How much time did your son put into the 4th grade Aleks? Did he work on it all summer? This sounds like a wonderful option. Wonder if I should have him start with the 3rd Grade or 4th Grade Aleks. What are your thoughts? Would their customer service be good for advisment? We are running out of time school starts on Aug. 24th, The beggining of the year is a lot of review. The students are expected to practice their facts so maybe he can do it on Alek.
