In this fun-filled game, the excitement and suspense build with each player’s turn—along with essential subtraction skills! To play, children remove one block at a time from the tower of math, then solve the problem on the block aloud. If they answer correctly, they keep the block…but if they make the tower tumble, they’ll have to start again! At the end of the game, the player with the most blocks wins! Game includes 48 wooden blocks, plus a guide with an answer key and instructions for more ways to play. Blocks measure 3" in length.
