Math4Fun play online

This project is one attempt for an inspiring free education. Our belief is that "fail and learn" is the best way to grow up. Through this game we hope that any children (within a phone) can enjoy a good education which fit for each.
Implemented feature:
In this version, we focus basically on math and low-grade education, (kindergarten and primary school). The content follows the Common Core Standard, which is applied widely for the USA and widely EU countries.
Despite our attempts, there remain some technical errors. Enjoy the game and please send us your feedback!
