# Lesson 13

Problemas de varios pasos sobre medidas con fracciones

### Lesson Purpose

The purpose of this lesson is for students to solve multi-step problems that involve multiplicative comparison and measurement in whole numbers and fractions.

### Lesson Narrative

In earlier lessons, students learned about the relationship between pounds and ounces and solidified their understanding of how hours, minutes, and seconds are related. In this lesson, they apply these insights to solve multi-step problems, including multiplicative comparison problems. The last activity in the lesson is optional and is a complex puzzle involving pounds and ounces.
