  • Ask kids where they might find these shapes in life, and why measuring angles of polygons could be usable
  • Once kids have completed this, use the information they calculated to learn more about angles and polygons—why would the angle sum for the hexagon be less than that for the 24-gon?
  • Fun Fact: a 24-gon is sometimes referred to as an icosikaitera
