`Mean, Median, Mode, etc.Charlotte Goldwater            Kenwood Academy                               5015 S. Blackstone                                Chicago IL 60615                               (312)535-1409Objectives:     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 graphMaterials 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 calculatorStrategy:     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.`
