A selection of cards with a shopping addition question on it to solve. The cards can be cut up and then a selection can be stuck into a child's Mathematics book or they can be cut up and children can self select their cards. The prices can be easily edited to aid differentiation for different children and age groups.
Children can be further challenged by working out how much change they would receive from a given coin or asked to design their own cards for a peer to solve.
The cards tie in nicely with the book 'The Queen's Kickers' by Nicholas Allan.
