This is one of the projects that a second grade class completed for the school's art show. We started off by creating a very shallow "box" or "tray" from a piece of black construction paper. I gave them a 12" square piece of black construction paper and showed them how to cut the corners and fold it up to create the box. Then I gave them 1/2" wide strips of paper to create walls within the box. I taught them to fold the ends over and glue the folded ends to the sides of the box. Then we raided the scrap paper box. I demonstrated to the students how to cut strips of various widths of paper and curl them around a pencil or crayon. Then the edge of the coils are dipped into glue and the coil is placed within the box. Each separate area created by the walls in the box is filled in with a different color.
