Lesson 15
Problem Solving with Line Plots
Lesson Purpose
Lesson Narrative
In this lesson, students use line plots to solve multistep problems about the data presented in line plots. They add and subtract fractions and work together to solve problems about data using the Info Gap routine. The data for line plots can all be expressed using eighths, making the arithmetic accessible with the challenge being on partner communication to share the information needed to solve the problems. The second optional activity also uses data from a line plot and here students relate repeated addition of fractions to multiplication and estimate the sum of all of the data presented in the line plot.
