Unit 2, Lesson 8
Dividamos para multiplicar fracciones no unitarias
Grado 5
Preparation
Lesson Purpose
The purpose of this lesson is for students to represent and solve problems involving a non-unit fraction.
Lesson Narrative
In this lesson, students make sense of the product of a whole number and a non-unit fraction. Students relate the product of a whole number and a non-unit fraction to the product of a whole number and a unit fraction. They will have more opportunities to multiply a whole number by a fraction in the next section, systematically using the idea of area. This lesson continues to focus on the relationship between multiplication and division and encourages students to solve and interpret the problems in ways that make sense to them.
