In class, we have been working on rounding numbers!
Here are the rules for rounding:
Here are the rules for rounding:
Radical Rounding Rules!
1. Underline the place value position to which you are rounding.
2. Write which two tens or two hundreds the number is between.
3. Draw an arrow to the neighbor on the right.
4. Think: ♬ ♫ "If the neighbor next door is 5 or more, round up, round up!" ♫ ♬
(If the neighbor is a 5, 6, 7, 8, or 9 round up. If the neighbor is a 4, 3, 2, 1, or 0 round down.)
5. If it's not 5 or more, round down!
6. Circle the correct estimate/answer.
Here is a video tutorial we made last year to demonstrate the rules for rounding!

I did pretty well on the rounding quiz. My score was probably 95% because most of the problems were rounding tens, hundreds, and thousands.
ReplyDeleteFor example, you round 85 to the closest ten or 90, 371 to the closest hundred or 400, and 3,297 to the closest thousand or 3,000. 85 is between two tens, 80 and 90. The ones in 85 is five, so you round up to 90. 371 is between 300 and 400. The neighbor is 71, which is higher than 50, so you round up to 400.
Dear Mrs. Yollis,
ReplyDeleteMan! I remember that video! I don't remember my score, but I probably did well. Currently I am in fifth grade and we did rounding two weeks ago. Yesterday and Today, we are learning expressions.
Here is a tough one: What is the nearest hundred in 4,351,120?
If you look on the comment above me, you will see that this person gave examples. It really helped me because, one, I went to this as a learning tool, two, once I had figured out how to do it, I went back to this as a reference.
See if you can beat my question and give me a hard one!
Sincerely,
