Has anyone actually seen the content behind the front page of the Hey Math! site? Do they really deliver on the promise of:

HeyMath's mission is to be the math Google - to establish a Web-based platform that enables every student and teacher to learn from the "best teacher in the world" for every math concept and to also be able to benchmark themselves against their peers globally.

If this is for real NO ONE should have to pay for it. If it is genuinely a collection of tools collaboratively built by teachers all over the world to deliver the best math education in the world then it should also be freely available all over the world. After all, teachers all over the world built it. Or did they?

Maybe it's just another flashy presentation of drill exercises delivered via computer over the internet. On the other hand if they've found a way to help kids accomodate difficult concepts (like this one is trying to do) then lets all get on board and share the wealth.

If anyone has seen it I'd love to hear your opinion of it.
