I am really excited about a new book I picked up at a Borders that was going out of business. It's called Painless Life Science and seems to be written in such a way that Justin can cover a chapter a week and we can do a review and/or test at the end of the week to see how much he retains. It was 40% off (score!) and looks to have enough chapters for the rest of the year's curriculum. Plus, I was able to read the first few chapters and understand it without "knowing" everything. To me, that means that Justin will be adequately challenged without being overwhelmed. As I looked for a link for it, I saw that the author has several other books in the series. I am DEFINITELY going to keep it in mind when I look for new curriculum for the kids! I'll let you know how it works out!
