Mrs. Price introduced me to a very cool online math game today... Lure of the Labyrinth. If there are any pre-algebra students in your life it would be worth sharing it with them. Mrs. Price's class is registered as a class so I have an account as part of one of her class teams. I've tried a few of the games and they're very well done, the best part is that you don't have to do any formal math to complete the tasks but you do have to think in a very mathy way.

Lure of the Labyrinth is a product of the Learning Games to Go project, funded by a Star Schools grant from the U.S. Department of Education, spearheaded by Maryland Public Television, with game design by the Education Arcade at MIT.
