When I was student teaching two years ago I did this project with my 4th graders. We talked about Alexander Calder and his amazing sculptures. Students got some thick white paper and cut it into different shapes. (These shapes for the most part had to fit on there base). The made patterns on either sides of the shape. Then they cut slits in the shapes and connected them before they glued them to the base. I think I might put them on black bases next time around. Loved the results, but they took up a lot of space! Great for Fine Arts Night.
