1 Student Activity 1 Name Measure Up Label each ruler with the correct measurements. The rulers are in inches. Use a ruler and draw a line that is: /4 inches /8 inches Be Precise Student Materials Page 1 of 10

2 Student Activity 2 Use a standard ruler and label to the nearest 1/16 th of an inch for the first inch and to the nearest 1/8 th of an inch for the rest of the ruler. Cut out to use. Student Activity 2 Name Use your ruler to measure each line to the nearest 1/8 th of an inch. Be Precise Student Materials Page 2 of 10

3 Student Activity 3 Name Which Unit? Using Precise Measurements Think about what tool you would use to measure each object. Choose the correct unit to measure each object: Inch, Foot, Yard, Mile Be Precise Student Materials Page 3 of 10

4 Student Activity 4 Name Precision Measurement Before you begin Decide which tool to use Decide on the unit of measure to use Estimate each measurement Item Length of pinkie finger Measuring Tool Unit of Act Measure Estimate ual Measurement E- M Length of hand Arm to elbow Foot Height Thickness of math book Length of pen Length of desk Width of desk Height of door Width of door Your choice Your choice Your choice 1. If you could only use one tool to measure these objects, which tool would you use? Be Precise Student Materials Page 4 of 10

5 Explain why you would use that tool. 2. Look at the last column of the table. Were most of your estimates less than the actual measure or greater than the actual measure? Explain why you got that result? How could you refine your estimate? 3. Record your measurements for the desk and the door. Desk/Table Length Door Length Width Width Use the measurements to find the perimeter of each object. Perimeter of desk= Perimeter of door= Label each answer with the correct units. Why is this unit the most appropriate for this type of measurement? Now find the area of the desk and the door. Area of desk= Area of door= Label each answer. Explain what the differences are between an object s perimeter and its area. Be specific. Be Precise Student Materials Page 5 of 10

6 Student Activity 5 Name Basketball Counts-Converting Measurements What makes height so important in basketball? Is it the only thing that matters? Is precision in measurement important in sports? Try this activity. Use the measurements from Student Activity 4. Convert your measurements to the correct units. You may need to re-measure some of your objects for precision. 1. What was the measure of the length of your hand to the nearest ¼ inch? To the nearest 1/8 inch? 2. Using the measurement of your height in inches, convert it to feet and inches. feet inches Explain how you found the answer using words or showing your steps. 3. List the heights of five people in your class using measurements to the nearest ½ inch. Name Height to nearest ½ inch Be Precise Student Materials Page 6 of 10

7 This is going to be your class basketball team. What is the average height of your team to the nearest ½ inch? Explain how you found the average. 4. Explain why a coach would want to use precise measurements to determine the height of his players. 5. What other qualities would you want on your team other than tall players? 6. Go to the school gym. Measure the length of the free-throw line from the end of the court to the line where you stand to shoot.. Measure the width of the free-throw line from one side of the key to the other. What is the most precise way to measure the perimeter of the free-throw region? Perimeter= Label the units. 7. Measure the perimeter of the basketball court. Make a sketch of the court and label the dimensions. Be sure to use correct units. Length Width Total Perimeter Be Precise Student Materials Page 7 of 10

8 What is the area of the basketball court? What unit is the best for this measurement? Explain why you selected this unit. 8. Give examples of something in your school gym or around the school that can be measured in each of the units listed and explain why that is the appropriate unit to use. Inches: (object) Explain unit Feet: (object) Explain unit Yards: Explain unit Miles: Explain unit: 9. Describe why precision in measurement is important. Be Precise Student Materials Page 8 of 10

9 Student Activity 6 Name Can You Convert?? Units of measure need to be precise to be useful in everyday situations and solving problems. Complete the following conversions. Use your ruler, a 12 inch ruler or a yard stick as needed. 12 inches = foot 6 feet 4 inches = inches 3 feet = yard 2 yards 2 feet = inches 1 yard = inches 28 inches= feet inches 3 ½ feet = inches 1 mile = feet 3 ½ feet = yards 1 mile = yards 4 feet 9 inches 5 yards 2 feet 9 feet 3 inches + 5 feet 6 inches +3 yards 1 foot -4 feet 8 inches Be Precise Student Materials Page 9 of 10

10 over Look around the classroom. Find an object that is approximately the given length. Answer the questions below. Approximate Measurement Object Another unit of Measure 14 inches 22 inches 4 feet 6 feet Challenge: Perimeter of 20 feet Area of 24 square feet Be Precise Student Materials Page 10 of 10
