Lesson 5
Representemos datos en gráficas de barras con escala
Lesson Purpose
The purpose of this lesson is for students to create a scaled bar graph.
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 that, at the end of the lesson, they will be asked to identify specific examples of norms they experienced as they did math.
