Counting Money up to One Dollar

Counting Money up to One Dollar

When we count money, we use different coins. To find out how much money we have, we add the values of the coins together. We use the cent symbol (ยข\text{ยข}) to write our total.

Meet the Coins

Before we count, let's remember the value of each coin:

  • Penny: 1ยข1\text{ยข}
  • Nickel: 5ยข5\text{ยข}
  • Dime: 10ยข10\text{ยข}
  • Quarter: 25ยข25\text{ยข}

How to Count a Group of Coins

The best way to count a pile of coins is to start with the coins that have the highest value and work your way down to the lowest.

Example: How much is 2 quarters, 1 dime, 3 nickels, and 4 pennies?

  1. Start with the quarters: 25ยข+25ยข=50ยข25\text{ยข} + 25\text{ยข} = 50\text{ยข}
  2. Add the dime: 50ยข+10ยข=60ยข50\text{ยข} + 10\text{ยข} = 60\text{ยข}
  3. Add the nickels: Count up by fives: 65ยข,70ยข,75ยข65\text{ยข}, 70\text{ยข}, 75\text{ยข}
  4. Add the pennies: Count up by ones: 76ยข,77ยข,78ยข,79ยข76\text{ยข}, 77\text{ยข}, 78\text{ยข}, 79\text{ยข}

The total value is 79ยข79\text{ยข}.

Different Ways to Make the Same Amount

You can use different combinations of coins to make the exact same amount of money.

Example: How many ways can you make 50ยข50\text{ยข}?

  • Way 1: 2 quarters (25ยข+25ยข=50ยข25\text{ยข} + 25\text{ยข} = 50\text{ยข})
  • Way 2: 5 dimes (10ยข+10ยข+10ยข+10ยข+10ยข=50ยข10\text{ยข} + 10\text{ยข} + 10\text{ยข} + 10\text{ยข} + 10\text{ยข} = 50\text{ยข})
  • Way 3: 1 quarter, 2 dimes, and 1 nickel (25ยข+10ยข+10ยข+5ยข=50ยข25\text{ยข} + 10\text{ยข} + 10\text{ยข} + 5\text{ยข} = 50\text{ยข})

Do You Have Enough?

Sometimes you need to count your coins to see if you can buy something.

Example: You want to buy a sticker that costs 75ยข75\text{ยข}. You have 2 quarters and 3 dimes in your pocket. Do you have enough?

  • First, find your total: 2 quarters (50ยข50\text{ยข}) + 3 dimes (30ยข30\text{ยข}) = 80ยข80\text{ยข}.
  • Next, compare the amounts: 80ยข80\text{ยข} is greater than 75ยข75\text{ยข} (80>7580 > 75).
  • Yes! You have enough money to buy the sticker, and you will even get 5ยข5\text{ยข} back in change!
