Mini Lesson
When you pay more than the price of an item, the seller gives you back the extra money. That extra money is called change. To find the change, we subtract the price from the amount we paid.
Change formula
- Change = Amount paid − Price
- Example: Pay 10¢, price is 6¢ → 10 − 6 = 4¢ change
Count-up strategy
- Start at the price.
- Count up until you reach what you paid.
- How many steps you counted = the change.
- Example: price 6¢, paid 10¢ → count 7, 8, 9, 10 = 4 steps = 4¢
Check your answer
- Price + Change = Amount paid
- 6¢ + 4¢ = 10¢ ✓
Zero change
- If the price equals what you pay, change = 0¢.
- 10 − 10 = 0
💡
Always check: price + change = 10¢. If it works, your change is correct!
