- Coins
- Money
- Nickel
- Penny
- Value

### Materials

For each student:

- 1 mint or cough drop tin containing 10 pennies and 5 nickels (real) for each student
- Large paper coins
- Large paper coin holder
- 25 envelopes with change amounts written on them

- Place a pile of mixed coins (pennies and nickels) where all the students can see them. Ask the students several questions to initiate conversation.
- What is this? (a pile of coins)
- How much money is in the pile? How can I find out how much money is in the pile?
- Do I count the number of coins, or is there something else I need to know about the coins to find out how much money I have? (You need to know the value of each coin and add the values together.)

- Review the two coins you will be working with (penny and nickel). How much are they each worth? Which is worth more?
- Review the rules of using coin boxes given in the lesson "An Introduction to Coins" with your students.
- Give each student a coin box. Have them add the values of their coins.
- How much money do I have if I have one penny and find three more?
- How much money do I have if I have a nickel and three pennies?

- Divide the class into pairs. Distribute an envelope to each student.
- Have the students use their coins to put the specific amount of money written on the front of their envelopes into the envelopes.
- Have the students trade envelopes with their partner, then check their partner's coins to make sure that the amount is correct.
- Have each student put coins in their partner's envelop that add up to the amount written on it, but using a different coin combination than their partner used.
- Have the partners trade envelopes again and check the partner's work.
- Have the students empty the envelopes, then trade envelopes with someone besides their partner so each student has a new, empty envelope. Have them repeat steps 6 through 9 with the new envelopes.
- Have all the students return their coins to their boxes. Collect the boxes.
- Invite students to come to the front of the room to illustrate two ways of producing the same value using only the large paper pennies and nickels.
- Discuss the exercise with the class. Ask how it felt to figure out the amounts, whether it was easy or hard, and what coins they tended to exchange when they had to think of another way to express the same amount.

### Differentiated Learning Options

- Allow students extra time.
- Allow the use of charts.

Evaluate whether the students met the lesson objectives by observing the students' ability to work in pairs, follow directions, and develop different combinations of coins for the same amount. Also note how hard or easy the task was and whether they recognized that 5 pennies are worth 1 nickel.
