Don’t want to forget the movies …

http://www.stevewyborney.com/?p=556  — this is a quick video showing finding the mean as “leveling off.”   It’s done with number rods and it’s short and sweet (and not too many words).   I’m not sure students would see the connection between that and means in the context of real situations but that could be addressed.

A tweeet in the MTBoS (Math Twitter Blog-o-Sphere, I think)  says when asked that no, secondary math teachers don’t think they need to learn about pedagogy (tho’ obviously that’s not universal – they’re out there in the MTBoS :))  Still… that would help explain popularity of online videos… and is something to ponder…
