4.  Write a paragraph describing your best friend.  Include how you met this friend, how long you've known each other, and why you choose the CDs you did for the birthday gift.

7) Instructional Activities:

Begin this lesson by playing a song off of a CD that you think the students can identify.  Ask the students if they have ever received a CD for their birthday.  Tell the students to write down about four of their favorite CDs and to estimate how much each one would cost.   Have the class brainstorm ways in which they could verify the real cost of said CDs.  They should come up with sales ads, brochures or the Internet.  Show the students ads, brochures to music clubs or log onto the URL for any store that sales CDs, such as http://www.kmart.com .  Show the students that if they go under the music favorites tab that they can locate any CD or artist that the store carries.  This is one way they could find out the real cost of the CDs.  You may want to show the students how they could look up information in the sales ads and brochures to the music clubs.  Discuss the shipping and handling charges , as well as, state tax.  Once students are familiar with the various resources that they will be using to complete this assignment you may need to show some examples on the board.  Be sure examples include shipping and taxes. 

Pass out the assessment/worksheets and have volunteers read the various questions and come to the board to practice a sample chart, list or graph that will display the required information.  Allow students to get in three groups by counting off to three.  Each group will need to decide what resources their group will use to gather information to complete the assignment, either the Internet, sales ads, or brochures.  If the students seem disappointed that they did not get to use the resource that was their first choice you may want to rotate the groups until all students have done the assignment using all three types of resources. 

Remind the students of the essential questions and let them begin their work.  The criteria for scoring the assessment worksheet will be 25 points for each question and the district grading scale will determine the final grade.93-100 A, 85-92 B, 75-84 C, 70-74 D, and 0-69 F.
