Line Plots

Objectives - To draw and describe line plots; and to use landmarks of data.

1 Teaching the Lesson

Students draw line plots to represent data about themselves. Then they determine which of their "mystery plots" represents which information. They also identify landmarks of the data - minimum, maximum, median, mode, and range - for each line plot. [Data and Chance]

3 Options for Individualizing

Enrichment - Students create and analyze mystery line plots [Data and Chance]

Background Information

Advance Preparation - Divide the class into five groups for the mystery plot activity in Part 1. You will need one envelope for each group. Use stick-on notes to prepare two sets of labels: 1, 2, 3, 4, and 5; and A, B, C, D, and E. Affix one letter-label to each envelope. Reserve the number-labels for later use. Write a correspondence between letters and numbers, for your eyes only; for example, A <=> 2, B <=> 4; C <=> 5, D <=> 1, E <=> 3. Each of the five groups will need one large piece of paper. Pads of chart paper or rolls of butcher paper, available from most school supply distributors, work well. Put one copy per student of Teaching Master next to the Math Message.
