Ancient Greece. I used folders for the pockets to store the work. The kind you get cheap during back to school sales.
The History Pockets are a great way to learn history. We used Ancient History in the examples above. They include vocabulary, dress, and architecture. My first and third grader loved them. The older kids enjoyed joining in some of the activities in the Ancient Egypt Book.
You can also buy a yearly subscription to TeacherFileBox.com through the Homeschool Buyers Co-op. You can access all of Evan-Moor teaching books and activities all year. You can download and copy what you need as you need it. I have enjoyed having it this last year.
