Lesson notes

Understanding Place Value

Place value is the value of a digit based on its position in a number. For numbers up to 1000, we have three main place values: Hundreds (H): The digit in this place tells us how many hundreds there are. For example, in 345, the '3' represents 300. Tens (T): The digit in this place tells us how many tens there are. For example, in 345, the '4' represents 40. Ones (O): The digit in this place tells us how many ones there are. For example, in 345, the '5' represents 5.

Example 1: The number 287 Hundreds: 2 (200) Tens: 8 (80) Ones: 7 (7)

Therefore, 287 is 200 + 80 + 7.
