Why do this problem?

would benefit from using real or 'play' coins. Other children might
use strategies related to counting 2's and 5's. More experienced
children could use addition and think in multiples.
Key questions

purchased.

answered. For example:
- Choose what you would buy, then work out the total price.
- Is it possible to spend all the coins?
- What is the maximum number of items that could be bought?
