Rounding whole numbers involves replacing a number with the closest number in tens, hundreds, or thousands. To round to the nearest ten, underline the digit in the tens place and if it is 5 or greater, round up the tens place digit. Then change all following digits to zero. The same process is followed to round to the nearest hundred or thousand, examining the hundreds or thousands place digit respectively. Examples show rounding 534 to 530 when rounding to tens, 500 when rounding to hundreds, and 1000 when rounding to thousands.

2. Rounding off in Tens
 Rounding off in Tens is to replace a
number with a number that tells how
close it is to the nearest ten.
 Example:
 27 is closer to 30, so we would round it to
30!
20 21 22 23 24 25 26 27 28 29 30

3. 2 3 7 5
We are rounding to the Tens place,
so we are going to circle the number
in the Tens place.
Move to the right,
Underline next number
2 , 3 7 5

4. If underlined number is 0 to 4,
Circle stays the same
2 , 3 7 5
If it is 5 to 9,
Add 1 in circled number. 7+1 = 8
Digits to the right change to ZERO
2 , 3 8 0

5. 2 3 7 5
We are rounding to the Hundred place,
so we are going to circle the number in
the Hundred place.
Move to the right,
Underline next number
2 , 3 7 5

6. If underlined number is 0 to 4,
Circle stays the same
2 , 3 7 5
If it is 5 to 9,
Add 1 in circled number. 3+1 = 4
Digits to the right change to ZERO
2 , 4 0 0

7. 2 3 7 5
Rounding to the Thousands place,
so we are going to circle the number in
the Thousand place.
Move to the right,
Underline next number
2 , 3 7 5

8. If underlined number is 0 to 4,
Circle stays the same
2 , 3 7 5
Digits to the right change to ZERO
2 , 4 0 0
