This is one of three videos a team and I did to try using video to convey prime number ideas to middle school students. This one takes a more traditional approach, with me at a whiteboard explaining what primes are. A goal was to jazz it up, in terms... of sound effects and the like, just enough to get the message across. This video is part of the video collection at NextVista.org (http://nextvista.org), a proud partner of Curriki.
