After recycling thousands of colorful pouch caps, an idea HIT me! I reached out to my friends and family, all of whom have young children, and asked for them to save their pouch caps. I wasn’t sure what would happen with them, but I knew I would come up with something. When we began discussing symmetry in grade 5, I realized that working hands on would be a much more effective way of using linear symmetry than the traditional method of finding the other half of a picture. THE CAPS!! Working in groups, students used the pouch caps along with a line of symmetry to create linear symmetric designs. The activity promoted cooperation as well as an understanding of the concept. This was the perfect starting point for a unit which then led in to rotational symmetry and finally our culminating activity of mask making. **Kindergarten and grade one used the caps for pattern making! Such a fun and FREE manipulative!!! Please keep your caps and send them in with your student!!!
