Why do this problem?

This activity is excellent for getting pupils to use their knowledge and understanding of numbers and number operations in relation to the number $4$

Possible approach

This is one of the harder problems for KS 2 so presenting it can be straightforward as is written. It would be good to give to pupils who are likely to have a fair degree of success. But, if needed, a gentle way in would be to work as a group at seeing what answeers you get by combining three $4's$ in all the ways known to the pupils.

Key questions

Tell me about the way you are finding answers.

Possible extension

It would be good for the pupils to be able to suggest what next that seems to flow from this activity.

Possible support

Calculators.
