Get ready to play with polygons and points on a plane! Pairs of pupils draw grids on a separate piece of paper and then draw an octagon, right triangle, and a hexagon. They call out points to each other and respond with 'hit' or 'miss' if the points land on the figures. Pupils mark hit's on their grid and record the misses, and continue until they have plotted their partner's shapes. Everyone then answers questions for the grid game.
