chocolateGeorge and Jim want to buy a chocolate bar.

George needs 2p more and Jim needs 50p more to buy it.

When they put their money together, it is still not enough to pay for the chocolate bar.


How much is the chocolate bar?

Why do this problem?

This problem supports children in calculating with money, while it also requires them to be systematic.

Possible approach

Playing with the problem for a few minutes and thinking about what the minimum price of the chocolate bar could be is a useful starting point. How can pupils convince each other that they have all the solutions? Although simultaneous equations seem to be appropriate they would just get in the way!
