What better way to learn essential subtraction facts than with hands-on games that are super-fun to play! Our library comes complete with 10 folder games, so up to 10 students can play at once and get plenty of practice subtracting numbers 0 through 10—with no prep work required. Children simply grab a folder and the color-coded pouch of game pieces…follow the illustrated 3-step instructions on the folder to play the game independently…then use the included answer card to check their own work and get all the reinforcement they need to master the math facts!
