Mrs. Ranney's new class has been exploring number sense!
Standard form: A way of writing numbers using digits
Expanded form: A way to write numbers by showing the VALUE of each digit
Word form: A way to write numbers using words
To practice with forms of a number, we found that we could use
the Clustr Map on our Blog!
We have had 25,968 visitors to the blog since October 2009.
We showed that number in all three forms!
We have reviewed skills with the hundred chart and odd and even digits by playing some games!
Other students played manual Dog Bone!
The symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are digits.
The even digits are 0, 2, 4, 6, and 8.
The odd digits are 1, 3, 5, 7, and 9. Standard form: A way of writing numbers using digits

Many students played Odd and Even with a partner.

Dear Mrs. Ranney's class,
ReplyDeleteWelcome to your new school year. Looking at numbers is a very interesting start.
Through history, numbers have not always looked the same as the digits we use now. We all know our digits...
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Using these ten digits, we can write any number no matter how large but this wasn't always so. In ancient Roman times, writing numbers was very different. The Romans used...
I, V, X, L, C, D, M
These were used for...
I=1, V=5, X=10, L=50, C=100, D=500, M=1000
Writing what we counted was very different. Counting to ten looked like this...
I, II, III, IV, V, VI, VII, VIII, IX, X
I think it's much easier using our digits. The Ancient Romans didn't, as far as I know, have numbers for 5000, 10,000 or numbers up to a million. After all, why would you need to count so high?
The Ancient Egyptians also had their own numbers. You can see them here…

Have fun with numbers, everyone. I always enjoy discovering new number facts and ideas. :)

Dear Mr. Mannell,
DeleteThank you so much for visiting our blog. We hope to hear from you often!
Thank you for showing us all those wonderful numbers that the Romans used. We might start using them in class!
We know two more interesting facts about numbers: The Greeks invented infinity, and the Mayans invented the zero!
Some of us think that our traditional numbers are easier!
Thanks again, especially for helping us raise our blog visitor count!
Best wishes from your new friends,
Mrs. Ranney's Third Graders!

Dear Mrs. Ranney,
ReplyDeleteI have played Dog Bone. My highest number of bones I could place in one minute was 7. The numbers that were easy to place was 1,10,91 and 100 because they all go in the corners.An example of my strategy is if the number was 71 I would go to the 80 and then go backwards.
Sincerely,
Matthew
Dear Matthew,
DeleteI'm glad you were able to play Dog Bone! Thanks for sharing such wonderful strategies!
Keep on blogging!

Mrs. Ranney
Dear Mrs. Ranney and Class,
ReplyDeleteThis sure looks like a fun way to start off the school year. I'm excited that you are teaching the kids some html!

Dear Mrs. Ranney,
ReplyDeleteI played digital dog bone at school. I got all 10 bones. The number 1 is easy because it is the first number and the number 100 is easy because it is the last number. If the number was 76 you would find the 7 on the side and the 6 on the top, and find where they connect.

Dear Rain,
DeleteI'm glad that you enjoyed playing Dog Bone at school. Thanks for sharing your strategies!
I am very impressed with how you are using html code!
Keep up the great work!
Cheers,
Mrs. Ranney
Dear Mrs. Ranney,
ReplyDeleteA.J. and I played the Dog Bone game, and it was fun. We only got 7 bones.
Sincerely, A.J. and Ruthie
Dear A. J. and Ruthie,
DeleteI'm so glad that you both were able to play Dog Bone. I know if you keep playing your scores will improve!
Do you have any strategies to share for placing numbers?
All the best,
Mrs. Ranney
Dear Mrs. Ranney
ReplyDeleteI played digital dog bone and got 10 bones. The easiest numbers are 1,2,3,4,5,6,7,8,9, and 10 beacause they are in the first row.

Dear Jackson,
DeleteI'm glad to hear that you've played Dog Bone! I agree about the first row being easiest to place!
Do you have any strategies to share about placing other numbers?
Sincerely,
Mrs. Ranney
Dear Mrs. Ranney,
ReplyDeleteI played Dog Bone 4 times. My scores were 7, 8, 8, and 10! It was so much fun.

Dear Alex,
DeleteI'm glad you've enjoyed playing Dog Bone! You have achieved some great scores! Do you have any strategies to share?

Dear Mrs.Ranney,
ReplyDeleteI've been having a great time in 4th grade. I'm learning a lot of new things. I've been learning new grammar. This year I got a teacher named Mrs.Krauss. She is really nice. I also have been using some of the strategies you taught me.
Your Old Student,
Francesca:)
Dear Francesca,
DeleteI am so glad to hear from you! It's wonderful to hear that you are learning new things from Mrs. Krauss. She is a terrific teacher, and I'm sure she's happy to have you in her class.
I am even happier to hear that you are using some of the strategies that you learned in my class! I hope you and all your classmates have a super 4th grade year!
Cheers,
Mrs. Ranney
Dear Mrs.Ranney,
ReplyDeleteGuess what? I played Digital Dog Bone and got 10 bones! It was so much fun!
The easiest numbers are 100, 1, and 10 for me because 10 is the last number in the first column. The numbers 1 and 100 are easy because 100 is the last number on a hundred chart and 1 is the first number.
I love Digital Dog Bone!
Cheers,
Jules
