Here is a neat one on transforming equations...

Nothing extraordinary, other than reminiscing, but at 18:50 he previsions the use of a "classroom clicker" when he asks the students to mouth the answer so that the others cannot hear. Anyone notice him asking on only the brightest kid (that would be the boy at the far right middle of the classroom)? At 17:00 you find out what happens to the brightest kid in the class.:)
Do most of you force the students through every step in these transformations?
