The new water slide has just opened at Larry’s Leisure and there are lots of visitors who want to try it out. Pupils will help Larry add up how much money has fallen down the slide, find the difference between the amount of money he has found at the bottom of the pool compared to yesterday. Finally, pupils will assist Larry with a customer who needs to be given some change after buying some sweat bands.
