ATERIALS CHECKLIST:

Multiple computers; printer

Software: word processing, compatible graphing

Overhead projector with teacherprepared transparencies

Packages of M&M candies (both plain and peanut)
TIME REQUIRED: 4 class periods
ACTIVITIES AND PROCEDURES:


Have the students work in groups to count the different colors of M&M's
in each kind of package and then draw a pictograph to show the results.

Have each group write a program to show their results and then compare the
manuallydrawn and computer graphs.

Discuss with the class the differences in and results of the two methods.

Brainstorm with the class to identify data to graph (favorite pizza, sports,
musical groups, pets).

Have the student groups use the word processing software to create a survey.
Have them print copies and administer it to the class, then tabulate results
on a chart.

Teach "Range," "Mode," "Median," and "Mean" concepts. Have each group put
their survey results on the board for others to copy. Have the students find
the range, mode, median, and mean for each survey.

Have the groups create a database with the data and display the data as a
pie, bar, and line graph.
