Introducing 10,000

The greatest 1-digit number is .

The greatest 2-digit number is .

The greatest 3-digit number is .

Similarly, the greatest 4-digit number is .

Let us increment the Greatest Numbers:

Let us assume that each box can contain at most 9 dots. As you can see the last box has dots. Lets see what happens when we add one more dot to it. Click somewhere in the 1s cell to add 1:

9 + 1 = .

This shows the transition from the greatest single-digit number to the smallest double-digit number. Here, 10 = 10 × 1.

99 + 1 = .

This demonstrates the transition from the greatest double-digit number to the smallest triple-digit number. Here, 100 = 10 × 10.

999 + 1 = .

This indicates the transition from the greatest triple-digit number to the smallest quadruple-digit number. Here, 1000 = 10 × 100.

By extending the pattern, adding 1 to the greatest 4-digit number (9999) results in the smallest 5-digit number.

9999 + 1 = .

The new number, 10000, called as ten thousand is the first 5-digit number, marking a new level in place value. Additionally, 10000 = 10 × 1000, adhering to the observed pattern.

These patterns demonstrate how numbers progress from one place value category to the next, emphasizing the importance of place value in understanding the number system.
