Lesson 3
Interpretemos ecuaciones
Lesson Purpose
The purpose of this lesson is for students to write equations to represent division situations and relate each part of the equation to the situation.
Lesson Narrative
In previous lessons, students developed the understanding that \(1 \div b = \frac{1}{b}\) . In this lesson, students deepen their understanding of the relationship between division and fractions. They write equations and explain how each part of the equation corresponds to a situation.
