1)Rounding is to make a number closest to the nearest tens, hundreds,thousands or ten thousands.For example, 43 will be rounded off to 40 and 45 will be rounded off to 50.

2)Estimation is a rough calculation of a value.For example,sometimes in a event to win some prizes you might have to guess the number of balls in a container and you have to try and estimate the number of balls.

3)I think we are learning rounding and estimating to apply in real life situation like the example in number 2 and also when in estimating the discounted price of an item.

Qn 1 Rounding is the process of replacing a no. by another no. of approximately the same value.Anything after 5 at the ones place , the tens place will be added by 1. Anything before5  at the ones place , the tens will not be changed.                                                                                                                      Qn  2 Estimation is a close guess of the actual value . It can be used to check whether a calculation is reasonable                         Qn 3      I think we are learning rounding and estimating is  making the sum easier to solve.

Question 1 : Rounding is to make a number into the nearest whole number.

Question 2 : Estimation is to guess a number or quantity of something.

Question 3 : We are learning rounding and estimating because in future we will be using it a lot in our work and daily lives.

# data[].attributes.body
Question 1

Rounding means changing a number but keeping its value close to what it was. The result will be less accurate, but easier to use.

We round up when the number in the ones place is 5 or greater and round down when the number in the ones place is 4 or lesser.

Example: 33 rounded to the nearest ten is 30. 38 rounded to the nearest 10 is 40

Question 2:

To estimate means to find something close to the correct answer. In other words, you are approximating.The exact number of candies in this jar (see picture below) cannot be determined by looking at it, because most of the candies are not visible. In such cases, we need to use estimation when the number to count is too high to be counted at that moment.

Question 3:
We learn rounding so we can make large numbers easier to work with.
We use estimation in situations where we don’t know the exact answer but can make
a best guess. For example, I use estimation to gauge the length of time I need to complete my homework.

# data[].attributes.body
Question 1: Rounding is changing numbers into the nearest tens, nearest hundreds or nearest thousands.
For example, round 3582 to the nearest tens. The answer is 3580.
Question 2:
Estimation is guessing the value, cost length or weight of something.
For example, estimate the length of a door. my estimation will be 3 metres.
Question 3:
I think we are learning rounding and estimation to make counting numbers or things easily,such as paying money. They would also help count, multiply and divide numbers quickly and accurately.

Question1:Rounding

# data[].attributes.body
1)rounding off is like making a number go to its nearest tens,hundreds,thousand.....It's like you want to round 1128 to nearest tens it will become 1130 so what I have to do is to look at number 2(which is in the tens place)and look at the number on its right if it is 5 and above means I can increase the number 2 to three but no matter what the number 8 will become 0
2)estimation is like to guess a number near the correct number
3)We may need to use rounding and estimation in future

Q2 I THINK ESTIMATION MEANS TO GUESS A  NUMBER OR VALUE
Q3 I THINK WE ARE LEARNING ROUNDING AND ESTIMATION BECAUSE SOMETIMES WE NEED IT OUR DAILY LIVIES

# data[].attributes.body
Q1) I think rounding means to rounding up or down the number to the nearest five or ten to divide, multiply, add or subtract to find out what is the answer if you don't really need to know what is the specific answer. Example:(if rounded to the nearest ten) 26 is closer to 30 but not  as close to 20. (if rounded to the nearest five) 26 is closer to 25 but not as close to 15 or 35.

Q2) Estimation is a rough guess of what is the answer.

Q3) We are learning rounding and estimation because it will help us everyday for example if there is a discount of 20% for some books then you have to do rounding, estimation or both to find out whether or not it is worth buying those books.

Q1: I think rounding is transforming a number to the nearest ten , hundred or thousand . if the number is exactly between, example the number 5, it will be rounded of to ten ,not 1.
Q2 : I think estimating is nearly the same as rounding . turning it to the closest number you can .
Q3 I think that we are learning this is because it might appear in our end of year exam : ) thank you for reading ( if you read it )

# data[].attributes.body
I think rounding means to change a number to an easier form but keeping it close to the value . Eg: We round 12 to 10 because it is an easier form and it is close to the value.

Q2. Estimation means to find something close to the answer by not calculating it.

Q3. I think we are learning these because it will appear in our exams.

Q1: Rounding is to move a number to its nearest ten, hundred , thousand, ten thousand... Example: If the number the question gave you is 26, to round it, you must move it to the nearest ten, which is 30.The answer is not 20 because you need 6 to get 26, whereas for 30, you only need 4.                                                                                            Q2: Estimation is to guess a number that is   close to the actual answer but not the exact answer. Estimations could be accurate or inaccurate. It depends if yours is a lucky guess or not, but if your estimation is inaccurate, it's okay. Most of the time, people's estimations are inaccurate. How to estimate - Example: If there are a lot of cookies in a jar, you could estimate the number of cookies in the jar first, before really counting the actual number of cookies in that jar.
Q3: I think rounding and estimation will help everyone in their work, including me. As our level goes higher, the number gets greater and greater, so we can use rounding and estimation in our work, including this year. Once I learn rounding and estimation on Monday, I'll never forget how to round and estimate as I grow older.

Q2 Estimation is a rough calculation Example if you fill a container with water and want to find the volume of water you might want to estimate before finding the real volume of water

Q3i think

# data[].attributes.body
Hi, here's what I know about rounding and estimation:
Q1 : Rounding is shifting a number to the nearest ten, hundreds or thousands. If your  numbers in the ones place are five or above, round it UP to the nearest ten ( for example you round  38 to 40 ). If the number in  the ones place is below five, round it DOWN ( for example 94 you round to 90 ) Rounding makes doing math more easy but is less accurate.
Example:
49 + 73 =
You round 49 to 50, then 73 to 70. Then the answer will be 120

Q2: Estimation is a rough calculation of a number,  value or quantity.
Something like  guessing, but you still don't completely rely on guessing. You will still have some thing to refer to and calculate on.  More like predicting. And you should not use any working for estimation. Just mental calculation. But you usually don't do calculation. It's looking and then your mind process around how much ( or how many ) is there. And you also estimate volume, weight, length and area.... You estimate all kinds of things. Last time I went to a Lantern Festival party, they ask you to GUESS how many moon cakes are there. I counted how many rows and how much on each row, but the moon cakes on each row is not the same. So I tried to times but... it did not work. THAT is estimation.
Example:
Estimate how long is the classroom.
You do guess alright, but you know the classroom is longer then 1 m, so it cannot be cm. And you think that the classroom is longer than 2 m, so then you guess how long is the classroom but the answer needs to be after 2 m.

Q3:  I think that we are learning rounding and estimating because it makes it quicker and easier to do math questions even though they are less accurate. But they are handy for roughly calculating numbers (like calculating how many people came to a theme park today). Plus, they might help us in our daily work and in the future.
Thanks! :)

Qn 1: Rounding is shifting a number (for example 76) to the nearest ten (80). (Actually you must use a symbol for rounding off, but I can't find it on the keyboard )
Qn 2: Estimation is figuring out a sum with no working, so it also uses the rounding concept. You may be given a sum like 77+22. You have to first round off both numbers ( They will be 80 and 20), then, add up the rounded off numbers (80+20). The answer will be 100.
Qn 3: I think we are learning these topics as it can make sums easier.
