Gamers may remember the old House of the Dead games, which came equipped with awesome mid-90s graphics and a handheld gun. That game was converted to the educational cult classic, "Typing of the Dead." Similarly, "Math vs Zombies" allows kids to get rid of the zombies invading their town by taping the answer to the equation placed over the zombies head. As players progress, the problems get harder to keep the game challenging. By making math fun and entertaining, this is a great way for kids to learn while passing the time.
