It is so nice when there is a fine line between school and play. It makes you realize how much fun it is for them to learn. Here is a photo of James and the beaver dam he made out of Zoobs. He wasn't asked to do this as a school project. He just did it for fun after learning about them. And another photo of Quentin pretend that the stuffed bears are catching and eating salmon. As Charlotte Mason said, you don't have to make unit studies for your kids. Your kids will make their own connections.
