This Instructional Activity is a part of the Lesson 5, Unit 7, Grade 8. This activity requires students to make sense of negative powers of 10 as repeated multiplication by 1/10 in order to distinguish between equivalent exponential expressions. If students have time, instruct them to write the other expressions in each table as a power of 10 with a single exponent as well. Give students 15 minutes of partner work time followed by a whole-class discussion.
