SuperMathWorld.com, it is awesome because we let kids actually make video games in a mathematical sandbox! There are a ton of math learning solutions but most of them are pop-up worksheets slapped on top of a game. In SMW the math is integrated so every interaction has a mathematical property. The "making games" part is possible because we expose the editor in WebGL game, because we really want to put kids in control of their experience--nothing helps move a kid's mindset from "math sucks" to "math is fun" like being able to create your own world of math toys. We're in beta, launching June 1 and always looking for collaborators! Reach out if you're a math or physics geek, we can make some pretty neat visualizations/interactions using our engine.
