Have you ever watched a movie and found that one clip that would be totally awesome to use in classroom instruction?? Mathematics in Movies has done just that! This site contains an entire library of clips from movies that provide an interesting and entertaining way to introduce those "boring" math concepts. Clips are available in both flash and quicktime.
I read about this site on a blog by Jerri Davis and just had to pass it along! It's great to visit even if you aren't teaching math.
