I also use the Flat Stanley book in my class. I have each child send a Flat Stanley letter to a relative (with parent permission), I request that they send it to another relative, then to another relative. I keep having the letter sent on and on. I request that each family that reads the Flat Stanley to send a postcard back to our class. I put up a USA map and then as the postcards come in we locate where that postcard came from and mark the sight with a push pin that has a small Flat Stanley taped on to it. This is great to help the second graders become familiar with our country. Hope this help, it is a great project.
