CUSTOMARY CAPACITY UNITS GRADE 3

Hello, How are you doing? Today, we are going to start a new lesson on customary capacity units.

Capacity Capacity is defined as a measure of dry or liquid volume of a container. Example – The capacity of the container is 1 gallon.

Customary Units of Capacity Customary Units of capacity are –  Cups (c)  Pint (pt)  Quart (qt)  Gallon (gal)

Relation in Customary units 1 pint (pt) = 2 cups (c) 1 quart (qt) = 4 cups 1 quart (qt) = 2 pints (pt) 1 gallon = 4 quarts (qt)

Choose the better estimate. a) 10 c b) 10 qt

How many pints (pt) are there in a a) quart? b) a gallon Answer- a) 2 b) 8

How many quarts are there in 5 gallon? a) 10 b) 20 c) 30 d) 40

Let us practice some problems now!

Write the objects in order from greatest to least capacity. Bathtub, glass of water, bucket

Convert 10 pt to cups

A big bottle of juice can be emptied in 8 cups. What is the capacity of the bottle of juice?

Compare using >, < or = a) 18 qt О 4.5 gal b) 2 gal О 12 qt

Fill in the Blanks. a) --– qt = 4 pt b) --- c = 18 pt
