Today, class, we are going to learn about mean, median, and mode. We are going to use the computers to learn about mean,median, and mode, but please do not turn your computers on until I ask you to. I want to show you a little about this activity first. Guided Practice Introduce and develop the concepts of mean and median with the Measures activity. Students will change parameters and discover patterns related to mean and median.
Students can choose their own focus of measure, their own quantity, and their own units.
Independent Practice Have the students either individually or in groups read and try to solve sample problems on mean, median, and mode. Closure You may wish to bring the class back together for a discussion of the findings. Once the students have been allowed to share what they found, summarize the results of the lesson. This lesson introduced the students to some basic ways of describing sets of data. The next lesson, Histograms and Bar Graphs , introduces histograms, bar graphs and the concept of class interval.
