I have done this beautiful project many times over the years. Fourth graders study Colorado History, so it integrates well with the classroom. Students first learned about the History of Postage Stamps.They learned that a person who collects stamps is called a Philatelic They chose their symbol and sketched a rough draft. Next students received a paper like a big perforated postage stamp. After drawing, going over the design with sharpies, they are beginning to paint with watercolors. The first few are just lovely.
