A2.A.2.4 Rewrite expressions involving radicals and rational exponents using the properties of exponents.

In a Nutshell

Students will confidently rewrite radical expressions as rational exponents and vice versa.

Student Actions	Teacher Actions
Students will develop a conceptual understanding of exponents and their operations and will develop an understanding of the application of those operations to rational exponents. Students will develop accurate procedural fluency for the algorithm for converting exponential expressions to radical expressions and vice versa.	Pose purposeful questions that build on their knowledge of exponents, but do not overtake or funnel, student thinking. Implement tasks that provide students with opportunities for converting between radicals and rational exponents.
Key Understandings	Misconceptions
Apply knowledge of the relationship between rational exponents and radicals to convert between the two forms confidently. Understand that rational exponents are equivalent to radicals, written in a different form.	Students mistake a number raised to power and then a root as different than a number taken to a root raised to a power (ex is equivalent to Students will place the root in the numerator when converting from a radical to a rational exponent. Students do not recognize that rational exponents are equivalent to radicals and can be rewritten to either form.
