be trusted. They identify where bias crept in, whether from who was asked, who answered, or how the questions were worded.

Bigger samples give more reliable results. When students collect data from more people or items, the numbers they calculate (like an average) are less likely to swing wildly from one sample to the next.

Larger samples produce more consistent results. Students explore how the number of people surveyed affects how much a statistic, like an average or percentage, is likely to shift from sample to sample.

Students repeatedly pull random samples from a population, then compare what happens to the spread of those sample averages as the sample size grows larger. Bigger samples produce tighter, more predictable results.

Students run repeated random samples, then show that the spread in their results shrinks predictably as sample size grows. Bigger samples produce tighter estimates, and the math behind that pattern is the population's standard deviation divided by the square root of the sample size.

Students learn how taking many samples from the same population reveals a pattern, and that pattern lets you estimate what the whole population looks like. The margin of error describes how much a sample result might differ from the real figure.

Students take the same-size sample from a population over and over, then plot the results to see how a statistic like the mean varies by chance. Early practice is done by hand; later work uses a calculator or software to run hundreds of samples at once.

Students check that when you survey many large groups, the averages of those groups cluster around the true population average and form a bell-shaped curve. This only works reliably when each sample is big enough.

Students check whether 95% of sample averages fall within two standard deviations of the true population average, confirming the pattern holds in real data.

Students calculate a range around a sample mean and use it to estimate where the true population mean likely falls 95% of the time. This is how researchers turn survey results into trustworthy conclusions.

Students compare results from two test groups to figure out whether the difference they see is real or just random chance. They run simple simulations to check if the outcome would happen on its own without any treatment at all.

When two shapes are similar, their lengths, areas, and volumes stay in proportion. Students use that ratio to find a missing measurement on the larger or smaller version without measuring it directly.

Radians are a way to measure angles by comparing the curved arc an angle cuts out to the length of the circle's radius. Students learn that one radian is the angle you get when the arc and the radius are exactly the same length.

Students apply geometry to real situations: spotting similar shapes, using symmetry, and working out distances or angles with right triangle trigonometry. The goal is solving actual problems, not just practicing procedures.

Students pick a sine or cosine equation to describe real-world patterns that repeat, like tides or sound waves, by matching the height of the peaks, how often the cycle repeats, and where the middle of the pattern sits.

Students use a right triangle on the unit circle to show why sin²(θ) + cos²(θ) always equals 1, then apply that relationship to find unknown sine, cosine, or tangent values from a single known ratio.

Students find the area of any triangle using two side lengths and the angle between them. This works even when the angle is larger than 90 degrees, because the formula stretches the usual definition of sine to cover those cases too.

Students use two formulas to find missing side lengths and angles in any triangle, not just right triangles. This builds on basic trig by stretching sine and cosine to work with obtuse angles too.
