Motion Math: Hungry Fish is fun addition and subtraction game for iPad, iPhone, and iPod Touch. The game features instant addition – bring two numbers together and they'll merge and add. Most addition apps and worksheets ask problems of the form 3 + 4 = ?; Hungry Fish requires learners to find, for example, the different ways to make a 7 (1+6, 2+5, 3+2+2, etc.). There's 18 difficulties (for 4-year-olds to adults), bonus levels featuring subtraction and negative numbers, and rewards that let you customize your fish with new colors and fins.
