Build & Block Addition & Subtraction Game by Wiebe Carlson Ass
Fluency is the goal in this fun drill game. Two board games in one! Spin sums on the addition board or differences on the subtraction board and search for a matching problem. The goal is to claim four spaces in a row and block your opponent from doing the same. Features multiple computations per play, strategic thinking, and a level playing field for beginner and master, all hallmarks of a Power Learning™ game. Encourages fluency in addition to 9 + 9 and in subtraction to 18 - 9. For 2-4 players or teams. by Wiebe Carlson Ass
