Race to zero
Uses two spinners and a grid board containing numbers 119 to 0. Players take turns to spin both spinners and decide which to use, subtracting the amount from their current position. Players explain where they need to move their counter to and explain their thinking. If their partner agrees, they move the counter to the corresponding position. The aim is to move their counter from 119 to zero.
