Unit 2, Lesson 16
Estimemos productos (Optional)
Grado 5
Preparation
Lesson Purpose
The purpose of this lesson is for students to reason about the value of the product of a whole number and a fraction greater than 1 and use the properties of operations to find the product.
Lesson Narrative
In previous lessons, students represented the decomposition of a rectangle with diagrams, expressions, and equations and found the product of a whole number and a fraction.
In this optional lesson, students will practice multiplying fractions by using their understanding of the properties of operations. This time, they will not be provided with a diagram to represent each product. Students will also apply what they have learned about multiplying fractions to reason about the proximity of fractional areas to whole number areas.
- Representation
