Answer Questions about Scaled Bar Graphs
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.
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.
- Solve one-step “how many more” and “how many fewer” problems within 100, based on the data presented in scaled bar graphs.
- Let’s solve problems based on data represented in bar graphs.
