I am so excited to use this with the kids. I was at IHM with Nancy Larsen Science, which I use and love. See my YouTube channel for my reviews. I was able to take a sample CD and look through the teacher manual, student book, test book, and view both of the text and the teaching DVD’s. I was so impressed by the activities and the CD blew all of my kids away. So, look for a review in the fall after all of their products are finished. This is the CD that we listened to. Not a peep. No fighting. No yelling. And the ultimate test… when I tried to park the kids tossed a ROYAL fit. “Keep driving, Mommy!” From 8 to 13.
