Rounding, you see the number and just make it look neater or easier to use. Estimating, you guess a number.

Is rounding the same thing as estimating?

No,Rounding means reducing the digits in a number while trying to keep it's value similar. The result is less accurate, but easier to use.This is the common method* Decide which is the last digit to keep* Increase it by 1 if the next digit is 5 or more (this is called rounding up)* Leave it the same if the next digit is less than 5 (this is called rounding down)Example: 243 rounded to the nearest ten is 240 (because 3 is less than 5)And estimating is a close guess of the actual value, usually with some thought or calculation involved.Example: Alex estimated there were 10,000 sunflowers in the field by counting rows.Hope the definitions and examples helped you understand that estimating and rounding are not the same thing.

When estimating three digit numbers how do you round to the nearest tenth?

To round any number, look at the digit to the right of the place you are rounding to. If the digit is 5 or more, change the digit in the place you are rounding to to the next higher digit. If the digit to the right of the place you are rounding to is less than 5, leave the digit in the place you are rounding to as it is. Change all digits to the right of the place you rounded to to zeros.
