CONFIDENTIAL 1 Today we will review “Measurement”

CONFIDENTIAL 2 Let’s Warm up 1) ¼ + ½ = 2) 3/5 – 1/5 = 3) 3/8 + 3/8 = 4) 5/8 – 10/16 =

CONFIDENTIAL3 Customary Units of Length Nonstandard units of measure give approximate dimensions. Everyday objects are used as units of measure. It can be used to measure length, height and width.  The desk is as long as 6 of my hands Length: The measurement of distance between 2 endpoints.  The length of my arm is 18 inches Height: The measurement of distance from bottom to top.  Her height is 68 inches Width: The measurement of distance from side to side.  The width of the stripe is 2 inches

CONFIDENTIAL4 Try This! Use your hands to find the length of the computer monitor Use nonstandard units to measure the length of a pencil

CONFIDENTIAL5 Explore Customary Length to ¼ inch An inch (in.) is used to measure short lengths in the customary system. You can use a ruler, yardstick or tape to measure in inches CRAYON

CONFIDENTIAL6 Explore Customary Length to ¼ inch The foot (ft) and yard (yd) are used to measure larger units in the customary system. 1 yd 1 ft

CONFIDENTIAL7 Explore Customary Length to ¼ inch Customary Units of Length 1 foot (ft) = 12 inches (in.) 1 yard (yd) = 3 feet (ft) 1 mile (mi) = 1,760 yards (yd) 1 mile (mi) = 5,280 feet (ft)

CONFIDENTIAL8 Try This! Measure the length of your forearm Measure the length of a book

CONFIDENTIAL9 Customary Units of Capacity Capacity: A measure of a dry or liquid volume of a container. The container has a capacity of 1 gallon  A coke drink is about 12 fluid ounces.  A regular cup of coffee is about one cup.  A can of oil for the car is about one quart.  A large milk container is about a gallon. Customary Units of Capacity 8 fluid ounces (fl. oz) = 1 cup (c) 2 cups (c) = 1 pint (pt) 2 pints (pt) = 1 quart (qt) 4 quarts (qt) = 1 gallon (gal)

CONFIDENTIAL10 Try This! What unit would you use to measure the capacity for each?  A bathtub  A soup bowl  A paper cup

CONFIDENTIAL11 Customary Units of weight Weight: A customary measurement that tells how heavy an object is.  The dog’s weight is 12 pounds  A strawberry’s weight is 1 ounce (oz)  A pineapple’s weight is 1 pound (lb)  A car’s weight is 1 ton (T) Customary Units of Weight 16 ounces (oz) = 1 pound (lb) 2,000 pounds (lb) = 1 ton (T)

CONFIDENTIAL12 Try This! What unit would you use to measure the weight for each?  A math book  An elephant  A paper napkin

CONFIDENTIAL13 Simple conversions with Customary Units Convert: Change from one unit to another, such as from feet to inches. Change Larger to Smaller units  To change to a smaller unit, multiply.  Example: How many inches are in 6 feet? 12 inches = 1 foot 6 feet = 6 x 12 = 72 inches Change Smaller to Larger units  To change to a smaller unit, divide.  Example: How many feet is 48 inches? 1 foot = 12 inches 48 inches = 48 ÷ 12 = 4 feet

CONFIDENTIAL14 Try This! How many quarts is 4 gallons? How many pounds is 560 ounces?

CONFIDENTIAL16 Metric Units of Length Centimeters (cm), millimeters (mm), decimeters (dm), and kilometers (km) are used to measure length in the metric system Metric Units of Length 10 millimeters (mm) = 1 centimeter (cm) 10 centimeters (cm) = 1 decimeter (dm) 100 centimeters = 1 meter (m) 1,000 meters = 1 kilometer (km) 1 cm 1 mm 1 dm

CONFIDENTIAL17 Estimate Estimate: An answer that is close to the exact answer.  12 x 779 = 9,348  12 x 800 = 9,600  Estimate Estimate is used to get an idea of how large the object is; to pick appropriate units

CONFIDENTIAL18 Try This! Estimate and then measure. Tell what unit and tool you use.  The width of your room  The largest step you can take

CONFIDENTIAL19 Metric Units of Capacity Capacity: A measure of a dry or liquid volume of a container.  Ounces are customary units of measurement  Milliliters are metric units Metric Units of Capacity 1,000 milliliters (mL) = 1 liter (L)

CONFIDENTIAL20 Try This! Estimate and then measure the capacity of each object. A juice box A spoon

CONFIDENTIAL21 Metric Units of Mass Mass: Amount of matter an object has. The mass of a math book is 1 kilogram. Customary Units are used in US Metric Units are used by most countries Metric Units of Mass 1,000 grams (g) = 1 kilogram (kg)

CONFIDENTIAL22 Try This! Estimate and then measure the mass of each object. A bicycle A pair of sneakers

CONFIDENTIAL23 Convert Metric Units Metric Units Length1 centimeter (cm) = 10 millimeters (mm) 10 centimeters (cm) = 1 decimeter (dm) 10 decimeters (dm) = 1 meter (m) 1,000 meters (m) = 1 kilometer (km) Mass1 kilogram (kg) = 1,000 grams (g) 1 gram (g) = 1,000 milligrams (mg) Capacity1 liter (L) = 1,000 milliliters (mL)

CONFIDENTIAL24 Convert Metric Units Change Larger to Smaller units  To change to a smaller unit, multiply.  Example: How many centimeters are in 10 meters? 1 m = 100 cm 10 meters = 10 x 100 = 1,000 cm Change Smaller to Larger units  To change to a smaller unit, divide.  Example: How many kilograms are in 5,000 grams? 1,000 g = 1 kg 5,000 ÷ 1,000 = 5

CONFIDENTIAL25 Try This! 5 m = __ cm 5,000 g = __ kg
