Lesson 14
¿Qué tiene sentido en este problema?
Lesson Purpose
The purpose of this lesson is for students to consider quantities and questions that make sense in situations and solve problems accordingly.
Lesson Narrative
In earlier lessons, students encountered and solved problems about time and liquid volume. In this lesson, students model with mathematics (MP4) as they determine quantities, questions, and solutions that make sense in given situations and adhere to mathematical and real-world constraints when solving problems.
