What's It About?
Launched by a math teacher in 1997, COOLMATH offers info on addition, geometry, and other math concepts for grade-school- to high-school-aged kids. They can check out algebraic property definitions, learn multiplication tricks, or test out the online graphing calculator; separate sections also offer parents and teachers math-related activities and advice. The site also links to several other sites, including a math site for younger kids, coolmath4kids.com, and sites about teen stress management and other topics.
Is It Any Good?
Since 1997, math teacher "Coolmath Karen" has run this award-winning site to spark kids' interest in all things math. The online math dictionary and calculators alone are enough to teach most basic math concepts, including algebra and geometry. In addition to the main sections for math practice, games, a math dictionary, and lesson help, there are also sections for parents (how to help with math homework: crying isn't a good sign) and teachers (tricks for getting kids motivated in the classroom). It also links to a companion site for younger kids (coolmath4kids.com) and other teen-related sites (totallystressedout.com and FinanceFreak.com). If you're a mathphobe or love to play math games or are just stuck on a new math concept in school, you should add COOLMATH.COM as one of your bookmarks.
