This is fun - Russian Math!

I was reading some posts on a home school website about kids and counting with their fingers. Alex really doesn't do that very much. He is able to do addition with his head. When I ask him a question, his chin goes in the air, he squints a little and you can see him mentally working it out.

One of the moms put a link to this site with a little trick to doing higher multiplication from www.stumbleupon.com. I thought it was pretty cool.
