Place value You studied place value in Grade 4. Do you still remember how to use place value? Do some quick revision. Place value helps us to determine the value of a digit. Our number system (the numbers we work with) contains digits from 0 to 9 only. What do we do when we must work with numbers greater than 9?
We use place value to indicate when we are working with numbers greater than 9. It means that the value of a digit is determined by its place or position in a number.
When we work with place value, we can think of each value as a box with high walls.

In each box, you can find the digits 0 to 9. As soon as the number becomes greater than 9, it jumps over the wall into the next box.
