|Lesson Title: Central Tendency |Date: |
|Subject: Math |Grade Level(s): 8 |
|Teacher: |Time Frame: 60 minutes |
|Lesson Summary: |
|Students will be able to calculate three common measures of central tendency (mean, median, and mode) and find a measure of the spread of data (range). |
|Lesson Objectives |
| The students will know… |
|That central tendency is the tendency of the sample of a given measurement to cluster around some central value. |
|How to calculate three common measures of central tendency (mean, median, and mode). |
|How to find a measure of the spread of data (range). |

|Lesson Plan |
|Time: |Procedure: |Materials Needed: |
|5 minutes |Warm-up Exercise: |Centimeter tape measure; index cards |
| |As the students come into class, make sure that each student gets | |
| |his or her height measured to the nearest centimeter. Record each | |
| |height on the chalkboard and on an index card. Ask pairs of | |
| |students to find the average of their two heights. Discuss how the | |
| |average is found. | |
|10 minutes |Motivation (Real-world Applications): |Calculators |
| |Take the list of heights from the Warm-up Exercise. Ask students to| |
| |first find the sum of all the heights. Then ask students to count | |
| |the number of heights recorded. | |
| | | |
| |Explain to students that the sum divided by the total number | |
| |results in the mean or average value of all the data in the set. | |
| | | |
| |Encourage students to think of when they might need to find the | |
| |mean of data in the real world. | |
|15 minutes |Presentation of New Material: |PowerPoint Presentation, slides 2–6 |
| |Explain that there are three common measures of central tendency. | |
| |As you work through the presentation for this lesson, emphasize the| |
| |difference between mean, median, and mode. Explain how to find the | |
| |median of an even number of data. Emphasize that the range is a | |
| |measure of the spread of data. | |
|10 minutes |Guided Practice: | |
| |Have students work in pairs. Have pairs calculate the mean, median,| |
| |mode, and range of the heights of the students in your class. | |
|10 minutes |Independent Practice: |Copies of the Study Island Worksheet on Central Tendency |
| |Have students work to complete the Study Island Worksheet on | |
| |Central Tendency. | |
|10 minutes |Closing Activities: | |
| |Ask the students in your class to line up from shortest to tallest.| |
| |They should hold their index card on which is written their height | |
| |in centimeters. Locate the median and mode data values. Determine | |
| |if the median they calculated is in fact the middle student | |
| |standing in line. | |
|Homework: Students should finish the Study Island Worksheet on Central Tendency. |
|Differentiation: Have students needing extra support collect five different books from the classroom and look at the page number on the last page. Have them write |
|down the five values, and help them determine the mean, median, mode, and range. Encourage students to restate the different measures of central tendency in their |
|own words. Students needing an additional challenge may be assigned to find the mean, median, mode, and range of their test scores. |
