2. 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.
tape measure
ruler
yardstick

3. Ways to Measure
There are many times when we want to measure something.
We can measure to find:
Length
Weight
Weight tells how heavy something is.
Weight
Capacity
Length
Length tells how long something is.
Capacity tells how much liquid a container will hold.

4. These are the units of measurement we use in the United States.
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)

14. Capacity: U.S. Customary
Instructions
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.

19. drag the correct measurement
Which capacity unit would
you use to measure ....
fluid ounces
cup
·the water in a bathtub
·a coffee mug
·a water bottle on your desk
·a rain drop
·a swimming pool
·a large jug of milk
pint
quart
gallon
drag the correct measurement

20. Weight: U.S. Customary
If an object weighs less than a pound, its weight can be measured in ounces. Place each object on the scale. Guess if its weight is shown in pounds or ounces.

21. Weight
Pull
1 pound = 16 ounces
1 ton = 2,000 pounds

22. ·ounce (oz) ·pound (lb) ·Ton (T) 1 T = 32,000 oz 1 lb = 16 oz
3) weight (how heavy something is)
·ounce (oz)
·pound (lb)
·Ton (T)
1 lb = 16 oz
1 T = 2,000 lb
1 T = 32,000 oz

23. drag the correct measurement
Which weight unit would
you use to measure ....
ounce (oz)
pound (lb)
·your weight
·a school bus
·a feather
·a dime
·your desk
·an elephant
·your pencil
Ton (T)
drag the correct measurement

24. Weight
Which weighs more? Have students rotate the scales so that the heaviest side is lower.

25. Perimeter
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 is the total distance around the outside of a polygon, or shape.
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 3 3 2
To find the perimeter, add the length
of each side. Write the answer.
= ________ feet

26. Area
Instructions
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.
length
width
= area x
Have two students draw six equal squares and assemble them into a rectangle. This rectangle represents the area of the cage.

27. Weight: U.S. Customary Drag the correct word to complete the sentence.
An ounce (oz.), a pound (lb.), and a ton (T.) are
U.S. Customary units used to measure weight.
16 ounces (oz.) = 1 pound (lb.) 2000 pounds (lb.) = 1 ton (T.)
Touch the bread.
A slice of bread weighs about one ounce. Sixteen slices weighs about one pound. 2,000 loaves of bread would weigh about 1 ton!
