Place value helps students understand how numbers are built and the value of each digit. This strengthens number sense and helps students understand expanded form, compare numbers, and solve addition and subtraction problems with larger values.

Understanding Place Value: Hundreds, Tens, and Ones (Lesson)

In a three‑digit number, we read the digits from left to right as the hundreds place, the tens place, and the ones place.

For example, in the number 364:

  • The 3 is in the hundreds place, so it represents 300
  • The 6 is in the tens place, so it represents 60
  • The 4 is in the ones place, so it represents 4

When we add these values together, we get:
300 + 60 + 4 = 364
