Christmas time is just around the corner and it is time to start shopping for your mom, dad, 10 year old brother, and 6 year old sister.
You and your twin have decided to buy these presents together, since you can buy nicer presents.

Task

You will work with a partner, pretending you are twins.

All together you have $70.00 that you can spend for your Christmas presents. You and your twin have decided to spend $20 on Dad, $20 on Mom, $15 on your brother, and $15 on your sister. Each of your family members has a different favorite store.
Your grandmother has agreed to take you both shopping at all 4 of these stores, but she only has a few hours to spend. She has asked you to go on line to each of these stores and choose a gift within your price range ahead of time. After you choose each gift, she wants you to figure out how much change you should get at each store. She wants you to show her three different combinations of bills and/or coins that the cashier might give you.

Process

First, the teacher will assign you to a partner.
Then you must look at the websites you have been given and decide what items you will buy for each of your family members. Remember: $20 for Dad, $20 for Mom, $15 for Brother and $15 for Sister.
Then you need to figure out how much change you should get back at each store.
Then you need to show three different combinations of bills and/or coins that the cashier might give you.
Use your worksheet to record all of this information.
Once you have finished the above items, you should share with the whole class.
