TuxMath 2.0.3
Educational math arcade game

Tux, of Math Command is an arcade-style video game for learning mathematics. The game-play mechanic is based loosely on that of the arcade game Missile Command, but with comets falling on igloos, rather than missiles. Like Missile Command, players attempt to protect their igloos, but rather than using a trackball-controlled targeting cross-hair, players solve math problems that label each comet, which causes a laser to destroy it. The game also includes a multiplayer mode and Factor-fraction activity called Factoroids.  screenshot
