Place Value Exercise: Finding Numbers with 3 in Tens Position

Q: How do I remember which position is tens?

Start counting from the right: the first digit is ones, second is tens, third is hundreds. The tens digit is always the middle digit in 3-digit numbers!

Q: What if a number has 0 in the tens place?

Zero counts as a digit too! In $ 303 $, the tens digit is 0, not 3. Don't skip over zeros when identifying positions.

Q: Why isn't 303 correct if it has two 3s?

Position matters more than repetition! In $ 303 $, the 3s are in the hundreds and ones positions, but the tens position has a 0.
