This Instructional Activity is a part of the Lesson 5, Unit 4, Grade 8. The goal of this activity is for students to build fluency solving equations with variables on each side. Students describe each step in their solution process to a partner and justify how each of their changes maintains the equality of the two expressions. Look for groups solving problems in different, but efficient, ways.
