# The Hundred Chart Game

Materials: Two types of tokens (gems & pawns), hundreds chart
Common Core: 1.NBT.C.4, 1.NBT.C.5, 1.NBT.C.6, C2.NBT.B.5
Add and subtract 10s and 1s to pick up the tokens on the hundreds chart.

#### Why We Love The Hundred Chart Game

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.

#### How to Play

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.
Example Turn
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.
