Skill:Addition, subtraction, position and direction

Resources: Number grid per pair of pupils, two dice per pair, counters

Activity: Give each pair of pupils a number grid, two dice and some counters. Pupils take it in turns to throw the two dice. They must then decide if they will add or subtract using the two numbers. If their answer appears on the grid they can cover it with a counter. The first person to cover three numbers in a row (vertically, horizontally or diagonally) is the winner.
