Supposed you model numbers with three digits, but you do not use any tens blocks. What digit must be in the standard form of every number you model? Give examples and explain
If you are modeling numbers with three digits but not using any tens blocks, it means that you can only use units (ones) and hundreds blocks. This leaves out the tens place, which usually determines the value of a number. In this case, the digit that must be in the standard form of every number you model is the digit in the hundreds place.
Examples:
- The number 100: In the standard form, the digit in the hundreds place is 1. Even though there are no tens blocks, we still need to specify the value of the hundreds place.
- The number 200: Similarly, in the standard form, the digit in the hundreds place is 2. Again, no tens blocks are present.
- The number 300: Likewise, the digit in the hundreds place is 3.
By focusing on the hundreds place, you can still represent and understand the value of three-digit numbers, even without the use of tens blocks.
