Money: Coins, Dollar Bills & Word Problems

Learn the values of U.S. pennies, nickels, dimes, quarters, and dollar bills. Count and compare collections, make the same amount in different ways, and solve simple shopping and change problems using the $ and ¢ symbols correctly. Work through 25 fully explained examples, 30 independent practice problems, and a 15-question lesson test.

๐ŸŽฏ What You Will Learn

Recognize U.S. money

Identify a penny, nickel, dime, and quarter; know the values of $1 and $5 bills.

Count mixed coin groups

Skip-count by 25s, 10s, and 5s, then add pennies.

Make equivalent amounts

Find two different collections that have the same value and compare what you have.

Solve money word problems

Add costs, find change, and choose the correct $ or ¢ symbol without requiring decimal notation.

Common Core alignment — 2.MD.C.8. Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies using the dollar and cent symbols appropriately. This lesson builds on Grade 2 addition and subtraction within 100 and skip-counting. We use $ for whole dollar amounts and ¢ for cent amounts; amounts containing both are written, for example, $1 and 35¢ rather than in decimal notation.

๐Ÿง  Key Vocabulary

Penny and nickel

A penny is worth 1 cent (1¢); a nickel is worth 5 cents (5¢).

Dime and quarter

A dime is worth 10 cents (10¢); a quarter is worth 25 cents (25¢).

Dollar bill

A $1 bill is worth one dollar. A $5 bill is worth five dollars. One dollar equals 100 cents.

Total and change

A total is how much you have or spend altogether. Change is the money you get back after paying more than a price.

Equivalent amounts

Different groups of coins can have the same total value.

Dollar and cent symbols

Write $ before a whole-dollar amount, as in $5. Write ¢ after a cent amount, as in 45¢.

Big idea: To find the value of mixed coins, group the same coins together and count the largest values first. A coin’s physical size does not determine its value: a dime is smaller than a nickel, but it is worth more.

๐Ÿช™ 1. Meet U.S. Coins and Dollar Bills

Use the name and value of each coin, not just its size or color. U.S. coins in our drawings are simplified learning models; real coins have more detail.

CoinValueHelpful way to count
Penny1¢By ones
Nickel5¢By fives
Dime10¢By tens
Quarter25¢25, 50, 75, 100
$1 bill$1 = 100¢One whole dollar
$5 bill$5Five whole dollars
The four common U.S. coins. Their values are marked on this learning chart.
On a narrow screen, swipe sideways to see the whole diagram. With a keyboard, focus the diagram and use the arrow keys.
Remember: A quarter is 25¢, a dime is 10¢, a nickel is 5¢, and a penny is 1¢. Four quarters make 100¢, or $1.

๐Ÿ”ข 2. Count Like Coins by Their Values

Count nickels by fives, dimes by tens, and quarters by twenty-fives. For example, three nickels make 5¢ + 5¢ + 5¢ = 15¢. A penny adds 1¢ each time.

First count the three nickels, then the two dimes. Each coin has its own value.
On a narrow screen, swipe sideways to see the whole diagram. With a keyboard, focus the diagram and use the arrow keys.
Important: Five coins do not always mean 5¢. To find a total, use both the number of coins and the value of each coin.

๐Ÿงฉ 3. Count Mixed Collections

Group quarters, dimes, nickels, and pennies. Add one group at a time. For example, a quarter, two dimes, and three pennies make 25¢ + 20¢ + 3¢ = 48¢.

Look for the quarter first, then count the dimes and the pennies.
On a narrow screen, swipe sideways to see the whole diagram. With a keyboard, focus the diagram and use the arrow keys.
Watch out: Do not write $48 when you mean 48¢. The dollar symbol changes the amount.

๐Ÿ”„ 4. Find Equal Amounts in Different Ways

Different coins can have the same value. For example, two dimes are worth 20¢, and four nickels are also worth 20¢. Both are valid ways to make 20¢.

Each collection has a different number of coins but can have the same value.
On a narrow screen, swipe sideways to see the whole diagram. With a keyboard, focus the diagram and use the arrow keys.

When a question asks for one different combination, more than one answer may be correct. Explain the values of the coins you chose.

๐Ÿ’ต 5. Work with Dollar Bills and Cents

A $1 bill is worth 100¢. Two $1 bills are $2, and a $5 bill and two $1 bills are $7. At this grade level, we can write a mixed amount as $1 and 35¢, keeping dollars and cents clear without using decimal notation.

Count the whole-dollar bills first. Add cents separately when coins are also present.
On a narrow screen, swipe sideways to see the whole diagram. With a keyboard, focus the diagram and use the arrow keys.
Dollar-versus-cent check: A price of 35¢ is less than a dollar. A price of $35 means thirty-five whole dollars.

๐Ÿ›️ 6. Solve Shopping and Change Problems

Read the question carefully: Are you finding the total price, the amount left, the change, or how much more money is needed?

Total cost

Add prices in the same unit: 30¢ + 45¢ = 75¢.

Change

Subtract the price from the amount paid: 50¢ − 35¢ = 15¢.

Enough money?

Compare the money you have with the price. If it is less, find the difference.

Two-step shopping

Add two prices, then subtract from the amount you have. Explain each step.

Classroom math: Use real or play money to model a small store. All prices and coin combinations in this lesson are invented for practice.

๐Ÿ’ก Common Mistakes to Watch For

Confusing a coin’s size with its value

A dime is smaller than a nickel but is worth twice as much.

Counting coins instead of cents

Three quarters are 75¢, not 3¢.

Mixing dollars and cents

Write 48¢ for forty-eight cents, but $4 for four dollars.

Forgetting that a dollar is 100 cents

A $1 bill can pay for a 75¢ item, leaving 25¢.

Adding when asked for change

To find change, subtract the cost from the amount paid.

Assuming only one coin combination works

Four nickels and two dimes can make the same value as four dimes. Check the total.

๐Ÿก Family Practice Idea

Make a pretend store: Put labels such as 25¢, 40¢, and 65¢ on small household objects. Use safe play money or pictures of coins. Ask your learner to show two different ways to pay, decide whether 75¢ is enough, and explain any change. Reinforce the dollar sign and cent sign as you go.
