Unit 7, Lesson 3
Dividing Powers of 10
Accelerated 7
Preparation
Lesson Narrative
In this lesson, students continue to make use of repeated reasoning to discover the exponent rule
Students begin by examining different ways to write fractions that are equivalent to 1. Next, they expand expressions written as the division of two powers of 10 and notice patterns when asked to write the quotient using a single power of 10 (MP8).
Students extend this rule to see what happens when dividing by a value with an exponent of 0. They notice that the original value remains unchanged, helping students to make sense of why
- Generalize a process for dividing powers of 10, and justify (orally and in writing) that
.
