Aleks has definitely worked for us. We like the Pie. There is something about filling in that Pie that makes it a little more fun for my son and he never thought math was fun before we found Aleks. He told me a few days ago that he feels really good after doing something challenging in math that he hadn't done before. He usually tries to find answers his way before looking at the way Aleks shows how to do it and it is usually different from the way I would do it, but it works for him. If he gets to the point where he needs to show his work more to avoid incorrect answers then he will make changes, because he definitely wants to get the three problems correct. I think he sometimes goes back through the steps mentally before submitting his answers. Sometimes he asks me if it is correct. I then do the problem my way and if we get the same answer he enters it. Otherwise, he has to do it all over and figure out what he did wrong.
