"STOP THAT ZOMBIE! is a truly "hands on" approach to working with addition and subtraction, with links to algebra, patterns and problem solving. The basic puzzle is simple: using the numbers 1- 6, distribute them around a triangle so that each side adds up to 9 (thus, trapping the zombie in his cage!) Where it gets really cool is this: you can arrange those same 6 numbers to add up to 10, 11, and 12 on each side. But the fun doesn't end there: you can differentiate this by using the numbers 2 -
