Subject: Mathematics (9  12) Title: Exponents and Division
Description: This activity will introduce the exponent and division rule, the zero exponent rule, and the negative exponent rule. Students will make a human fraction to discover the division rule for exponents. The lesson will also introduce various interactive sites for reviewing exponent rules.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.
Subject: Mathematics (9  12), or Technology Education (9  12) Title: You Mean ANYTHING To The Zero Power Is One?
Description: This lesson is a technologybased project to reinforce concepts related to the Exponential Function. It can be used in conjunction with any textbook practice set. Construction of computer models of several Exponential Functions will promote meaningful learning rather than memorization.
