Activity 9

Author: Sharon Hedge - Central Middle School, Hollow Rock-Bruceton Special School District.

Materials: Database software.

Description: This activity can be used for measurement in math. Have the students fill out an information sheet about themselves. Some of the questions might be:

  1. What is your weight in pounds?
  2. What is your weight in kilograms?
  3. What is your age in years?
  4. What is your age in months?
  5. What is your height in inches?
  6. What is your height in centimeters?

The data will then be entered into a database where the students will be able to analyze, compare, and report on their findings. All students will participate in each phase of the activity from collecting the data through reporting their results.


Lesson 12

Author: Robbie Carlton, Huntingdon Jr. High School, Huntingdon Special School District.

Grade Level: 7

Objectives:

  1. Measure the height of each student in the class.
  2. Record data on a spreadsheet.
  3. Compare mixed numbers (greatest to least).
  4. Find the mean, median, mode and range of a list of heights.

Materials and Equipment:

Background Information:

Vocabulary: Mean, median, mode, range.

Procedures:

  1. Each class is divided into groups of four.
  2. Each group is assigned to a measuring station. (Measurements to the nearest inch should be taped to the wall prior to the beginning of class. One per group.)
  3. Each group will record individual heights on the data page.
  4. Each group will report individual heights to the teacher to enter data on the spreadsheet.
  5. While class data are being recorded, each group will use their own individual heights to find the mean, median, mode and range for the group.
  6. Have the spreadsheet sort heights from the greatest to the least. This allows the students to see first hand the time saving factor of using a computer spreadsheet.
  7. Each group is to illustrate its data as a bar graph.
  8. Using three colors, draw a horizontal line for each value (mean, median, mode) across the graph to compare individual heights to the group.
  9. Using the graphing feature of the spreadsheet software, print out a class graph for individual heights.
  10. Compare group graphs with the class graph. Discuss the differences and similarities.
  11. Have the computer calculate the mean, median, mode and range for the class data.
  12. Compare the class mean, median, mode and range with each groupÕs values. Discuss the differences and similarities.

Additional Activities:

  1. Each student writes a report describing how his or her own height compares to the class data.
  2. Using the class data graphs for all classes, compile a graph and report that will summarize all data.
