Lesson 15
Hagamos diagramas de puntos
Lesson Purpose
Lesson Narrative
In an earlier lesson, students learned about the features of a line plot. They interpreted a line plot that represented data from measurements they made in inches.
In this lesson, students measure the lengths of pencils in centimeters and represent the data on their own in a line plot. In Activity 2, students make sense of line plots that do not start at 0. They choose an appropriate starting and ending number based on the data (MP6). In the lesson synthesis, students interpret the data presented in a line plot with a scale that does not start at 0.
