Play Online: Refraction
Split and bend lasers to save animals who have gotten stuck in space!
Refraction is a puzzle game originally built for teaching fractions, although it has been popular with adults as well. The player must partition lasers in order to power spaceships containing various animals who have gotten stuck in space. These animal spaceships all require different fractions of the lasers, and the player is given several pieces that split and bend the lasers to reach the animals and satisfy these requirements. These mechanics can be used to teach many important fraction concepts, such as equal partitioning, addition, multiplication, mixed numbers, improper fractions, and common denominators.
Refraction won the Grand Prize at the Disney Learning Challenge at SIGGRAPH 2010.
