Recipient of a Dr. Toy Best Game Award and a Parents' Choice Award, this is the acclaimed crossword-style equation game that engages and challenges students of any skill level. As with the familiar crossword tile game, players arrange their tiles horizontally or vertically on the 20 x 20 grid, but form numerical equations rather than words. Those who incorporate division and fraction tiles or use the board's premium squares receive higher scores. Created by a collegiate mathematics instructor, the game helps students develop their creative thinking skills, master arithmetic concepts, and practice algebraic reasoning in a stress-free and enjoyable setting. The game's 190 tiles include integers 0-9, simple fractions, operation symbols, and equal signs. Comes with four tile racks. For 2-4 players or teams. Ages 8 and up. (2 lbs.)
