Lesson 12

Ways to Represent Measurement Situations

Lesson Purpose

The purpose of this lesson is for students to make sense of situations involving measurements, interpret representations of the situations, and ask and answer questions about them.

Lesson Narrative

In previous lessons, students estimated and measured weights and liquid volumes. They learned a variety of methods and representations to solve problems involving all four operations, and used representations that made sense to them.

In this lesson, students make sense of tape diagrams (MP2), which better represent the continuous nature of measurement contexts. The context of a fair is used in this lesson and subsequent ones.
