My math book has this statement:
"Describe how to use a Ten-Thousand Square to round numbers to the nearest 1000?"
I don't really understand how to answer it.
Is this the answer?:
If the number in the thousands place is greater than 5, you round up. If the number is less than 5, you round down.
10,000 squared (10,000^2) is 10,000 times 10,000. Since the answer has only zeros, no rounding is needed.
Round up if the value is 5 or greater.
I hope this helps. Thanks for asking.
To use a Ten-Thousand Square to round numbers to the nearest 1000, you can follow these steps:
1. Identify the digit in the thousands place of the number you want to round. This is the fourth digit from the right.
2. Look at the digit immediately to the right of the thousands place digit. If this digit is 5 or greater, the number in the thousands place will be rounded up to the next higher thousand. If it is less than 5, the number will be rounded down to the nearest thousand.
3. If you need to round up, add 1 to the digit in the thousands place.
4. Replace all the digits to the right of the thousands place with zeros. This effectively rounds the number down or up to the nearest thousand.
To better understand how to use a Ten-Thousand Square, let's consider an example:
Example: Round the number 3,986 to the nearest 1000 using a Ten-Thousand Square.
1. The thousands place digit in 3,986 is 9.
2. The digit immediately to the right of 9 is 8, which is less than 5.
3. Since 8 is less than 5, we do not need to round up.
4. Replace the digits to the right of the thousands place with zeros: 3,000.
Therefore, 3,986 rounded to the nearest 1000 is 3,000.
Remember, a Ten-Thousand Square is a helpful tool to visualize the process of rounding numbers to the nearest 1000.
