1. Take 5-7 clear photographs with examples of symmetry in the classroom and playground
2. Identify how many lines of symmetry there are - 1, 2, horizontal, vertical, diagonal, multiple
4. Insert the images into a drawing programme and add the lines of symmetry
5. Insert the images into iMovie - explaining the learning point
Check out the rap this teacher made for his kids. I am sure you could make a better explanation for the kids to learn about symmetry.
