It takes some time to get through this material, but one of the best math sites I have found is Annenberg. They're out of Boston and they have lessons you can read through, but they also provide video of both teacher learning sessions and classroom sessions. Math forum is also good, but may be a little higher level for middle level students.

Does anyone have any recommended websites to use to practice the algebraic ideas presented in this class?
