Chocolate

This NRICH maths problem is an excellent problem for helping youngsters to develop their concepts of fractions

It's not so much to do with arithmetical manipulation of fractions but more to do with youngsters exploring and developing their ideas of fractions. It involves visualising and calculating mentally. Reasoning skills will also be paramount.
