This Instructional Activity is a part of the Lesson 10, Unit 4, Grade 8. In this activity, students focus on a context involving coins and use multiple representations to think about the context in different ways. The goal of this activity is not for students to write equations or learn the language "system of equations," but rather investigate the mathematical structure with two stated facts using familiar representations and context while reasoning about what must be true.
