Fill in the missing numbers from 1 to 100 on this fun and educational worksheet.

Problem Description:

The task is to fill in the missing numbers between 1 and 100 in a grid. The grid has 10 rows and 10 columns, and the first number (1) and the last number (100) are already provided.

Solution Approach:

1. Understand the Grid Structure:
- The grid has 10 rows and 10 columns.
- Each cell in the grid represents a number from 1 to 100.
- The numbers should be filled sequentially from left to right and top to bottom.

2. Identify the Pattern:
- The first row starts with 1 and ends with 10.
- The second row starts with 11 and ends with 20.
- This pattern continues until the last row, which starts with 91 and ends with 100.

3. Fill in the Numbers:
- Start with the number 1 in the first cell.
- Increment the number by 1 for each subsequent cell moving from left to right.
- After filling a row, move to the next row and continue the sequence.
