We started of this unit by checking out some books at the library. I knew of the more longer chapter books, but, I had no idea they had My First Little House books. This was perfect! I also got a chapter book for younger kids. It's the School Days one below. As soon as we started reading the books, I went back in time to my youth. I loved Little House on the Prairie. Of course, I had to explain a lot about what they didn't have back then, that we have now.
