I have, who has?

We've been having lot of fun playing this game in our class over the last week or so. As requested by the boys and girls, I'm posting the game here. 

The kids will be able to explain to you how it's played. It's really helped the boys and girls develop their mental math skills. 
We like the pressure that comes with timing our rounds. 

We can get through a whole round in 1:10 minutes. I think this game would work best with four or more players, otherwise it becomes a wee bit too confusing! 

We'll let you know when we beat our record time!
