Lesson plan
Recap and recall
Explain to learners that they will practise putting commands in the correct order. Show the Presentation: Face drawing. Ask learners to order the commands to create an algorithm for drawing a smiley face. Working in pairs, ask learners to discuss their answer.

Differentiation
Learners needing support:
- Should use the Resource: Instruction mistakes clues (support) to guide their thinking step by step when searching for errors.
- Could read each command aloud with a partner to check if it makes sense before deciding whether it is correct or needs fixing.
Learners working at a stretch:
- Should explain their methodology for spotting and correcting mistakes during the Main event, justifying why their approach is effective.
- Could create a completely new set of instructions (not using the banana example), deliberately include an error, and then challenge a partner to debug them.
