Remember the steps for rounding numbers.
1. Underline the digit in the place you are rounding to.
2. Circle the digit to the right of the underlined numbers.
3. If the circled number is less than 5, leave the underlined number alone.
4. If the circled number is 5 or more, raise the underlined number one.
5. All digits to the right of the underlined number change to zeros.
6. All the digits to the left of the underlined number stay the same.
