Unit 6, Lesson 12
Maneras de representar situaciones de medidas
Grado 3
Preparation
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.
- Démosle sentido y representemos situaciones de medidas en una feria.
Required Materials
Activity 1
Required Preparation
- 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?
