Oliver Neel, a professor at Harvard, has a collection of 40+ clips from popular movies that deal with math in some way. They're available both as flash and quicktime files, and shouldn't trigger any school district website filters. Awesome!
Alice in Wonderland- Unbirthdays.
"What are the chances two people in the same class have the same birthday?"
Stand and Deliver- Variables and Giggolos.
"How do you turn word problems into algebraic expressions?"
Like Mike – Supersized Triangles
"What mnemonics can we use to remember names of shapes?"
Thanks to John Domecus, Aptos 8th grade Math teacher, for the tip.
