- The first grid contains the hundreds: 100, 200, 300, 400, 500, 600, 700, 800, 900.
- The second grid contains the tens: 10, 20, 30, 40, 50, 60, 70, 80, 90.
- The third grid contains the ones: 1, 2, 3, 4, 5, 6, 7, 8, 9.
- To form a number like 999, you combine 900 (from the first grid), 90 (from the second grid), and 9 (from the third grid).
- Each number in the large grid is formed by adding one number from each of the three smaller grids.
- For example, 919 = 900 + 10 + 9, 922 = 900 + 20 + 2, and so on.
- The goal is to understand that any three-digit number can be broken down into its hundreds, tens, and ones place values.
