  • "With younger pupils, it is a good idea to begin with a reminder about square numbers. Also some practice with squares and square roots on a calculator.
    Next, give a simplified 4 digit version of the same problem. The digits 1, 4, 6, 8 work well.
    Now give the 9 digit version as in this starter."
