When using front-end estimation, we add or subtract the front digits, and then adjust for a more accurate estimation by estimating the sum of the digits to the right of the decimal point.
The difference between a measurement and an estimation is that a measurement is an exact data while an estimation is a guess as to what something may measure. For example, you can use a ruler to get the exact measurements of a piece of paper. However, if you don't have a ruler, you can make an educated guess as to what the paper's length and width measurements may be.

Estimation
It is very easy to find high quality rounding and estimation worksheets for kids on the website WWW.estimation.com , this website also features a "grade" (or "class") filter , which allows more precise results. Also WWW.mathworksheets4kids.com has a wide range of estimation sheets available.
Use estimation when an approximate answer is acceptable.
Estimation is a quick of working out roughly what the answer is
front end estimation means to use only the whole number part of the decimal. we only use whole numbers to do front end estimation
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
When using front-end estimation, we add or subtract the front digits, and then adjust for a more accurate estimation by estimating the sum of the digits to the right of the decimal point.
An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.

Use rounding and estimation to predict the approximate quotient of 285 ÷ 11.
You need to set up an objective function via Maximum Likelihood Estimation, and then use Excel's Solver to maximize it for estimation parameters. Check out the attached link for an example Excel spreadsheet
precision
by comparing the colours or the amount of precipitate
You can estimate when an exact answer is not needed.
