Slide 7 / 115 Slide 8 / 115 Standard Measurement Cups and Pints Standard Measurement System (US Customary) Converting From One Unit of Measurement to Another There are 2 cups in every pint. What happens if you are given a + = measurement in one unit, but need to use it in another? 1 cup 1 cup 1 pint For example, you are baking cupcakes, and the recipe calls for 4 cups of oil. The bottle of oil says that it contains 3 pints. How do you know if you have enough oil? In order to find out, you would need to do something called converting. You need to convert the unit of cups to the unit of pints. Slide 9 / 115 Slide 10 / 115 Cups and Pints Converting Measurement When converting measurements, use your arms to help you. So how many cups are there in 3 pints? We can spread our arms We can fold our arms out wide to show that in a hug to show that = + something is bigger. something is smaller. 1 cup 1 cup 1 pint + = 1 cup 1 cup 1 pint To convert a smaller unit to To convert a larger unit to a + = a larger unit, we divide the smaller unit, we multiply the 3 pints amount. amount. 1 cup 1 cup 1 pint 2 cups x 3 pints = 6 cups in 3 pints Slide 11 / 115 Slide 12 / 115 Conversions Conversions Troy has 6 popsicles that are 5 in long Another example: each. If he places them all in a line, how many feet would they be? I bought a set of 4 glasses from the market. A glass weighs 8 ounces. How many pounds does the set weigh? + + + + + 5 in 5 in 5 in 5 in 5 in 5 in = 30 in Find the total ounces: ___ oz x __ glasses = ___ oz. How many feet are 30 in? We are going from ounces to pounds so we are converting We are going from inches to feet, so we are a smaller unit to a larger unit. converting a smaller unit to a larger unit. Therefore, we need to ________. Therefore, we need to ________. _____ ___ lbs = 32 oz _____ = ___ ft ___ in X or 30 in X or (# of oz in a lb) (# of inches in a foot)

Slide 13 / 115 Slide 14 / 115 Standard Conversions Match-Up Fractional Measurements How can we write measurements using fractions? Think about what half a foot is in inches. If a foot is 12 in, then 1/2 a foot 12 ÷ 2. So, half a foot is 6 in. How many inches is a foot and a half? A foot and a half is 12 x 1.5. So, a foot and a half is 18 in. How many feet are there in 30 inches? 30 ÷ 12 = 2.5 So, there are 2 1/2 feet in 30 inches. Slide 15 / 115 Slide 16 / 115 1 12 yards = ______ ft 2 95 ft = ______ yds Slide 17 / 115 Slide 18 / 115 3 18 cups = _____ pints 4 6 gal = ______ pts
