RULE IN ROUNDING NUMBERS
We round a number up if the digit we are rounding is followed by 5, 6, 7, 8, or 9.
We round a number down if the digit we are rounding is followed by 4, 3, 2, 1, or 0.
To round numbers to the nearest thousands, follow the following steps:
Label each digit with the correct place value.
Identify the digit to be rounded off.
Identify the digit found at the right side of the digit to be rounded off.
Change all the digits to the right of the number you are rounding into zero (0).
Copy the digit/digits at the left side of the digit you are rounding.
