Symmetry and reflection.
Using a mirror to explore symmetry creates an immediate, self-generated visual result that is personally engaging. Students who discover their own facial asymmetry or find symmetric patterns using physical mirrors retain the mathematical concept of reflection significantly better than those who study symmetry in textbook diagrams.
1. Hold mirror to letter A. 2. Does it look same? 3. Try B C D E. 4. Find all symmetric letters.
