U.S. Customary System of Measurement

3. Essential Question
How do we add, subtract, multiply or divide with U.S. measurements?

4. Weight or Mass Mass: quantity of material that makes up the object
Weight: measure of the earth’s gravitational pull on the object
Common U.S. measuring units = ounce, pound, and ton
Conversions:
16 ounces (oz) = 1 pound (lb)
2,000 pounds (lb) = 1 ton (T)

5. Capacity or Volume
For both liquid and dry capacity measures (dry capacity measures rarely used)
Common U.S. measuring units: ounce, cup, pint, quart, and gallon
Conversions:
3 teaspoons (t) = 1 tablespoon (T)
2 tablespoons (T) = 1 ounce (oz)
8 ounces (oz) = 1 cup (c)
4 cups (c) = 1 quart (qt)
2 cups (c) = 1 pint (pt)
2 pints (pt) = 1 quart (qt)
4 quarts (qt) = 1 gallon (gal)

6. Unit Ratio (1-21) Ratio is a fraction
Unit ratio is a fraction that has a value of 1 (ex: 1 day/24 hours or 1 yd = 3 ft)
Common way to say a ratio is to use the word “per” (ex: in/ft is said “inches per foot”
Practice:
7 yd = ? Ft
28 ft = ? yd

7. Measures (23-29) Mixed Measures: measures that use two or more units
Standard Notation: The number associated with each unit of measure is smaller than the number required to convert to the next larger unit
Practice putting these measures in standard notation
1 mi 6375 ft
1 gal 5 qt
5 lb 25 oz
6 qt 20 oz

8. Addition (31 – 41)
You attempt to make your own Arnold Palmer drink by adding 2 gal 2 qt 1 pt of iced tea to 3 gal 1 qt 1 pt of lemonade. What is the total volume of your Arnold Palmer?

9. Subtraction (43 – 55)
A dump truck is loaded with 5 tons of gravel. After it unloads 570 lbs 9 oz of gravel, how much weight will it be carrying?

10. Multiplication (57 – 69)
A recipe calls for 1 c 3 oz of mil. How much milk will you need to triple the recipe?

11. Division (71-85)
After a party, there is 4 gal 3 qt of punch left. If the punch is divided among 3 people, how much does each one get?

12. Division….try again
You have 8 yd 2 ft 4 in of string to make into bracelets. The bracelets need to be 7 in long. How many bracelets can you make?
