**Mean, Median, Mode, etc.**

**Objectives**:

The main objective of this mini-teach is to have students in grades four to

twelve generate their own data and then analyze their information.

Some of the ideas that could be taught are:

mean, mode, and median

histogram

bar graph

probability

circle graph

**Materials Needed**:

A piece of ribbon or rope that is at least 20 inches long

A package of post-its or a bunch of little squares of paper about 1.5"x1.5"

or 2" x 2"

A roll of masking tape

A classroom set of M&M candy bags

A wall or blackboard

A calculator

**Strategy**:

Hold up a piece of rope or string. Have the students write down the length

of this rope or ribbon on their piece of paper. Then have a number line on the

board. Have the students come up to the board and place their estimates on the

board with their post-its on the number line.

Depending on the level of the students, you could teach or introduce an

appropriate lesson on analyzing the data from a simple bar graph, quartiles, box

and whiskers, outliers, to standard deviation.

This demonstration could also be done by guessing the number of M&M's in a

cup. The results would be similar.

Lower grade students could do circle graphs of the contents of individual

bags.

**Performance Assessment**:

I can tell how much students have mastered these concepts through a

discussion or a written evaluation.
