For years, the 24 Game has been the primary math game, even inspiring school and regional competitions. Every card includes two wheels - each printed with two or three numbers - and a target number. Kids race to figure out which wheel's numbers can be multiplied or divided to make the target number. The answer is printed on the back of the card. Each set contains three levels of difficulty, so kids can keep playing once they master the basic facts. A child can also play alone for additional practice.
