In this article, we will offer you Grade 3 free printable estimating and rounding worksheets to help your 3rd graders practice and learn how to estimate and round numbers like a pro.

Estimating and rounding are two essential skills that 3rd graders need to learn and master. They help you work with large numbers quickly and easily without having to do complicated calculations. They also help you check your answers and make sense of realworld problems.
It is important to learn these two vital math skills in a fun and engaging way to enhance kids’ mastery and eagerness to solve. That is no problem. Mathskills4kids.com will provide your children with amazing strategies for quickly mastering and solving estimation and rounding problems.
But what exactly are estimating and rounding, and how do you do them? Let's find out!
Why estimating and rounding are important skills for 3rd Graders
Estimating means making a reasonable guess about how much or how many something is. For example, if you see a jar of candy, you can estimate how many pieces are inside by looking at the size and shape of the jar and the candy. Estimating helps you get an idea of the quantity or value of something without having to count or measure it exactly.
Rounding means making a number simpler or easier to work with by changing it to the nearest multiple of 10, 100, or 1000. For example, if you have 487 pencils, you can round it to 500 pencils by changing the last two digits to zero. Rounding helps you simplify large numbers and make them easier to add, subtract, multiply, or divide.
Estimating and rounding are important skills for 3rd graders because they help you:
 Develop number sense and place value understanding
 Compare and order numbers
 Solve word problems involving addition, subtraction, multiplication, or division
 Make reasonable predictions and judgments
 Communicate your thinking clearly and effectively

How to estimate numbers using different strategies
Different ways and strategies exist to estimate numbers depending on the situation and purpose. Here are some common strategies that you can use:
 Frontend estimation: This means using the first digit of each number to estimate the sum or difference. For example, if you want to estimate 234 + 567, you can use frontend estimation by adding the first digits of each number: 200 + 500 = 700. This gives you an approximate answer that is close to the actual answer of 801.
 Compatible numbers: This means using numbers that are easy to add, subtract, multiply, or divide mentally. For example, if you want to estimate 48 x 25, you can use compatible numbers by rounding 48 to 50 and 25 to 20: 50 x 20 = 1000. This gives you an approximate answer that is close to the actual answer of 1200.
 Benchmark numbers: This means using numbers that are familiar or easy to work with as reference points. For example, if you want to estimate how many cups of water are in a gallon, you can use benchmark numbers by knowing there are 4 cups in a quart and 4 quarts in a gallon: 4 x 4 = 16 cups. This gives you an exact answer that is easy to remember.

How to round numbers to the nearest ten, hundred, or thousand
Rounding numbers is another way to estimate numbers by making them simpler or easier to work with. Here are the steps to round numbers to the nearest ten, hundred, or thousand:
 Identify the place value that you want to round to. For example, if you want to round to the nearest ten, look at the tens place.
 Look at the digit to the right of the place value you want to round to. For example, if you want to round to the nearest ten, look at the ones place.
 If the digit is 5 or more, increase the digit in the place value you want to round to by one. For example, if you want to round 37 to the nearest ten, look at the ones place, which is 7. Since it is more than 5, increase the digit in the tens place, i.e., 3 by one: 3 + 1 = 4.
 If the digit is less than 5, keep it in the place value you want to round to as it is. For example, if you want to round 32 to the nearest ten, look at the ones place, which is 2. Since it is less than 5, keep the digit in the tens place, 3 as it is: 3.
 Change all the digits to the right of the place value you want to round to zero. For example, if you want to round 37 to the nearest ten, change the ones place to zero: 40. If you want to round 32 to the nearest ten, change the ones place to zero: 30.

Fun and engaging activities to practice estimating and rounding
Now that you know how to estimate and round numbers, it's time to practice and have fun with them! Here are some fun and engaging activities that you can do at home or at school to practice estimating and rounding:
 Estimation jar: Fill a jar with small objects like candy, marbles, or beans. Ask your friends or family members to estimate how many objects are in the jar by looking at them. Please write down your estimates and compare them with the actual count. See who has the closest estimate and reward them with some of the objects from the jar!
 Rounding bingo: Make a bingo card with different numbers on it. Have someone call out numbers rounded to the nearest ten, hundred, or thousand. Mark the numbers on your card that match the calledout numbers. The first one to get five in a row, column, or diagonal wins!
 Estimation station: Set up different stations around your room or house with items you can estimate. For example, you can have a station with a scale and some fruits that you can estimate their weight, a station with a measuring tape and some furniture that you can estimate their length, width, or height, or a station with a timer and some activities that you can estimate how long they take.
Go around the stations and write down your estimates. Then check your estimates with the actual measurements or times. See how close you are and try to improve your estimation skills!

How estimating and rounding can help 3rd graders in real life
Estimating and rounding are not only useful for math class but also for reallife situations. Here are some examples of how estimating and rounding can help 3rd graders in real life:
 Shopping: You can use estimating and rounding to plan your budget and compare prices. For example, if you want to buy a shirt that costs $12.99 and a pair of jeans that costs $24.99, you can estimate the total cost by rounding each item to the nearest dollar: $13 + $25 = $38. This gives you an idea of how much money you need and how much change you will get.
 Cooking: When you cook or bake, you can use estimating and rounding to measure ingredients and portions. For example, if you want to make cookies that require 2/3 cup of sugar and 1/4 cup of butter, you can estimate the amount of sugar by using a 1/3 cup measure twice: 1/3 + 1/3 = 2/3.
You can also estimate the amount of butter by using a knife to cut a stick of butter into four equal parts: 1/4.
 Traveling: When you travel or go on a trip, you can use estimating and rounding to plan your time and distance. For example, if you want to go to a museum 15 miles away from your house and it takes about 20 minutes to drive one mile, you can estimate how long it will take to get there by rounding the distance to the nearest ten: 20 miles. Then multiply by 20 minutes: 20 x 20 = 400 minutes. Then divide by 60 minutes: 400 / 60 = 6 hours and 40 minutes.
