Unit 6, Lesson 12
Ways to Represent Measurement Situations
Grade 3
Preparation
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 measurements. The context of a fair is used in this lesson and subsequent ones.
- Engagement
- MLR8
- Ask (orally and in writing) and answer questions about real-world situations involving measurements.
- Match (orally and in writing) tape diagrams and word problems involving measurements that represent the same relationships.
- Let’s make sense of and represent measurement situations at the fair.
Required Materials
Activity 1
Required Preparation
Activity 2
- Create a set of cards from the blackline master for each group of 2.
Teacher Reflection Questions
How did you see students using their prior mathematical knowledge to solve problems involving the four operations in these new measurement contexts?
