Project — Rock Paper Scissors

Build a complete player-vs-computer game using random choices and decision logic.

60 minutesLive + guided practiceBeginner friendly
01 · LEARNING TARGETS

What students should understand today

  • Random ChoiceUnderstand what it means, where it is used and practise it in a small example.
  • Game RulesUnderstand what it means, where it is used and practise it in a small example.
  • Score TrackingUnderstand what it means, where it is used and practise it in a small example.
  • Replay LoopUnderstand what it means, where it is used and practise it in a small example.
02 · TEACHING NOTES

Core lesson

Start with the idea, not the syntax. Build a complete player-vs-computer game using random choices and decision logic. The instructor should connect the topic to something students already understand, then introduce the exact terms they need for today.

Build in small steps. The teacher first models one example, then students rebuild the same idea with different values so they learn the logic rather than memorising one answer. Pause after each important change and ask students to predict what will happen before running or refreshing the result.

Develop good habits. Students should type the code themselves, run it frequently and read any error message before changing the code. Keep naming, indentation/structure and output clear enough that another student could follow the work.

03 · LIVE BUILD

Rock Paper Scissors with result rules and a running score.

1

Plan the result first: decide what the user/student should see or be able to do at the end.

2

Build the smallest working version using today’s main concepts and test it immediately.

3

Add one improvement at a time and ask students to explain why each line/element is needed.

4

Test with at least two different inputs, screen sizes or scenarios and fix one issue together.

04 · STUDENT CHALLENGE

Independent practice

Add best-of-five logic or a replay loop.

Teacher rule: give hints in steps, but avoid typing the complete answer for the student. The goal is to make them think, try and correct.
05 · END-OF-DAY CHECK

Before moving to the next day

  • I can explain random choice in simple words.
  • I can explain game rules in simple words.
  • I can explain score tracking in simple words.
  • I can complete today’s mini task with only small hints.
Optional 10–15 minute home practice

Rebuild today’s example once without looking at the finished version. Change the names, values, text or design so the result is clearly your own.
