   Pause here so your teacher can review your work.

2. We can say that “1 percent of the large square” is shaded in Diagram A and “15 percent of the large square” is shaded in Diagram B.

   Shade 50 percent of the area of the large square.

   

Here are the names and values of some U.S. coins.

Here are some ways to describe the coins’ values using percent (%):

• The value of a dime is 10 percent of a dollar.
• The value of a quarter is 25 percent of a dollar.
• The value of 5 dimes is 50 percent of a dollar.

1. Describe the value of each coin using “percent of a dollar.”

   1. A penny

   2. A nickel

   3. A half dollar

   4. A dollar

2. Jada has two coin collections. Each collection has the same type of coins.

   1. Her first collection of coins is worth 105 percent of a dollar. What is the value of this collection?
   2. Her second collection of coins is worth \$2.00. What percent of a dollar is that?
3. Write a definition for “percent” based on your understanding now.

Double number line diagrams can help us think about percentages.

1. Here is a diagram that can represent the value of money as a percentage of a dollar.

   

   1. The value of 2 quarters is 50 percent of a dollar. How can you see that in the diagram?
   2. Label the diagram to show the values of 1 quarter and 3 quarters. What percent are they of a dollar?
2. For each question, use the double number line diagram to show your reasoning.

   1. Clare has 6 dimes in her pocket. What percentage of a dollar does she have?

      

   2. Han has 6 quarters in his pocket. What percentage of a dollar does he have?

      

   3. Which has a greater value: 8 nickels or 40% of a dollar?
