General Lesson Information
 Lesson Plan ID: 26292 Title: The Laws of Exponents Overview/Annotation: During this activity, students will review the laws of exponents.  They will demonstrate their knowledge by creating an interactive computer game or a podcast.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
Associated Standards and Objectives
Content Standard(s):
 Technology Education TC2 (2009) Grade: 6-8 2 ) Publish digital products that communicate curriculum concepts. Examples: Web pages, videos, podcasts, multimedia presentations Mathematics MA2015 (2015) Grade: 6 12 ) Write and evaluate numerical expressions involving whole-number exponents. [6-EE1] Mathematics MA2015 (2015) Grade: 8 3 ) Know and apply the properties of integer exponents to generate equivalent numerical expressions. [8-EE1] Example: 32 x 3-5 = 3-3 = 1/33 = 1/27.

Local/National Standards:

NCTM Numbers and Operations 6-8

• develop an understanding of large numbers and recognize and appropriately use exponential, scientific, and calculator notation

Primary Learning Objective(s):

Students will be able to apply the laws of exponents.

Preparation Information
 Total Duration: 61 to 90 Minutes Materials and Resources: Paper and pencil Technology Resources Needed: Computers with Internet access for all students, LCD project, presentation software, and audio editing software like Audacity or Garageband (Audacity is available for free at http://audacity.sourceforge.net/.), and microphones Background/Preparation: Teachers need to understand the laws of exponents.  Teachers need to be familiar with presentation software and podcasts. Before beginning the assignment, the teacher needs to pair up the students.
Procedures/Activities:
 Review the laws of exponents with the class by showing the video clip and by using the review slide presentation. Students will decide if they are going to make a podcast review of the law of exponents or create a game.  As a resource for the laws of exponents, students can use the online resource. Students making a podcasts can watch the video explaining how to make a podcast.  Students need to include all the laws of exponents and explain how each law works.  They should include a practice problem with each law. Students making a review game can use the online game templates and pick any one of the games to create their presentation.  To create a review game students will need create practice problems applying the laws of exponents and questions about the law of exponents.  After each pair has created their review resource, students will share it with the class in a museum style setup. Students will setup their presentations around the room, so students can rotate from review presentation to review presentation.  Allow students to spend about 5 minutes at each review presentation.
