Unit 7, Lesson 7
Practice with Rational Bases
Grade 8
Preparation
Lesson Narrative
In this lesson, students practice all of the exponent rules they have learned so far and begin to look at expressions with multiple bases. Students begin by comparing four expressions using various bases, exponents, and properties of exponents. Then students investigate different ways of writing expressions that involve exponents. They also analyze the structure of exponents to make sense of expressions with different bases (MP7).
- Identify (orally and in writing) misapplications of exponent rules to expressions with multiple bases.
- Use exponent rules to rewrite exponential equations involving negative exponents to have a single positive exponent, and explain (orally) the strategy.
Let's practice with exponents.
