In this lesson, students use line plots to solve multi-step problems about the data presented in line plots. They add and subtract fractions and work together to solve problems about data, using the Information Gap routine. All data for the line plots can 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.

This lesson has a Student Section Summary.

As you finish up this section, reflect on the norms and activities that have supported each student in learning math. List the ways you have seen each student grow as a young mathematician throughout this work. List the ways you have seen yourself grow as a teacher. What will you continue to do and what will you improve on in the next section?
