Students learn how to calculate the reciprocal of a number and evaluate indices with negative powers.  As learning progresses they are challenged to consider indices with negative and fractional powers.

Differentiated Learning Objectives

• All students should be able to simplify and evaluate terms written in index form where an integer base is raised to a negative power.
• Most students should be able to simplify and evaluate terms written in index form where a decimal base is raised to a negative power.
• Some students should be able to simplify and evaluate terms written in index form where the base is written as a fraction or mixed number is raised to a negative power.
