Mastered your subtraction facts? Move beyond the basics and build numeracy with twenty-two levels of subtraction problems using 0 -100. Beginning levels review counting down by 2s, 5s, and 10s. Later levels quickly kick it up a notch with double-digit minuends and regrouping (borrowing). The highest levels mix problems that require regrouping and those that do not — can you choose the right subtraction strategy?

Win Gold each time you pass a level, then spend the Gold to reward yourself with a round of arcade-style game play in Super Dragon Fire. (Look inside the game to find other ways to spend your hard-earned Gold.)

Challenge your friends on Game Center — who can earn the most Gold?
