Day 2: Using local newspapers from Sunday, look through the ads and compare prices from two to three
different places, such as Target, WalMart, Meijers, and local grocery stores. Create a chart to show the
similarities and differences of costs of at least five products. Day 3: Read the article "Arts and Entertainment" from the 'comparing prices' site.
This article is about how comparing prices help people win on the Price is Right Show. After their
reading, students fill out a Pro & Cons sheet about a vacation situation. The situation is as follows:
You're going to need a bicycle for your three-week vacation at the beach. Renting a bike costs $47.00
per week. Buying the same bike would cost you $160. Calculate which option is more expensive, then fill
in the chart to help you make your decision. ARTS and ENTERTAINMENT:
How good are you at comparison shopping? If you are really good, you may be eligible to win
thousands in cash and valuable prizes on a game show! (or, at the very least, you will be eligible once
you turn 18.)
If you’re in Southern California you
might want to try out for the Price is Right.
This staple of daytime TV has been on the
air since the 1960s, making it the longest
running game show in the history of
American television.
If you make it to the show’s
“Contestants’ Row,” you’ll be asked to
name the retail prices of various products.
If you succeed, you’ll get a chance to play
one of the show’s famous pricing games.
For instance, you might be shown two items, with a price tag attached to each, and asked to
guess which one offers the biggest discount. Or, you might have to match the digits in the price of a
grocery item with the digits in the price of a car.
If you’re extra-lucky, you’ll get to spin a giant wheel and guess the price of a “showcase” filled
with big-ticket items. Woo hoo!

plus 25 cents per minute over 300. For this problem, assume that you talk an average of 500
minutes each month. Day 5: Students will take the ten question quiz which goes with the video "Comparing Prices". Together
in class, I will show the video clip "Comparing prices" one more time. Students will be asked to take out
any notes from the previous four days which they have taken. After viewing the video clip once again, I
will hand out the ten question quiz.
