This Instructional Activity is a part of the Lesson 4, Unit 6, Grade 7. This activity is a continuation of the previous one. Students match each situation from the previous activity with an equation, solve the equation by any method that makes sense to them, and interpret the meaning of the solution. Students are still using any method that makes sense to them to reason about a solution. In later lessons, a hanger diagram representation will be used to justify more efficient methods for solving. For example, when they are using tape diagrams, they could just say "I subtracted the 9 extra markers and then divided the remaining 21 markers by 7."
