Lesson 9
Interpretemos gráficas de barras
Lesson Purpose
Lesson Narrative
In previous lessons, students learned how to interpret categorical data represented in picture graphs and other displays. In this lesson, bar graphs are introduced as another way to represent categorical data. Students compare the features of bar graphs to picture graphs and use the unique features of bar graphs to interpret data and answer questions. When students relate the data to the context it represents and carefully interpret the elements of a graph, they reason abstractly and quantitatively and attend to precision (MP2, MP6).
