Plus or Minus is a great game for students who have beginning number sense and are developing addition and subtraction skills. It's also a great way to use checker or chess boards that no longer have pieces to go with them.
The board is divided into two sides. Students take turns rolling a traditional die and a die which we wrote + and - signs on. They add or subtract markers as indicated by their dice rolls. The first one to fill up their side is the winner. You can order dice from Craftpacks. We especially like the foam dice, since they enable children to roll soundlessly.
