Five levels of play challenge students over a wide range of abilities. At level 1 players find sums of two single digit numbers to 'make ten". At level 5 players use any combination of addition, subtraction, multiplication, division, squares, and square roots to make multiples of ten using three single digit numbers! High interest motivates students to advance to the next level.
