Your fish is hungry – hungry for numbers!

Motion Math: Hungry Fish is a fun addition and subtraction game for iPad, iPhone, and iPod Touch. The game features a fish who eats numbers plus instant addition – touch two numbers together and they instantly add. Most addition games teach in the form 3 + 4 = __; Hungry Fish challenges players to find, for example, the many different ways to make a 7 (1+6, 2+5, 3+2+2, etc.). There's 18 levels of challenge (for 4-year-olds to adults) and bonuses that let you customize your fish with new colors and fins. It's also a wonderful game to play with your child, your students, nieces, nephews, cousins, and friends.


"Part of the fun comes from adding a visceral component to math."
