## This week, Mrs. Ranney's class has been working very hard at learning to round numbers!

## Here are some basic rules to help you remember what to do:

## How to Round Numbers

- Decide which two round numbers the number you are working with is between
- Choose the lower number if the digit next door to the place you are rounding is less than 5
**If the digit next door is 5 or more, round up!**

### Example: Round 74 to the nearest 10

- 74 is between 70 and 80
- The digit next door to the tens place is 4, so
*round down*to 70

**Answer: 70**

(74 gets "rounded down")

### Example: Round 86 to the nearest 10

- 86 is between 80 and 90
- The digit next door to the tens place is 6, so
*round up*to 90

**Answer: 90**

(86 gets "rounded up")

How did you do on the rounding quiz?

How about asking a rounding question in your comment?

Once others write comments, look for question you can answer!

Dear Class,

ReplyDeleteI took the rounding quiz and only missed one problem. Here is a question for you. Please round 4,596 to the nearest thousand.

See you in class tomorrow,

Adam:)

Dear Mrs. Ranney and class,

ReplyDeleteI had fun doing the rounding quiz.I got most of them right. I have a rounding question for you. Please round 34 to the nearest tens.

Warmly,

Maya

Dear Mrs. Ranney,

ReplyDeleteWhat does 39,564 round to? I'd love to know. I'm having

a lot of fun doing rounding with you. I can not wait to learn more. I can not believe how much I am learning.

I hope we will have a lot of fun learning math together.

Your classmate,

Grace

@Maya, I'm glad to hear that you've been reviewing rounding with the quiz! You asked a great question. Let's see who answers you!

ReplyDelete@Grace, I'm glad to hear that you've enjoying learning about rounding! It can be tricky, but I know you're up to the challenge. You asked a question with a large 5 digit number! What place would you like the class to round it to?

Keep up the good work, girls!

All the best,

Mrs. Ranney

Dear Class,

ReplyDeleteWhat two thousands is 4,712 between? For what two hundreds is 7,912 between? What two tens is 3,567 between? For what two hundreds is 374 between? What two tens is 947 between? Please get me an answer quick.

See you tomorrow,

Josh

Dear Grace,

ReplyDeleteI'm not precisely sure what value you want me to round to.Here are some posibilities:

-If you want me to round to the nearest hundreds it would be 34,600,to the nearest thousand it would be 40,000,to the nearest tens it would be 39,560.

See you in 11 hours and 45 minutes,

Quynh Anh

@Quynh Anh, what a clever response to Grace's question! You gave her all the possible answers! Good for you.

ReplyDelete@Josh, you certainly came up with some challenging questions! I hope someone has a chance to answer before they have to go to bed!

Keep up the good work, you two!

Sincerely,

Mrs. Ranney

Dear Class,

ReplyDeleteI loved the rounding and it's a great and fun way to practice. To answer one of Josh's questions, 4,712 is between 4,000 and 5,000. If we were to round it to the nearest thousand it would be 5,000.

See you in a little while,

Eve

Dear Mrs. Ranney and class,

ReplyDeleteI enjoyed doing the math quiz.It was the perfect start to my day.

See you in class!

Sincerely,

Bella

Dear Mrs. Ranney,

ReplyDeleteRounding numbers was really interesting, and it helps me a lot in math.

See you tomorrow.

Your student

Oliver

Dear Mrs. Ranney,

ReplyDeleteHow are you doing? I am doing great, and guess what! Jamie is in my class this year. Justin sits next to me in class. In math class I am #6, and we are rounding to the nearest million. I know a lot of kids in your class this year, and some of them know me too. I also am not talking in class. Mrs. Krauss is my teacher, Mrs. Kaplan is my math teacher, and Mrs. Sank is my science teacher.

Best Wishes,

Raelynn :)

Dear Class,

ReplyDeleteWhat is 4,999 rounded to the nearest thousand and the nearest hundred? I would love to get you thinking about it.

Your classmate,

Eve

Dear Class,

ReplyDeletePlease round 27,743 to the nearest hundred. Can you round the same number to the nearest thousand? Please give me your answers as soon as possible.

Your classmate,

Andrew

Dear Mrs.Ranney and class,

ReplyDeleteI got none of the questions wrong on the rounding quiz. Can one of you answer this question. Please round 27,509 to the nearest thousand ?

Your classmate,

Gregory

Dear Mrs.Ranney and class,

ReplyDeleteI loved the rounding quiz.I got all of the questions right.I have a rounding question for you.Please

round 19,489 to the nearest hundred.

I love doing math together.

your classmate,

Vanessa

Dear Gregory,

ReplyDeleteThe answer to your question is that 27,509 rounded to the nearest thousand is 28,000.

See you in class,

Eve:)
