Customary Measurements Capacity and Volume 1 gallon = 4 quarts 1 gallon = 128 fluid ounces 1 quart = 2 pints 1 pint = 2 cups 1 cup = 8 fluid ounces Length 1 mile = 1,760 yards 1 mile = 5,280 feet 1 yard = 3 feet 1 foot = 12 inches Mass and Weight 1 ton = 2,000 pounds 1 pound = 16 ounces

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

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. Capacity

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)

Length Pull 1 foot = 12 inches 1 yard = 3 feet 1 mile = 5,280 feet

·inches (in) ·feet (ft) ·yards (yd) ·miles (mi) 1 mi = 5,280 ft 1) linear (how long something is) 1 ft = 12 in 1 mi = 1,780 yd 1 mi = 5,280 ft 1 yd = 3 ft ·inches (in) ·feet (ft) ·yards (yd) ·miles (mi)

Capacity: U.S. Your robot should similar to the one shown here. Use the robot to help you answer the questions. Write the answers below. How many pints are in two quarts? How many gallons will eight quarts make? How many cups do you need to fill a quart? How many cups are in a ½ gallon? How many cups are in one pint? answer 4 answer 2 answer 4 answer 8 answer 2

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.

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.

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

·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

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

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

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. 2 + 2 + 3 + 3 = ________ feet

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.

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!
