This easy mask project always has a high success rate. I usually have students make and paint the masks on day one. Hold off on stapling under after the paint dries. On day two, we staple then embellish with sequins, oil pastels, and feathers.
You can simplify the project by using colored tag board with oil pastels. That way students can make and take their mask in one class period.
If your students want to wear their mask, use a hole puncher to make a hole near the two staples. If you attach one pipe cleaner to each side, students will be able to twist them behind their head without needing your help.
