For 3rd grade art we learned how to make symmetrical butterflies by drawing on half the paper with oil pastel then rubbing to transfer the image to the other side. Then they painted their butterflies with tempera paints. It took two sessions and the kids really enjoyed themselves. I made a mural with all their butterflies, along with tissue paper butterflies from the kindergarten and second grade. The mural also included leaves painted by 3rd and 5th graders and grass cut from the textured paper the 1st graders made for their ladybug collages. I love how cheerful in turned out!
