# Understand and Estimate Customary Units of Length

- Grade 2 Math

Estimate Length - Customary Units Worksheet focuses on familiarity with customary units of length e.g. inches and feet and their relative magnitude. There are two key concepts addressed here:

- Choosing an appropriate unit to express length of real life objects. For example, inches and feet can be used to express length but not pounds or ounces. Also, an inch is more appropriate to express the length of a small object than feet.

- Choosing an appropriate estimate of lengths of real life objects. For example, 3 feet is a better estimate of the height of a table than 3 inches.
