Boosting math skills is a blast—with fun folder games children play on their own! Each ready-to-use game targets key math standards…and comes with everything students need for independent practice. Children simply grab a color-coded folder and corresponding pouch of tiles…follow the simple, 3-step instructions to complete the activity…then check their own answers for instant reinforcement! Complete set includes all 4 libraries shown, each with 10 games in a storage box—for a total of 40 games. Folders measure 9 1/4" x 11 5/8". Each library also available separately below.
