Mathpx is an experiment to help teach kids basic counting and arithmetic in the most natural way possible. Instead of going years memorizing problems without understanding why, Mathpx is designed to make the connection between the problems written on paper to the fundamental concepts behind them.
Mathpx is an HTML5 game written with the Hoopty Javascript game framework.
Mathpx is free and open source because it's main goal is to find a better way to teach math. If you have an idea for new levels or new features, feel free to get in touch, or even better, jump into the code and get involved.
