Rounding Whole Numbers to any Place

This lesson teaches how to round whole numbers to any place value by examining the digit to the right of the target place. If this digit is 5 or more, the target digit is increased by one, and all digits to the right become zeros. If less than 5, the target digit remains unchanged, and all digits to the right become zeros. Examples include rounding 6,386 to the nearest hundred and 296,532 to the nearest ten thousand.

What is the first step in rounding a whole number to a specific place?

• Look at the digit to the right of the place.

• Look at the digit to the left of the place.

• Look at the digit in the hundreds place.

• Look at the digit in the place you are rounding to.

When rounding the number 6,386 to the nearest hundred, what is the rounded number?

• 6,300

• 6,400

• 6,500

• 6,380

In the example of rounding 6,386, why do we round up the hundreds digit?

• Because the digit to the right is less than 5.

• Because the hundreds digit is 3.

• Because the digit to the right is greater than 5.

• Because the digit to the right is equal to 5.

What happens when you round 296,532 to the nearest ten thousand?

• It becomes 290,000.

• It becomes 300,000.

• It becomes 297,000.

• It becomes 296,000.

In the example of rounding 296,532, what do you do when the ten thousands digit is 9 and you need to round up?

• Leave the digit as 9 and change the rest to zeros.

• Change the digit to 0 and carry 1 to the left.

• Leave the digit as it is and change the rest to zeros.

• Change the digit to 10 and adjust the rest.
