Add U.S. Coin Values Rather Than Coin Counts

Supplied materials

• Paper and a pencil; drawing and spoken explanations are welcome. An adult may read directions and options aloud.
• Supplied worked-case record: Three dimes, two nickels, and four pennies have value 30+10+4=44 cents.
• All quantities and shape descriptions are supplied in the worked example and questions; no purchase or personal information is needed.

Learn the idea

U.S. pennies are worth one cent, nickels five, dimes ten, and quarters twenty-five. Coins have different values, so the number of coins is not the number of cents. Group matching coins, multiply each group count by its coin value, and add the group values.

Write the supplied quantity of each coin beside its value in cents. Find each group’s value and combine them. Use the cents symbol or the word cents so that a result is not confused with dollars.

Write each coin’s cents value before adding. Coin count and cents value are different quantities. Draw labeled coin groups and write a subtotal beside each type.

1. Draw labeled coin groups and write a subtotal beside each type.
2. Follow the worked example. Point to each number or shape feature and say what it tells you.
3. Write the supplied quantity of each coin beside its value in cents.
4. Try the question and then the three practice questions. Check your answers and explain any change you make.
