How many coins equal one dollar? Grade 2 math explained

📚 Understanding the Value of Coins

Before we figure out how many coins make a dollar, let's quickly review the value of each coin:

• 🪙 Penny: A penny is worth 1 cent.
• 🪙 Nickel: A nickel is worth 5 cents.
• 🪙 Dime: A dime is worth 10 cents.
• 🪙 Quarter: A quarter is worth 25 cents.

Remember, 100 cents equals one dollar ($1.00)!

🔢 Making a Dollar with Pennies

This is the easiest to understand. Since each penny is worth 1 cent, you would need 100 pennies to make a dollar.

• ✏️ 1 dollar = 100 cents
• ➕ 100 pennies x 1 cent = 100 cents
• ✅ Therefore, 100 pennies = $1.00

🪙 Making a Dollar with Nickels

Since each nickel is worth 5 cents, let's figure out how many nickels you need.

• ➗ We need to divide 100 cents (one dollar) by 5 cents (value of one nickel).
• 📝 The equation is: $100 \div 5 = 20$
• ✨ Therefore, you need 20 nickels to make a dollar.

💰 Making a Dollar with Dimes

Each dime is worth 10 cents, so let's calculate how many dimes are needed.

• ➗ Divide 100 cents by 10 cents.
• ➗ $100 \div 10 = 10$
• ✅ You need 10 dimes to make one dollar.

💵 Making a Dollar with Quarters

Now let's figure out quarters. Each quarter is worth 25 cents.

• ➗ Divide 100 cents by 25 cents.
• ➗ $100 \div 25 = 4$
• ✔️ So, you need 4 quarters to make one dollar.

🧮 Mixing Coins to Make a Dollar

You can also use a combination of different coins to make a dollar. Here are a few examples:

• 💡 2 quarters (50 cents) + 5 dimes (50 cents) = $1.00
• 💡 1 quarter (25 cents) + 7 dimes (70 cents) + 1 nickel (5 cents) = $1.00
• 💡 5 dimes (50 cents) + 10 nickels (50 cents) = $1.00
