For the math teachers out there...

This is a gem. It is a great online interactive math game that can be used with a projector or even an interactive board if you have one.

Not a teacher.... but anything the teachers can use to make learning interesting is a plus. This looks to be a nice tool.

Thanks for posting.

When I was in elementary school we played a game called 24 which played off of a similar idea. Basically there was a square card with four numbers and the operations you were able to use were in the middle, and you had to take the four numbers to get to 24. It was a really fun game and really everyone got into it, even people who weren't that good at math. When I was in fifth grade we had a school wide competition (which was effectively 4th and 5th grade) and I won I got smacked at the district level though

I'm not very good at doing mental math now but I never forget the factors of 24
