Preparation
Lesson Purpose
The purpose of this lesson is for students to represent and solve two-step word problems using the four operations.
Lesson Narrative
Previously, students have represented and solved two-step word problems using addition, subtraction, multiplication, and division with smaller numbers. In this lesson, students continue to deepen their understanding of two-step word problems as they consider what they need to know to solve problems and think about the relationship between numbers in a problem. Students write equations with a letter standing for the unknown quantity to represent these problems.
