I, too, am just leaving HOD for SCM. I think HOD’s books are great, and she does a great job putting a curriculum together. But the separation of subjects was something I didn’t love. And, as one poster said, the author doesn’t really recommend combining either. (Sad!) I also feel that a couple of things were twaddle-ish. It might be great for those that are interested in some of those activities (i.e. some particular science experiemnts, etc.), but it was just unnecessary to me. If I didn’t have a bunch of kids, I would probably still love it, but I’m leaving it so that I can not feel so tied down to checking off the boxes and getting it all done. And can instead cuddle up with all my kiddos together and enjoy them, and read to them, and teach them in a more lovely way. 🙂
