Our annual post office project is almost up and running. This year, I added a few components so it's taken a bit longer to get the post office ready to open. Second grade students made paper circuit cards to sell this year, in addition to the standard post cards and stamps. Also, they created organizational tools for sorting the mail and carrying devices to get the mail around the school. Sorting devices included conveyer belts and shelving and backpacks and satchels were made for carrying mail.
