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.

What is the difference between rounding to a specified place value and estimating using front-end rounding?
Front end estimation is simpler but usually more crude.
What is different about rounding and estimating?
You use rounding TO estimate. For instance, estimating is 2.8 + 3.9 is about 7. Rounding is 2.8 is about 3 and 3.9 is about 4. When you estimate, you're rounding MULTIPLE numbers which you will then add, multiply, etc. to get an ESTIMATE! when you're rounding, you need to be given a certain number and you make it less specific. for example, the population of whoville is 693044. if I'm rounding to the nearest thousand, then the answer is 693000. numbers 5 and up are rounded up. numbers 4 and below are rounded down. when you're estimating, you're basically making an educated guess without knowing the real number. for example, you're looking at a bag of jellybeans and you guess there's 750 in there. it seems like a reasonable number so you estimate that.
