Lesson Plan: Stem-and-Leaf Plots Mathematics

Start Practising

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use a stem-and-leaf plot to organize data sets.

Objectives

Students will be able to

construct a stem-and-leaf plot from a given data set, with stems of varying numbers of digits and/or decimal portions of the original data values,
analyze and interpret data given as a stem-and-leaf plot,
understand how to determine the total number of values in a given stem-and-leaf plot by counting the leaves.

Prerequisites

Students should already be familiar with

data sets,
writing data values from least to greatest and from greatest to least.

Exclusions

Students will not cover

averages or ranges of data in a stem-and-leaf plot,
back-to-back stem-and-leaf plots,
other statistical diagrams, for example, pie charts.
