Customary Measurements
Length: U.S. Customary
The measurement of length uses different units. In the United States, we measure length in inches, feet, and yards. These are called U.S. Customary units. We use different units of measurements. The activity on the next page will help you learn about the units that these tools use for measuring.

In the United States, we use these tools to measure length.
There are many times when we want to measure something. We can measure to find:
Capacity tells how much liquid a container will hold.

Ways to Measure
Customary Units
These are the units of measurement we use in the United States.
There are 3 ways we measure things.
1) linear (how long something is)
2) capacity (how much liquid something will hold)
3) weight (how heavy something is)

Let's build a robot to help us remember how the units of capacity work together. Drag the gallon to the middle of the screen. One gallon equals four quarts. Drag the four quarts to make two legs and two arms. (The four quarts should be the top part of the arms and legs.) Two pints equals one quart. Eight quarts equals one gallon. Drag the eight pints to extend the arms and legs. (Show two pints below each of the four quarts. Do not mix with cups.) Two cups equals one pint. Sixteen cups equals one gallon. Drag the sixteen cups to extend the arms and legs even further. (Show two cups below each pint. Do not intersperse with other units of capacity.) Finally, draw a head on top of the robot.

Your friend bought a cage for her guinea pig. Your friend wants to know the perimeter of the top of the cage. Let's measure it to find out how big it is! Look at the cage from the top.
Perimeter
Perimeter is the total distance around the outside of a polygon, or shape.
To find the perimeter, add the length of each side. Write the answer.
The two longest sides are each 3 feet long. The two shortest sides are each 2 feet long. Drag the 3’s to the two longest sides.Drag the 2’s to the two shortest sides.
2 + 2 + 3 + 3 = ________ feet
Area
Have two students draw six equal squares and assemble them into a rectangle. This rectangle represents the area of the cage.

We can also find the area of the bottom part of the cage.
Area is the amount of surface a shape covers. It is measured by the number of square units inside of the figure.
In this case, we are finding the area of a rectangle that is two feet long and three feet wide. The area of a rectangle is equal to its length multiplied by its width.
