Motion Math: Hungry Fish

The folks at Motion Math have done it again! Hungry fish is a beautifully designed app that encourages mastery of basic addition and subtraction math facts and true number sense through a simple yet catchy game. You are given a fish that can only eat certain numbers at certain times. Very young children need only to match the correct number to the number on the fish. In more advanced levels children will need to add numbers together to make sure the fish can eat them (5=1+4, 2+3, 5+0). The most advanced levels include larger numbers, subtraction, negative numbers and a faster pace (-16= -4+-12, -9+-7 etc). If you don’t feed your fish, it gets smaller. If you feed your fish enough it gets bigger and earns life points. Life points bring you special awards such as getting to customize its colors and fins. In summary, hungry fish is a well designed app with imaginative and attractive artwork that will develop a strong number sense and entice many children to practice math skills.
