- If the digit is 5 or more (5, 6, 7, 8, or 9), you round up. This means you increase the digit in the rounding place by one.
- If the digit is 4 or less (0, 1, 2, 3, or 4), you round down. This means the digit in the rounding place stays the same.
All digits to the right of the rounding place become zeros.

8. What is the link between place value and rounding numbers?
Place value is the most important foundational concept for understanding how to round numbers. To round a number correctly, a student must first be able to identify the digit in the correct place.
- To round to the nearest 10, you must identify the digit in the ones place.
- To round to the nearest 100, you must identify the digit in the tens place.
- To round to the nearest 1000, you must identify the digit in the hundreds place.
Without a strong grasp of place value, it is difficult to apply the rules of rounding.
