# Do You Have a Coin Collection?

### Summary

After briefly discussing coin collecting, the class takes a poll to see how many students collect coins. Then students create a graph showing all responses and discuss the survey results.

• Cent
• Nickel
• Dime
• Quarter
• Half dollar
• Dollar

• Generic

### Objectives

Students will interpret displays of data and solve problems that involve collecting and analyzing data.

• Math

• Kindergarten

### Class Time

Sessions: One
Session Length: 20-30 minutes
Total Length: 0-45 minutes

• Whole group

Coins

### Materials

• A paper coin for each student
• Glue
• A graph onto which the paper coins can be glued

### Preparations

• Create a paper coin for each student in the class.
• Create a two-column graph onto which the students will glue the coins.
1. Create a paper coin for each student in the class, and a graph on to which to glue the coins.
2. Discuss coin collections and talk about the collecting hobby with your class. You might read a book about coins aloud or visit the H.I.P. Pocket Change(TM) Web site.
3. Give each student a paper coin. Then ask, "Who has a coin collection?"
4. Have those students with a coin collection come to the front of the class and glue their coins on the graph. Then have the remaining students glue their coins on the other half of the graph.
5. Ask students to look at the graph and answer these questions: How many students in our class have a coin collection? How many students in our class do not collect coins? How many more people in our class collect coins than don't? (or vice versa.) What else can you tell about the students in our room from this graph?

### Differentiated Learning Options

Have students conduct their own surveys about coin collecting with family and friends.

How well are students able to analyze the results of the class graph?
