Unit 3, Lesson 15
Situaciones de división de fracciones
Grado 5
Preparation
Lesson Narrative
In previous lessons, students learned how to divide a whole number by a unit fraction and a unit fraction by a whole number. They reasoned about relationships between dividends, divisors, and quotients. In this lesson, students apply what they have learned in this section to write and solve problems involving division of a whole number by a unit fraction and division of a unit fraction by a whole number. Before they solve the problems, students match each situation to an equation. As students match each problem with an equation, they interpret the meaning of the equation in a context (MP2).

- Generate (in writing) a situation to represent a division expression with a whole number and a unit fraction.
- Match (orally and in writing) situations and expressions that represent a whole number divided by a unit fraction.
- Escribamos situaciones y resolvamos problemas en los que se dividen números enteros y fracciones unitarias.
