1. Rounding Numbers

2. What’s the Golden Rule?

3. If the digit is five or more, around up.
For example: 36 would become 40.

4. If the digit is less than 5, you round down.
For example: 23 would become 20.

5. Here are more examples.
56 becomes 60
98 becomes 100
14 becomes 10

6. What about bigger numbers?

7. Round 154 to the nearest tens.

8. First, underline the digit in the tens place.
154

9. Next, look at the digit to the right.
154

10. If it is less than 5, the tens digit stays the same and the ones digit becomes a 0.

11. What if the number was 178?

12. Follow the same rule.
178

13. The 7 in the tens place becomes an 8
The 7 in the tens place becomes an 8. The 8 in the ones place becomes a 0.

14. So 178 becomes 180.
