Rounding

Rounding

Yesterday I was rounding to the nearest 1000 it was really fun. I had to think about what my answer would be. Here’s an example, if I round to the nearest 1000 and my number is 3431 the answer would be 3000. That was how I done rounding.

rounding to the nearest 1000, 9728 the answer is 10,000

rounding to the nearest 1000, 6790 the answer is 7000

Rounding by a hundred

In maths we did rounding numbers, I did rounding to a hundred (it was challenge 2).

Example .234 to the nearest 100=200

We used different methods to help us like rounding mountain or number line.

About rounding

When you are doing rounding you look at the number you are rounding. It is very important that you know  your place value. If the number one place value behind bigger than five round it up. For example 79 is rounded to 80 .  Rounding is a life skill we need to know how to do for a few jobs. Like in a school you are buying pencils you will round the children to the nearest hundred so you can estemate how many. And for work when you need to copy some sheets you round to see how many you need approximately. Rounding and estimating sometimes go togeth like in the examples I gave you.

 

How I round

I like to round by using my resources like a number line.I also like to round with a hill,what do is I put the two numbers at the top then I see wich one rolls down and one rolls up

Maths rounding

we have been rounding on monday ,tuesday and wednesday and this is an example

317 to the nearsest 10 = 320  

this is rounding to the nearest 100 6946 =6900  

to the nearest 1000 1830 =2000

Maths rounding

Yesterday in maths we were rounding to the nearest 100. For example the number 562 and it rounds up because the tens number is greater then five so you round to 600. Examples of my work 2345 to the nearest 1000=2000.

 

 

rounding numbers

I used the rounding mounting to help me get the anwsers correct and the number line. And I rouded hundreds like this 350 rounded by a 100=400 and Iused a number line and 460roudid by 100=500. It was quite easy .

Rounding

On Monday the 2nd of October, we were learning in maths, rounding. 
If your number is 15 and you rounding to the nearest 10, it would be 20 
because if it was 14 and you were rounding to the nearest ten it would be 10. 

15,243 rounded to the nearest 1,000 is 15,000. 
693 rouded to the nearest 10 is 700. 
3,823 roundeed by the neares-t 1,000 is 4,000

Rounding numbers

In maths we did rounding numbers by using a number line or the mountain to help us . We had lots of challenges to do. Some of the challenges were easy ,hard ,or normal. This is question – 234 rounded to the nearest 10 is 230. Challenge number 1 was quite easy but challenge number 2 and 3 was quite tricky. Rounding was fun!

How to round decimal places

                                    How to round

                                                    Decimal

                                                           Places

 

Step 1.  Choose a number

First, choose a number for example 543.750

Step 2. Round to the nearest whole number 

To round to the nearest whole number, you will need the tenths if you look at the number 543.750 the tenth is the 7. If the  digit you are looking at is 5 and above it goes ↑ if it’s 4 and under, it goes ↓ so the 3 becomes a 4 so you have 544

Step 3. Round to the nearest tenth

          Now to round to the nearest tenth you look at the number behind the tenth so you will be looking at 5, it’s above 5 so the 7 turns into an 8. Now that your number is 543.8

Step 4. Round to the nearest hundred

To round to the nearest hundred its similar to tenths, you look at the number behind it, in this case 0 so it doesn’t go up at all so your number is 543.75.
