Pupils needing extra support:

Should be encouraged to write structured instructions when writing the algorithm (e.g. first, Tina draws a rectangle and then moves to a new place); should focus on completing challenge one when remixing the code; should be encouraged to explore and modify; should be shown how to undo/redo any accidental deletes.

Pupils working at greater depth:

Should focus on challenge three when remixing code to apply previous knowledge in a new context (e.g. changing the repeated 2D shape).
