• WELCOME TO MATH!

So far we have looked at how to measure length and distance.
Today we will look at measuring amounts of liquid.
The term capacity means how much liquid a container can hold.

You are familiar with the terms 'gallon' and 'half gallon,' because Milk typically comes in containers of these sizes at the grocery store.
Milk is also available in 'quart' size, 'pint' size, and even 'half pint' size.
Q: What size carton of milk can you purchase at lunch from the school cafeteria?
A: Typically, a carton of milk at school contains 8 oz. of milk, which is a 'half pint.'

Please look at the containers of milk pictured on page 266, and compare their sizes.
A gallon is a unit of capacity used to measure large amounts of liquid.
A half gallon holds half the amount of a gallon container.
quart holds half the amount of a half gallon container, OR one-fourth (one quarter) the amount of a gallon container.

Okay, let's think about this. Would you rather try and measure the amount of water in a bathtub in cups or in gallons? If you had to scoop the water out of a full bathtub one container at a time, which container would be faster (and less work), a 1-Cup measuring cup or a 1-Gallon pitcher?

Let's look at number 7 on page 267 together, and follow along with how they ask you to think about the problem.
If there are two cups in a pint, then we can use multiplication to figure out how many cups are in two pints:
a. 2 cups in a pint X 2 pints = 4 cups
b. 2 cups in a pint X 3 pints = 6 cups
c. 2 cups in a pint X 8 pints = 16 cups

Below is a link which will take you to Discovery Education for a further explanation of capacity (how much a container can hold).
