Lesson 15

Hagamos diagramas de puntos

Lesson Purpose

The purpose of this lesson is for students to create line plots to represent numerical data.

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.

Teacher Reflection Questions

What did you say, do, or ask to support students in creating a line plot based on an understanding of the representation, rather than following a procedure?

Suggested Centers
