Why I gave it 3 stars.

I gave it three stars because of the ads. My son plays cool math games, and we have really good internet, so it shouldn't lag so much, but for some reason, it does. I don't mind a little lag, but every time a new ad appears it almost freezes my son's computer.

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 ( and other teen-related sites ( and 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.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
