Purpose and Instructional Strategies

The purpose of this benchmark is for students to formally recognize the respective value of coins. (MTR.5.1, MTR.7.1)

• Instruction includes both the front and back sides of pennies, nickels, dimes and quarters.
• Instruction emphasizes that the relative size of the coin is not representative of its value in comparison to other coins. (MTR.5.1)
• Instruction uses the format 25¢, not \$0.25.

Common Misconceptions or Errors

• Students may believe the value of a coin is directly related to its size (e.g., a nickel is bigger than a dime and is worth more, or a penny is bigger than a dime, so it must also be worth more). In these cases students need additional practice identifying a coin with its actual value.

• What are the defining attributes and value of a penny? nickel? dime? quarter?
• Sample answer that demonstrates understanding: The student can identify people or landmarks on the coin along with some defining attributes (color, size, texture of sides). Such as, the sides of a dime and a quarter is bumpy/rough while the sides of a penny and nickel is smooth, a penny is the only cooper/brown colored coin, and a nickel is bigger than a dime but the dime is worth more.
• What is the most efficient way we can count a group of nickels? Dimes?
• Sample answer that demonstrates understanding: Since the value of a nickel is worth 5¢, we can count by 5s to find the value of a group of nickels. We can do the same with dimes. Since the value of a dime is worth 10¢, we can count by 10s to count a group of dimes.
• Does the size of the coin determine whether it’s worth more?
• Sample answer that demonstrates understanding: Size does not determine the value of a coin. A nickel is bigger than a dime in size but not in value.
• How can we represent 100 cents in multiple ways using like coins?
• Sample answer that demonstrates understanding: 100 pennies, 20 nickels, 10 dimes, 4 quarters.
• What symbol can we use to represent the word cent?
• Sample answer that demonstrates understanding: ¢

Part A. Using the table below, identify each coin’s name and its value.

Part B. What is the total value of the coins on the table?

Part C. With a partner, compare your value column and discuss if you both came up with the same total. What could you do to figure out who is right or check your work for accuracy?
