Grade: 10 Specific Expectations: use the imperial system when solving measurement problems perform everyday conversions between the imperial system and the metric system and within these systems, as necessary to solve problems involving measurement Proceed to Lesson 2
Yards, Feet, and Inches Probably the earliest appearance of the measurement known as the yard is attributed to the Saxons. They defined the yard as the circumference of the human body, or gyrd in the language of the time. In 1101 King Henry I of England issued a decree defining the yard as the distance from his nose to his outstretched arm. Use a yardstick to determine how closely your "yard" matches the king's yard. The yard was divided into 3 feet, each of 12 inches. Next 3
Investigate The Relationships Among Imperial Units Units of measure are grouped into units of length, units of mass/weight, units of volume, and units of temperature. Predict the most common imperial units using the blank table. Then, pull the completed table to the workspace to check your predictions. to learn about British imperial measure and U.S. imperial measure. 4
Units of Length 1. a) Use a yardstick. Determine the number of inches in one foot, and the number of feet in one yard. As well as the number of inches in a yard. b) What is the smallest fraction of an inch shown on the yardstick? Units of Weight 1. a) With the assistance of technology, find out how many ounces are in a pound? b) I believe I was 7lbs, 9 oz. when I was born, can you represent this as one number (i.e. using a decimal) Units of Volume 1. a) With the assistance of technology, can you find: tsp = 1 tbsp tbsp = 1 cup fl.oz. = 1 cup pint = 1 quart quart = 1 gallon 5
Example 1: Measure to a Fraction of an Inch Find the length of each object to the smallest fraction of an inch. Solution Drag the ruler to the object. Estimate the length measurement. Adjust the pink arrows as necessary. Click on the grey arrow to check your answer. Previous Next 6
Example 2 Working With Volume Steve owns a restaurant in Arizona. He bought a 55 gal drum of ketchup at a wholesale store. For the tables, he has 1 pint squeeze bottles that he fills 2 with ketchup from the drum. How many bottles can Steve fill from this drum of ketchup? Solution Find the number of pints in the drum. There are 440 pt in 55 gal. Steve can fill 880 squeeze bottles. Previous Next 7
Example 3 Find the Cost to Carpet a Room Calculate the cost, including taxes, to carpet the floor shown. The carpet costs $24 per square yard. Solution Calculate the area to be carpeted: The area to be carpeted is 204 sq ft. Convert the area to square yards. 2 3 The area to be carpeted is 22 sq yd. Calculate the cost of the carpet: Find the total after adding tax: It will cost $614.72 to carpet this room. Click to use a carpet calculator. Previous Next 8
