The Good and the Beautiful Math K Course Book, Parts 1 and 2

My son has finally finished both parts 1 and 2 of The Good and the Beautiful Math K *original version. This was a beautiful experience and after a while, he took off on his own. I don't know if it is because of this book or his own innate ability, but he is now nearly testing on a fourth-grade math skill diagnostic. I showed him all sorts of other options to move to next and he chose to continue into The Good and the Beautiful Math 1 *original version. (I already have Math 2 on the shelf for him as well, and while his sister is doing Math 3, by the time he gets there we will have to look into the new Simple and Beautiful Math as the originals are now phasing out.) He also does IXL and now has added in Teaching Textbooks 4.0 online Math 3.

I love the stories, the full-color, the simple short lessons, and the manipulative box and activities. I do not like the large books that do not last the time of the course.
