I planned to start a clay unit with my 4/5 combined art class today, but half my students were out of the building on a field trip today while the other half was raring to go. After considering a few different options the kids chose giant coil pots as the activity of the day. Easy for me and good practice for them. They broke into groups to see who could build the biggest coil pot. A whole lot of clay later here's the winner.
