Thank you for the recommendation on Aleks. We did the assessment and some lessons last night as part of a free trial. It is great! DS has ADHD, inattentive type, so he tends to rush as quickly through work as possible. He is not motivated by grades, so he really does not care if he gets the answer wrong. He just wants to get the work done and move on. Well, Aleks won't let him do that. He has to get the answers right in order to be "finished". He was so frustrated, but it is just what he needs. I LOVE IT!!! Thanks again!
