We discovered Khan Academy last week.  Stan uses video to illustrate a math idea, then you can practice this concept, all the while earning points.  Milo and Danielle are slowing working their way through the videos.  Each student has to have an e-mail in order to keep the points separated... so Milo is using mine and Danielle is using Toris.... or the other way around... or maybe we've confused them who knows...

Great plan... THANK Khan Academy!

It's free.
