Add and subtract 10s and 1s to pick up the tokens on the hundreds chart.
This game delivers tons of addition and subtraction practice in a way kids love. More, it makes the ideas of adding and subtracting 10s, 1s, 11s and 9s kinesthetically intuitive: they are just simple movements on a hundreds chart. Not only that, it’s easy to make the game easier or harder to match kids skills.
The game is for 2-4 players. You’ll need one hundreds chart per group, plus one pawn per student. Each student also gets a sheet of paper that determines what moves they can make on their turn. Place 6 – 20 “gems” at random locations on the board–more gems mean a longer game. Player put their pawns wherever they like to start the game. On their turn, players choose a move, and move their pawn accordingly. If players land on a gem, they get to keep it. When all the gems are taken, the game is over, and the player with the most gems wins.
My mover is on 47 and there’s a gem I want on 58.
If I move +11, I’ll move to 58 and take the gem.
