This Problem Set is a part of the Lesson 17, Unit 2, Grade 7. In this lesson, students relate their algebraic steps in solving an equation to the steps they take to arrive at the solution arithmetically. They refer back to the use of tape diagrams to conceptually understand the algebraic steps taken to solve an equation. Students use tape diagrams to solve equations and translate word problems to write and solve algebraic equations using tape diagrams to model the steps they record algebraically.
