Teach Symmetry by Creating an insect collection - look at insect books and specimen art - yr - present in cardboard shadow boxes. I particularly like the shape of the first insect on the second row as inspiration for a repeating pattern.
Teaching Symmetry Check out this symmetry self portrait bulletin board from Pineapple Paintbrush. Each child is half photograph and half drawing. I am sure the kids would love taking part in this project!
