A Third Grade Review!

Customary Capacity

• There are 4 main units of customary capacity!

• Gallons—Gal

• Quarts—Qt

• Pints—Pt

• Cups--C

Gallonsiant

Gallons are used to measure large amounts.

Capacity: The Gallon

• What do you think of when I say gallon? You probably think of the gallon of milk sitting in your refrigerator right now.

Quarts

Here is a quart of milk.

Capacity: The Quart

• You may also find milk in a quart container, which is smaller than both the gallon and half-gallon. You can also get paint in a quart.

Pints

Mason and Jelly Jars are about a pint.

Capacity: The Pint

• Guess what? Milk can also come in a pint. The kind of milk or juice you get in the cafeteria is a half-pint.

Cups

Capacity: The Cup

• A cup of milk is 8 oz. of the cow’s best!!! Don’t you wish you had a cup right now with a chocolate chip cookie to dunk in it? Yummy!!!

Relating Capacity Amounts

• Now that you know what the capacity amounts are, let’s look at how many of one container it takes to equal another container.

• 1 gallon = 4 quarts• 1 gallon = 8 pints• 1 gallon = 16 cups

• 1 quart = 2 pints

• 1 quart = 4 cups• 1 pint = 2 cups

Conversions

Use the Kingdom of Gallon!!

Draw the G for the Kingdom of Gallon.

Add 4 Q’s (quarts) for each of the four Queens in the kingdom.

Each queen had a princess and a prince (2 pints).

Each princess and prince had 2 cats (2 cups).

Try this one:

Ms. Itzhaki went to the store to buy 6 quarts of milk. They were out of quarts! She had to get pints instead. How many pints did she need to bring home the same amount of milk?

Since 6 qt = 12 pt, she needed to buy 12 pt!
