Lesson 7
Answer Questions about Scaled Bar Graphs
Lesson Purpose
The purpose of this lesson is for students to solve one-step “how many more” and “how many fewer” problems based on data presented in a scaled bar graph.
Lesson Narrative
In grade 2, students solved simple Put Together, Take Apart, and Compare problems using data represented in a single-unit scaled bar graph.
In this lesson, students solve one-step Compare problems using data represented in scaled bar graphs.
