Wow! I've heard of this website, but had not check it out. I loved all the online videos and many ways that students can practice their skills.

I first heard of this website from one of Dr. Butler's seminars last fall. I also saw it on the news show "60 Minutes" a couple of months ago. There are so many videos for a teacher to choose from. I showed a couple of the videos to my fourth grade class on place value. I will try to work some more videos into my lessons.
