This is a great classroom visual chart that measures 22" x 17" to show the 5 different ways to measure objects. The first way is by length, area, weight, volume and size of angle. The second is metric measures and customary units. The third is perimeter, area, surface area, and volumes. The fourth is area. And, the fifth is scale. Chart is based on the NCTM standards.
