Dr Mike's Math Games for Kids has over 90 free math games and worksheets to help parents and teachers help kids enjoy math. These range from plain vanilla worksheets to online arcade-style games - from kindy counting games to really tough open-ended puzzles. There are games related to arithmetic, geometry, fractions, powers, as well as puzzles that help general thinking skills. There are even some that hide advanced math topics such as number theory just below the surface of a simple game!

With so many games to choose form, it can be hard to find the one you want. I've tried to sort them into various lists - you can access some of these from the menus at the right - but there'll always be one or two that slip through the cracks. That's why I've made this 'sitemap' page, listing every single game on the site! Scroll down, explore and enjoy!
