We do it&nbsp;all the time. Look at the image given below. We can see that Eddie, in the image below, is not exactly 2 feet tall but he is close to it. So, we can estimate his height and say that he is about 2 feet tall.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"354\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/estimate-1.png\" alt=\"Eddie standing next to a height chart, approximately 2 ft tall\" class=\"wp-image-23470\" title=\"Eddie standing next to a height chart, approximately 2 ft tall\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/estimate-1.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/estimate-1-300x171.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">A few more such examples:<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Estimating time: Sara walks to school from home in about 10 minutes.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Estimating quantity: About a 1000 people will attend the concert.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Estimating distance: The distance between New York to San Francisco is approximately 2900 miles.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">So, the question is, what is an estimate?&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">An <strong>estimate<\/strong> is an approximate calculation or rounding of the number to the nearest place value for the sake of convenience. There\u2019s no single way to define estimation. The closest meaning of an estimation is a guess or an assumption about a value that isn\u2019t too far off. What is an estimate in Math? Definition for estimate in math is an approximate value close enough to the correct value. A lot of guesses are made to make math easier and clearer.&nbsp;<\/p>\n\n\n\n<div id=\"recommended-games-container-id\" class=\"recommended-games-container\"><h4

class=\"eplus-wrapper wp-block-heading\" id=\"1-definition-of-estimation\">Definition of Estimation<\/h2>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Estimation<\/strong> is a rough calculation of the actual value, number, or quantity for making calculations easier.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Example: When taking a cab or waiting for a bill at a restaurant, we tend to <strong>estimate<\/strong> the amount to be paid.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">In short, it is an approximate answer. And this figure is often used to check the accuracy or correctness of the final answer. Estimation helps when a certain margin of error is allowed in a calculation. It gives an answer without using a calculator or written calculations. The whole point of the exercise is for you to devise a plausible approximation.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Most of the time, estimation in math is done by rounding off the numbers to their closest whole value to get a quick and simple rough answer. It saves time and effort.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">For instance,<strong> <\/strong>kids use estimation many times a day without realizing it. They tend to figure out how long they play and how long they have for recess.&nbsp;<\/p>\n\n\n\n<div id=\"recommended-worksheets-container-id\" class=\"recommended-games-container\"><h4

The <strong>estimated<\/strong> answer is easier to use. Rounding off comes in handy while finding solutions to <strong>estimation questions.<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Let us consider an <strong>example of estimation<\/strong>: The headmistress of a school <strong>estimates<\/strong> that about 24 students are standing in rows in the playground. She does this by counting the number of students in a single row and then multiplying that figure by the total number of rows.

Next, we check the number to its right. Example: To round off to the nearest ten, we check the ones place.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">1) If the number is less than 5, we round it down.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">For example, 723 rounded off to the nearest ten is 720.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We drop 3 since $3 \\lt 5$. We do not change the tens digit.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">2) If the number is more than or equal to 5, we round it up.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">For example, 787 rounded off to the nearest ten is 780.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We round the tens digit 8 up to 9 since $7 \\gt 5$.<\/p>\n\n\n\n<h2 class=\"eplus-wrapper wp-block-heading\" id=\"7-how-to-estimate-different-place-values\">How to Estimate Different Place Values?<\/h2>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The simplest way to estimate is by rounding off numbers to the nearest whole number.&nbsp; Rounding off helps achieve an approximate answer faster. For example, Laura pays a monthly installment of $\\$3950$ for her new house. We can round off this number to $\\$4000$ to simplify.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">You can round off a number to the nearest 10, 100, or 1000 and so on.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">When working on problems involving large numbers, we may have to <strong>estimate<\/strong> our answers to the closest million or billion. Let us understand this better with the <strong>estimated digit examples.&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Example: Let\u2019s round off the number 381.93 to three different place values.<\/p>\n\n\n\n<ol class=\"eplus-wrapper wp-block-list\">\n<li class=\" eplus-wrapper\">Round it to a whole number:<\/li>\n<\/ol>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">It means we wish to lose the decimal part. The tenth place is 9, which is greater than 5. So, we round it up. Let us increase the digit in one&#8217;s place by 1. We will get 382.<\/p>\n\n\n\n<ol start=\"2\" class=\"eplus-wrapper wp-block-list\">\n<li class=\" eplus-wrapper\">Round to the nearest ten:&nbsp;<\/li>\n<\/ol>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">To round a number to the nearest ten, we check the ones place. Here, it is 1. We round it down, since $1 \\lt 5$. We will simply drop 1. The rounded number is 380.<\/p>\n\n\n\n<ol start=\"3\" class=\"eplus-wrapper wp-block-list\">\n<li class=\" eplus-wrapper\">Round it to the nearest hundred:&nbsp;<\/li>\n<\/ol>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The tens place is 8. We round it up and increase the digit in the hundreds place by 1. The rounded number is 400.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">4. Round it to the nearest tenth:<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The hundredths place is 3 and $3 \\lt 5$. So, we drop 3 and round the decimal to 381.9.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>General Rule of Estimation Summary:<\/strong><\/p>\n\n\n\n<ul class=\"eplus-wrapper wp-block-list\">\n<li class=\" eplus-wrapper\">As soon as you pick the number you want to estimate\/round, first find the digit at the place you want to round the number to.<\/li>\n\n\n\n<li class=\" eplus-wrapper\">Next look at the digit right to that place to see which way you will round.&nbsp;<\/li>\n\n\n\n<li class=\" eplus-wrapper\">If the digit to the right is four or less (as in 4, 3, 2, 1, 0), your number remains the same.&nbsp;<\/li>\n\n\n\n<li class=\" eplus-wrapper\">If the digit to the right is five or higher (as in 5, 6, 7, 8, or nine), your number increases by one.&nbsp;<\/li>\n\n\n\n<li class=\" eplus-wrapper\">In the end, all the extra digits that weren\u2019t rounded off, should be removed.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">A quick way to remember this rule is:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"449\" height=\"351\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/estimate-4.png\" alt=\"Fun way to remember estimation rules\" class=\"wp-image-23474\" title=\"Fun way to remember estimation rules\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/estimate-4.png 449w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/estimate-4-300x235.png 300w\" sizes=\"auto, (max-width: 449px) 100vw, 449px\" \/><\/figure>\n\n\n\n<h2 class=\"eplus-wrapper wp-block-heading\" id=\"8-estimation-in-real-life\">Estimation in Real Life<\/h2>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Estimating<\/strong> is a vital part of our daily lives. We are always <strong>estimating<\/strong> things, sometimes without even being aware of it.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Example 1:<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">When we are purchasing a few things at the supermarket, we try to <strong>estimate<\/strong> the total cost in our head.&nbsp;The <strong>estimated<\/strong> amount is usually a round number in tens, hundreds, or even thousands, depending on what items we wish to purchase.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">Suppose you buy three items whose prices are $\\$2.35$,&nbsp; $\\$13.85$ and $\\$4.25$.

It is a concept that helps you gauge, analyze and come up with solutions. It encourages you to think out of the box.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">It also improves your attention to detail and makes you a better negotiator. Now that you have all the skills required to be an expert at <strong>estimating<\/strong>, I <strong>estimate<\/strong> that you are about to have a good time with it.<\/p>\n\n\n\n<h2 class=\"eplus-wrapper wp-block-heading\" id=\"12-solved-examples\">Solved Examples<\/h2>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>1.

Round off his percentage to the nearest whole number.&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Solution<\/strong>: Aaron scored approximately 88% in seventh grade Science finals. This estimation was made after rounding off the number 87.91% to the nearest whole number. Since the number to the right after the decimal is 9 which is greater than 5, the number to the left(7) increases by one digit.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>7. Gina collected 56 coins and Carol collected 86 coins. Choose a better estimate to find the number of coins they own together.&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>Solution<\/strong>: Gina collected 56 coins. We can round off 56 to 60 coins and we can round off 86 to 90 coins. After adding 60 and 90, we get 150. The estimated answer is 150.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\"><strong>8. Sam wants to buy 5 books, each costs <\/strong>$\\$2.95$<strong>.
