Pupils needing extra support
Should take the ‘fetch’ role in the drawing activity; should use the skill level one image from the Resource: Fetch-Decode-Execute pictures; could be provided with a printed version of the NASA video transcripts (which can be found below the videos); could be provided with the Resource: The Fetch-Decode-Execute cycle.
Pupils working at greater depth
