Thanks, onthegomom!
I've been using Brainpop for years and just introduced Mathletics to the students. Old Trail looks very interesting, so I'll be sure to check it out. Your info has definitely been helpful.
We currently have chat, but I've been looking into a virtual world chat environment (like Sims) where students can take quizzes, complete assignments and interact with instructors and peers.
BTW...If you like Brainpop and Mathletics, you should look into Gizmos and Adaptive Curriculum.
