- What shapes was it made up of?

- How many squares do you think there were?
You may now want to look at the diagram again. Do you notice things that you didn't see before?

Key questions
Possible extension
Learners could create their own diagram for others to try in the same way.
Possible support
It may be useful for some children to have copies of the diagrams on this sheet. Some learners may find it very difficult to picture the diagram in their 'mind's eye' so you could suggest they copy the picture instead.
