Skill: Round numbers to a specified place value

To round a whole number:

1. Find the place value you are rounding to.
2. Look at the digit immediately to its right.
3. If that digit is $5$ or greater, increase the target digit by $1$.
4. If that digit is less than $5$, leave the target digit unchanged.
5. Change all digits to the right of the target place to zeros.

Example: Round $48{,}763$ to the nearest thousand.

• The thousands digit is $8$:

$$48\boxed{8}763$$

• The digit immediately to its right is the hundreds digit, $7$.
• Since $7$ is greater than or equal to $5$, round the $8$ up to $9$.
• Change the hundreds, tens, and ones digits to zeros.

Therefore,

$$48{,}763 \approx 49{,}000$$

So, $48{,}763$ rounded to the nearest thousand is $49{,}000$.
