Lesson Purpose
The purpose of this lesson is for students to solve multiplication problems.
Lesson Narrative
Students write equations with a symbol for the unknown to represent multiplication problems and then solve the problems. As in the previous lesson, some problems are unknown factor problems, which students do not relate to division until a future unit. Students put together what they have learned about drawings, diagrams, expressions, and equations to solve multiplication problems.
