# Stamping Coins

### Summary

Students will learn and demonstrate that they can use a variety of coin combinations to make a single amount. This lesson is part of the Unit Plan “Creative Coin Combinations.”

### Coin Type(s)

- Cent
- Nickel
- Dime
- Quarter
- Half dollar

### Coin Program(s)

- Generic

### Objectives

- Students will learn about coin equivalents.
- Students will learn all the ways to make 50 cents using different coin combinations.

### Major Subject Area Connections

- Math

### Grades

- Kindergarten
- First grade
- Second grade

### Class Time

**Sessions**: One

**Session Length**:
30-45 minutes

**Total Length**:
0-45 minutes

### Groupings

- Whole group
- Pairs

### Terms and Concepts

- Cent
- Coin equivalents
- Dime
- Half dollar
- Money
- Nickel
- Penny
- Quarter
- Representation

### Materials

- 1 large piece of paper for each student pair
- 1 paper strip or precut shape for each student pair that relates directly to the story read in the first lesson, “For Sale!” This shape should be different from the shape used in the second lesson, “Mixing Coins.”
- Real or play coins: pennies, nickels, dimes, quarters, and a half dollar for each group of students
- Glue
- Coin stamps in the same denominations as the coins

### Preparations

Cut and write amounts on the paper strips or precut shapes. They must be large enough to allow attaching multiple coin stamps to equal the total amount.

- Review with the students skip counting with coins and counting out coins to match numerical values.
- Introduce your students to the idea that they can make a single coin amount using different coin combinations. Model with your students one way to make 25 cents, and then invite students to try to make 25 cents in a different way.
- Once the students seem comfortable with this concept, divide the class into pairs. Give each pair a paper strip or shape (to glue on top of a large piece of paper), an assortment of real or play coins, and coin stamps.
- Have the students use their coins to make all possible combinations that equal 50 cents. Each time the students find a new combination, have them attach the correct coin stamps in a row on their strip or cut-out shape.

### Differentiated Learning Options

Students could also do this assignment independently or in larger groups, depending on their needs.

Evaluate the pages where the students show different ways to make 50 cents.
