Measurement

1. Relate the number of units to the size of the units used to measure an object; e.g., compare the number of cups to fill a pitcher to the number of quarts to fill the same pitcher.
Measurement Equivalents

2. Demonstrate and describe perimeter as surrounding and area as covering a twodimensional shape, and volume as filling a threedimensional object.

3. Identify and select appropriate units to measure:
a. perimeter – string or links (inches or centimeters).
b. area – tiles (square inches or square centimeters).
c. volume – cubes (cubic inches or cubic centimeters).

4. Develop and use strategies to find perimeter using string or links, area using tiles or a grid, and volume using cubes; e.g., count squares to find area of regular or irregular shapes on a grid, layer cubes in a box to find its volume.
