You will use subtraction to determine the new cost of an item when a coupon is presented. You will determine if using coupons save shoppers a significant amount of money.

Role- There are several roles you will have in this assignment. You will be a shopper, who will have a starting amount of money and much purchase food to fit in your budget. You will be a calculator, who adds up the prices of groceries and subtracts any coupons used. You will be a cashier, responsible for counting back change to the customer.

Audience- You will be reporting your results on the importance of using coupons to your parents in an effort to save them money and time when going grocery shopping.

Situation- Every Sunday morning, your parents receive the newspaper filled with coupons. It seems as though there are lots of good deals and ways to save money. Nonetheless, by the time your parents look through all the aids and find items that they purchase and cut the coupons out they have wasted an hour or more. Your job is to determine if the time spent cutting and finding coupons is really worth it. Blue shoppers will shop in the classroom grocery store and use coupons to purchase their items. Red shoppers will shop in the store and not use coupons to purchase their items. Red and blue shoppers will create a graph to show their results. Students will be able to see if shopping with coupons can save them money.

Product/Performance- You will keep a chart of how much your items cost and if you use coupons. You will keep track of how much was saved by using coupons. You will work cooperatively with the other students in the class by taking turns and rotating jobs.
