Game
This game gives the students practice using mental strategies for addition and subtraction. The aim of the game is to be the first to reach 50. Make sure that the students are aware that some lily pads and stones are hazards and some are bonuses. The students must then decide whether adding or subtracting the number they have rolled will be of the greatest benefit to them. They should both add and subtract to see which direction would take them to a more favourable lily pad or stone.
Encourage the students to add and subtract the number they throw to and from the number they are on and then move straight to the new number rather than counting on or back along the numbered places. The students do not need to throw the exact number to get to 50.
