Negative Exponents (Guided Notes)
- Word Document File
What educators are saying
Description
This lesson is meant to be used as guided notes for a whole class.
Students begin by learning the rule for negative exponents, followed by a simple proof/explanation of why. After learning that 1 raised to any number equals 1, they begin working with negative exponents. They are shown how to rewrite negative exponent expressions with positive exponents, and vice versa. Next, they are challenged to rewrite fractions as expressions with negative exponents. For example, they see how to rewrite 1/25 as 5^-2. Finally, they evaluate variable expressions that involve negative exponents.
*This lesson is definitely an intro to negative exponents. The problems are not very complicated. For example, students will not be simplifying things like [(-3xy^-5)^-4]/(5x^-8). This lesson would probably be considered Pre-Algebra as opposed to Algebra 1 or 2.
