# Making Cents

### Summary

Students will play a game in which they create monetary amounts using different coin combinations.

### Coin Type(s)

- Cent
- Nickel
- Dime
- Quarter

### Coin Program(s)

- Generic

### Objectives

- Students will work cooperatively in small groups.
- Students will add coins to equal a specified amount.
- Students will understand that a certain value can be reached through the use of different sets of coins.

### Major Subject Area Connections

- Math

### Grades

- Kindergarten
- First grade
- Second grade

### Class Time

**Sessions**: One

**Session Length**:
20-30 minutes

**Total Length**:
0-45 minutes

### Groupings

- Whole group
- Small groups

### Terms and Concepts

- Coins
- Comprehension
- Logical reasoning
- Math fames
- Number sense
- Patterns
- Problem solving

### Materials

Enough circulating coins for each group of three students (plus the teacher) to have their own piles of coins. Each pile should have the same number of coins (for example, 10 pennies, 6 nickels, 6 dimes, and 4 quarters...$2 total).

- Divide the class into groups of 3 students.
- Explain the game instructions to your students.
- The game begins when you write a coin amount for all the students to see. You then select coins out of the “teacher’s pile” that equal the displayed amount, but keep them covered.
- You assign one group member to each role of counter, checker, or announcer for the group. These roles rotate at the start of each new round.
- Each group has one minute to find a way to represent the coin amount using only the coins in the pile. After the minute is over, the announcer from each group reports back to the class what coin combination was used to reach the displayed amount.
- Each group gets one point for being accurate with its coin combination. After you reveal the combination you used, an additional point goes to those groups whose choice of coins matched yours.

- Distribute a set of coins to each group of students. Each group should have the same number of pennies, nickels, dimes and quarters. You will also have the same number of coins in the "teacher's pile"—for example: 10 pennies, 6 nickels, 6 dimes, and 4 quarters ($2 total).
- Play the game for as long or as short as you like!

### Differentiated Learning Options

To extend this game for more advanced learners, invite the students to create multiple coin combinations for the same amount. Award an additonal point for each additional coin combination a student develops.

### Enrichments/Extensions

To extend this game for more advanced learners, invite the students to create multiple coin combinations for the same amount. Award an additonal point for each additional coin combination a student develops.

Observe to see who seemed to have difficulty in adding up coins and who accomplished the task with ease. (In the process of play, students will see that there are many possible solutions to putting coins together to equal a specified amount. Equaling the teacher's choice is guesswork--random choice within a possible set--but accuracy counts for a point as well.)
