📚 Making Change vs. Counting Coins: What's the Difference?
Okay, imagine you're at the store. Sometimes you need to make change because you don't have the exact amount. Other times, you just want to know how much money you have. These are two different things!
🪙 Definition of Counting Coins
Counting coins is all about finding the total value of the coins you have. You're adding up the value of each coin to get one big number.
- 💰 You have a pile of coins: pennies, nickels, dimes, and quarters.
- 🔢 You count each coin and add up their values. For example, 1 quarter (25¢) + 2 dimes (20¢) + 1 nickel (5¢) + 3 pennies (3¢) = 53¢.
- ✅ The final number tells you the total amount of money you have.
💱 Definition of Making Change
Making change is when you give someone money (usually more than the item costs), and they give you back the difference.
- 🛒 You want to buy something that costs 75¢.
- 💵 You give the cashier $1.00 (which is 100¢).
- 🔄 The cashier gives you back 25¢ as change (because 100¢ - 75¢ = 25¢).
