Computers, tools, and teamwork
Students learn to pick the right device and program for a task, fix common glitches like a frozen screen, and set norms for working well in pairs and small groups.
What does a student learn in
This is the stretch where students move from clicking around to building things on a computer. Students write simple programs, break a big problem into smaller steps, and fix the bugs when something does not work. They start sorting data and spotting patterns, and they learn how to stay safe and kind online. By spring, students can plan and code a short project, test it, and explain how it works to a classmate.
- Coding basics
- Debugging

Year at a glance
How the year usually goes. Every school and district set their own curriculum, so treat this as a guide, not official pacing.
- 1
- 2
Networks and online safety
Students learn how messages and files travel between computers, why passwords matter, and how to share work safely with classmates and family.
- 3
Working with data
Students gather information, sort it into tables and charts, and look for patterns. They use what they find to back up a claim about something real, like weather or recess habits.
- 4
Algorithms and coding
Students break a problem into smaller steps and write short programs to solve it. They test their code, fix what does not work, and try again until it runs the way they planned.
- 5
Computing in the real world
Students share their projects and talk about how technology affects people. They think about fairness, kindness online, and who gets left out when a tool only works for some users.
Mastery Learning Standards
The required skills a student should display by the end of Grade 4.
Concepts
Concepts
- Grades 3-5
Identify, select, and apply hardware, software
Students figure out which devices and programs fit the job at hand, then work through basic fixes when something stops working.
- Grades 3-5
Explain how computer networks and the Internet enable communication…
Students learn how computers connect to each other through networks, and how those connections make it possible to send messages, share files, and work with others online. They also look at how networks keep data safe while it travels.
- Grades 3-5
Collect, transform, and represent data
Students gather information, organize it, and display it in charts or graphs. Then they look for patterns in that data and use what they find to back up an answer or explain a conclusion.
- Grades 3-5
Design, develop, and analyze algorithms and programs to solve problems…
Students write step-by-step instructions a computer can follow to solve a problem or build something new, then check whether those steps actually work.
- Grades 3-5
Investigate the social, ethical, legal
Students look at how computers, apps, and digital tools affect real people's lives, including questions about fairness, privacy, and who gets access to technology.

Practices
Practices
- Grades 3-5
Foster an inclusive computing culture that values diverse perspectives and…
Students learn to work with classmates who have different backgrounds and ideas, and to make sure everyone feels welcome when using technology together.
- Grades 3-5
Collaborate around computing — divide work, share ideas
Students work with classmates to plan and build a computer project, splitting up tasks and combining everyone's ideas into one finished product.
- Grades 3-5
Identify and define problems that can be solved with computation and decompose…
Students look at a big problem, decide if a computer could help solve it, then break it into smaller steps a program could actually follow.
- Grades 3-5
Use abstractions to simplify complexity, generalise solutions
Students learn to spot patterns in a problem and use those patterns as shortcuts, so the same solution can work across more than one situation instead of starting from scratch each time.
- Grades 3-5
Create computational artifacts — programs, simulations, models — by applying…
Students write programs or build digital projects by trying an idea, testing it, fixing what doesn't work, and trying again. The back-and-forth cycle of building and improving is the actual work, not a detour from it.
- Grades 3-5
Systematically test computational artifacts and refine them based on evidence…
Students test a program or app they built, find what breaks or confuses people, and fix it. The goal is a version that works the way it was meant to and is easy for others to use.
- Grades 3-5
Communicate clearly with appropriate vocabulary, visualizations
Students explain how a program or app works by using the right words, pictures, or examples. They back up what they say with real evidence, not just a guess.

Common Questions
What does computer science look like in grades 3 through 5?
Students learn the basics of how computers, networks, and the internet work. They write simple programs, collect and chart data, and talk about how to stay safe and kind online. Most of the work happens through small projects, not lectures.
How can families support this at home without buying anything?
Talk through everyday tech moments. Ask students how they would describe steps to make a sandwich or pack a backpack, since that is the same thinking behind a program. Look at a chart in the news together and ask what it shows.
Does a student need a computer at home to keep up?
No. Unplugged activities like sorting cards, giving step by step directions, or drawing a flowchart on paper build the same thinking. A library computer once a week is plenty for extra practice.
What should students be able to do with a program by the end of fifth grade?
Students should be able to plan a small project, break it into smaller steps, build it in a block based tool like Scratch, and fix it when it does not work. They should also be able to explain what their program does to someone else.
How should the year be sequenced across these five concept areas?
Start with hardware and basic problem solving in the fall so students share a common vocabulary. Move into algorithms and programming through the middle of the year, then layer in data projects. Save networks, safety, and impact discussions for short units woven throughout.
Which skills usually need the most reteaching?
Decomposition and debugging trip students up the most. They want to write the whole program at once and then guess at fixes. Plan extra time for breaking problems into parts and for testing one change at a time.
How is online safety handled at this age?
Students learn what personal information is, why passwords matter, and how to tell an adult when something online feels wrong. Short conversations at home about what students see and share matter more than any single lesson.
How do group projects work when skill levels are so different?
Assign roles such as planner, coder, tester, and presenter, and rotate them across projects. That way a student who is newer to coding still contributes through design or testing, and stronger coders practice explaining their thinking.
How do I know a student is ready for middle school computer science?
A ready student can describe a problem, plan steps to solve it, build a working project, and talk about what they would change next time. They can also explain a simple chart and name a few rules for being safe and respectful online.
