## Basics on the topicAdding Coins

Your parents gave you their wallet so you can buy yourself ice cream. But how many coins do you need for one scoop of ice cream? Let’s learn more about counting coins and how to count coins for beginners with the following explanation. At the end, don’t miss out on the counting coins interactive exercises, worksheets and more activities for 2nd grade.

## Coins – A Review

Remember, coins are little, flat, circular pieces of money made from metal. When counting mixed coins, it is important to remember that each coin has a different face, a different size, and a different value. When counting American coins, they are usually worth cents, or less than a dollar. We use THIS symbol, which looks like a “c” with a line through it, it represents cents.

The values of US coins are as follows:

Coin Worth
1 penny 1 cents
1 nickel 5 cents
1 dime 10 cents
1 quarter 25 cents

To review how to teach coins to second graders, let’s start with an example to model. There are several strategies for counting coins. Let's use the coins below (one penny, one dime, two quarters, and three nickels) to review this strategy for counting coins. First, order the coins from greatest to least by writing the value of each one below it.

The order will be two quarters at twenty five cents each, one dime at ten cents, three nickels at five cents each and one penny at one cent.

Next, set up an equation by adding all the values together.

Then, solve the equation by adding up the values.

Finally, put a cent symbol next to the answer since this represents money.

## Counting Coins – Summary of Steps

Remember to follow these steps when counting coins:

Step # What to do
1 Order them from greatest to least

the values of each coin together.
3 Solve by totaling the values.
4 Don't forget to write the cent

• ### Identify the coins.

Hints

A coin's name is what we call the coin. A coin's value is how much it is worth.

The faces, size and color of a coin can help us identify which coin it is.

Solution

Look at the faces, size, and color of the coins to remember their names. Here are the values of USA coins:

• Penny = 1₵
• Nickel = 5₵
• Dime = 10₵
• Quarter = 25₵

• ### Tick the coins that are ordered correctly.

Hints

Remember to put all your coins in a straight line and pair matching coins.

The coins should be in order from largest to smallest. Put the value of each coin under the coin.

This image shows the coins in order from smallest to largest.

Solution

The image above shows the correct order of Freddie's and Zuri's coins. The correct order starts with the largest coins and ends with the smallest coins.

Zuri's coins: quarter, quarter, dime, nickel, penny, penny

Freddie's coins: quarter, quarter, dime, nickel, nickel, penny, penny

• ### Count the coins.

Hints

Remember the value of each coin and write the value underneath the coins in the problem.

Solution

Use the above image to see an example of how to count these coins.

• The first set of coins total to 73¢ (25+25+10+5+5+1+1+1)
• The second set of coins total to 51¢ (25+10+10+5+1)
• The third set of coins total to 65¢ (25+10+10+10+10)
• The fourth set of coins total to 91¢ (shown above).

• ### Compare the coins.

Hints

When comparing use the symbols > (greater than), < (less than), or = (equal to).

The open section should face the larger number. For example, 10 > 7 or 4 < 9.

Solution

Row 1 shows 26¢ is greater than 11¢

Row 2 shows 25¢ is equal to 25¢

Row 3 shows 20¢ is greater than 12¢

Row 4 shows 15¢ is less than 35¢

• ### Count the coins.

Hints

Use this image to help you order and count the coins above.

After ordering the coins, create an addition equation with the values.

Solution

The image above shows the coins in order from largest to smallest and the values underneath. After ordering the coins, create an addition equation with the values. This set's equation should be:

• 25 + 25 + 10 + 10 + 5 + 5 + 1 + 1 + 1 = 83₵

• ### Chose the correct amount of coins.

Hints

Use the value of each coin to help you count them up.

Think of how many 10s, 5s and 1s you can use to make 61.

Solution

Another way to make 61¢ without quarters is using:

• 5 dimes = 50¢
• 2 nickels = 10¢
• 1 penny = 1¢
Together make 61¢
