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 uses the Sieve of Eratosthenes as a graphic visual (get it?) to help students see how one might reduce the numbers from 1-100 to just the primes.

This video is part of the video collection at NextVista.org (http://nextvista.org), a proud partner of Curriki.
