speaking of ALEKS, DS just brought home a sheet freom AdaptedMind Math with a username and password--his teacher wants him to do it. So far it looks good. It teaches the concepts like ALEKS or ixl.com and if they get 5 or 10 in a row correct it "passes" them and moves onto the next thing. I'm not sure if there was a placement test involved or not. So I need to look up how much it would cost to add DD, or maybe I can ask her teacher if she has access to it.
