We used the Middle Ages Level 1 curriculum for 4th grade history/social studies. I really liked the lay out and ease of use of the program. There are lots of book choices to round out the curriculum, easily ordered fro your local library. Each week, I would look at the next week's lesson, order the books from my library, and mark the pages in the supporting texts (Story of the World and A Child's History of the World). It definitely made my planning easier, and my child could easily see what she had to do in a lesson. My child was valso ery engaged by the projects, map work, and history readings. Highly recommend.
