This fun game was purchased by my friend Wendy from Teacherspayteachers.com. They have so many resources out there available to you and when you buy big bundled packs it's so much fun.
This idea of this game is that you use a white crayon and draw a secret number in the spaces provided. James is working on counting by tens so I drew all the tens on his paper (10, 20, 30, etc). Then you give the paper to your child and they can't see the numbers. Once they begin adding water colors to each space. . . whaa-lah a number appears.
