Do It Again: Understanding Loops Through Repetition

Overview

Students explore how repeating actions can be simplified using loops instead of repeating instructions manually.

Learning Objective
Students understand how loops can repeat instructions efficiently instead of writing them multiple times.

Resources needed

  • No materials required
  • Optional: simple action prompts

Lesson stages

0 / 10 done
  1. 1 Introduce repetition as doing the same action multiple times.
  2. 2 Demonstrate repeating an action (e.g. clap 5 times).
  3. 3 Write instructions with repetition.
  4. 4 Introduce loops as a shortcut (repeat 5 times).
  5. 5 Students create their own repeated actions.
  6. 6 Rewrite them using loops.
  7. 7 Test with a partner.
  8. 8 Discuss efficiency.
  9. 9 Share examples.
  10. 10 Discuss: how do loops save time?

Variations

  • Use movement sequences.
  • Add nested loops.
  • Combine with conditions.
More information

Teach: repeat, loop, again, instruction, efficient. Use frames: 'Repeat… times'.

Use physical actions instead of writing.

Can students recognise repetition? Can they use loops to simplify instructions?

No materials required.

Students may repeat instructions instead of using loops.

Loops are a key concept in programming for efficiency.
