The Flat Stanley Project was started in 1995 by Dale Hubert, a third grade schoolteacher in London, Ontario, Canada. It is meant to facilitate letter-writing by schoolchildren to each other as they document where Flat Stanley has gone with them. Dale Hubert received the Prime Minister's Award for Teaching Excellence in 2001 for the Flat Stanley Project.
The Project provides an opportunity for students to make connections with students of other member schools who've signed up with the project. Students begin by reading the book and becoming acquainted with the story. Then they make paper "Flat Stanleys" and keep a journal for a few days, documenting the places and activities in which Flat Stanley is involved. The Flat Stanley and the journal are mailed to other people who are asked to treat the figure as a visiting guest and add to his journal, then return them both after a period of time.
Trust me, I will not be sending these captions to my nephew, but I thought it would be fun to be a bit off:
Ah look how pretty...don't look too closely then you'd see all the construction around the reflecting pool. Assholes are screwing up my picturesque views!
