It seems that they are focusing on the workbook which I was only able to glance through. It is pretty thick and my early impression is that it seems to have a better sequence of topics with more focus on the details of doing math compared to the EnVision series of books he had previously.
I won?t be able to do a full analysis until I have the book in my hands next week, but I am optimistic. I note that they chose the advanced course which probably helps. I don?t have access to to a copy of the regular course. Unfortunately, a lot of the stuff we did this summer is in the 2nd (7th grade book) and I will probably buy that one as well and bounce back and forth. The school he will be attending next year will expect (and require) preparedness. It is a real shame that you cannot find that quality in the majority of our public schools anymore.
