Mental Maths Mindstretchers 7-9

This is an ingenious method for getting children to use their maths skills in a problem solving way. Each book contains 80 number wheels that have to be solved using mental agility and skill. Starting with simple addition and subtraction wheels, children progress on to double number wheels where they have to use multiplication, division and decimals. Children will be practising maths skills without even realising they are doing it as they strive to solve the puzzles.
