I recently revisited a project from four years ago, in which I had each student choose a type of shape (rectilinear or curvilinear) and a set of analogous colors (from yellow to blue, from yellow to red, or from red to blue). After they each painted and arranged their cardboard shapes into a personal relief sculpture, I asked how they would feel about combining them. (They looked so pretty-like a large stained glass window laid out on a large table together). Eight students agreed, so I got out the hot glue gun and combined them into what now hangs from the hall ceiling with 2 pieces of wire. It ended up being 6 foot tall, and there are enough individual personal relief sculptures to brighten our classroom as well.
