# Understand and Estimate Metric Units of Length

- 2nd Grade Math**Estimate Length - Metric Units Worksheet** focuses on familiarity with customary units of length e.g. ** centimeter** and

**and**

*meter**their relative magnitude. There are two key concepts addressed here:*

- Choosing an appropriate unit to express length of real life objects. For example,

*centimeter*and

*meter*can be used to express length but not pounds or ounces. Also,

*centimeter*is more appropriate to express the length of smaller objects than

*meter*.

- Choosing an appropriate estimate of lengths of real life objects. For example, 3 meters is a better estimate of the height of a wall than 3 centimeters.
