When my son was in third grade, he studied the United States. I was extremely grateful for the tools I found at Notebookingpages.com. We used these two sets: USA Notebooking Pages and State Birds, Flowers, Flags and Seals of the United States It made it so much easier to learn about the states because there was an easy format to follow and it included the state birds, flags and flowers.
As he got older, I used blank notebooking pages to create personalized notebooks for him. When Notebooking Pages added the web-app, I created handwriting sheets and workbooks geared to our textbooks and living books. I highly recommend Notebookingpages.com! They have a giveawy going on. Check it out.
