Rounding numbers worksheet for Grade 6 students, focusing on rounding numbers up to millions.

Problem Description:

The task is to round each given number to the digit underlined. The numbers are provided in a worksheet, and we need to solve each problem by rounding the numbers correctly.

Solution Approach:

1. Identify the Underlined Digit: Each number has an underlined digit, which indicates the place value to which the number should be rounded.
2. Determine the Rounding Rule:
- If the digit immediately to the right of the underlined digit is 5 or greater, round up the underlined digit by 1.
- If the digit immediately to the right of the underlined digit is less than 5, keep the underlined digit as it is.
3. Replace All Digits to the Right of the Underlined Digit with Zeros (if necessary).

Step-by-Step Solutions:

#### 1. 9,059
- Underlined digit: 9 (ones place)
- Digit to the right: 0
- Since 0 < 5, do not round up.
- Result: 9,059
