This Instructional Activity is a part of the Lesson 1, Unit 7, Grade 8. The broken coin prompts students to think about repeated division, laying the foundation for later work on negative exponents. Understanding repeated division by 2 as being equivalent to repeated multiplication by 1/2 will later allow students to make sense of negative exponents.
