In our lesson on finding the difference between a positive and a negative number, the children used their knowledge to play a game.
The children were put into pairs—one of the children was positive and moved from left to right, the other child was negative and moved from right to left. Each child started at zero and took turns to score points. These points were used to move left (negative) or right (positive). The first child to reach their total was the winner!
The task was differentiated so that each pairing could decide the way that they scored points and the total they needed to get to:
Hard —rolled two die and multiplied them together. One player needed to reach 50 points and the other needed to reach –50 points
Easy —rolled one dice. One player needed to reach 10 points and the other needed to reach -10 points
