Computer Science · Grades 9–10
Computer Science basics
How a computer stores data, what an algorithm is, and writing your first small programs.
About this study path
Five sessions for Grade 9–10 computer science: number systems, flowcharts and pseudocode, variables and control flow, and debugging. Examples use plain language first, code second.
What you will be able to do
- You can convert between binary and decimal.
- You can describe an algorithm as numbered steps before coding it.
Work through the sessions
- Binary and number systems — Convert in both directions, then check yourself.
- Algorithms and flowcharts — Solve it on paper first.
- Variables and control flow — Sequence, selection and iteration.
- Debugging habits — Read the error, find the line, change one thing.
- Data and privacy — What your apps actually store about you.
