Anyone for Lunch?

Sandi Tidwell

Description

The student will use statistical methods to record and make inferences about real-world situations using graphs.

Objectives

The student solves problems by generating, collecting, organizing, displaying, and analyzing data using histograms, bar graphs, circle graphs, line graphs, pictographs, and charts.

The student designs experiments to answer class or personal questions, collects information, and interprets the results using statistics (range, mean, median, and mode) and pictographs, charts, bar graphs, circle graphs, and line graphs.

Materials

-Pencil
-Paper
-Markers
-Graph Paper
-Graphing software (Optional)

Preparations

Distribute graph paper and markers
Prepare computers if using Microsoft Excel, Graph Club, or another related software.

Procedures

1. Have each student list the different foods he/she ate for lunch that day. (This doesn't mean foods served, but actual food eaten.)

2. Call on students to share their lists, one food at a time.

3. As each food is named, have other students who ate the same food raise their hands.

4. Ask a volunteer to record that food item on the chalkboard and write the number of raised hands.

5. After a record is made of all students and all foods, have the students work cooperatively to represent the data in a bar graph.

6. Encourage students to analyze the data in their journals to answer the following questions:

    1) What is the most popular food?
    2) What is the least popular food?
    3) What food group is most popular?
    4) What food group is least popular?
    5) How could this information be helpful to lunchroom staff?

Assessments

The completed graph and math journal is used for assessment.

Suggested criteria

The point value of the criteria can be teacher discretion:

1) Information is correctly graphed.

2) Graph is neat and easy to read.

3) Journal entries are correctly and clearly answered.
