Lesson 6

La división como un factor desconocido

Lesson Purpose

The purpose of this lesson is for students to relate multiplication and division and recognize division as an unknown factor problem.

Lesson Narrative

Previously, students learned to interpret and write division expressions. They connected division to multiplication informally, recognizing that both operations involved equal groups. In this lesson, students analyze related multiplication and division equations to formalize the relationship between multiplication and division. In the lesson synthesis, students learn that the result in a division equation is called a quotient.
