What better way to learn essential math facts than with hands-on games that are super-fun to play! Each library comes complete with 10 folder games, so up to 10 students can play at once—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 because each library focuses on a single operation, students receive all the reinforcement they need to master the math facts! The complete set includes all 4 libraries shown (40 games total); each folder measures 9 1/4" x 11 5/8". Each library also available separately.Additional Information
