Unit 1, Lesson 5
Representemos datos en gráficas de barras con escala
Grado 3
Preparation
Lesson Narrative
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.
Math Community
Tell students they will have a chance to revise their math community ideas at the end of this lesson. As they work today, students should think about norms that may be missing from the current list
- Engagement
- MLR7
- Compare and contrast (orally and in writing) bar graphs with different scales.
- Comprehend (in spoken language) the meaning of the term “scaled bar graph.”
- Represent data using a scaled bar graph.
- Hagamos una gráfica de barras con escala.
Required Preparation
- Each student needs the picture graph they created 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?
