Represent Data in Scaled Bar Graphs
The purpose of this lesson is for students to create a scaled bar graph.
In a previous lesson, students collected categorical class data and learned how to create a scaled picture graph. Students now make connections between scaled picture graphs and scaled bar graphs, and expand the idea of a scale that is more than one to bar graphs. In this lesson students choose a scale of 2 or 5 for their bar graph.
Tell students that, at the end of the lesson, they will be asked to identify specific examples of norms they experienced as they did math.
- Represent data using scaled bar graphs.
- Let’s make a scaled bar graph.
Materials to Gather
- Each student needs the picture graph they creaed in the previous lesson.

Teacher Reflection Questions
Based on students’ prior work with scaled picture graphs, what strategy did you anticipate today? What strategy did you not anticipate?
- Sort and Display (1–3), Stage 3: Scaled Graphs (Addressing)
- Five in a Row: Addition and Subtraction (1–2), Stage 6: Add within 100 with Composing (Supporting)
