Definition of Place Value. Each digit in a number has a value according to its place in the number. This value is called its place value (e.g. In the number 55, the first 5 from left has a place value of 10, while the second 5 from left has a place value of 1. Hence the number 55 can be represented as 50 + 5).

We use the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 to write any whole number. The symbols are called digits. Digits have different values depending on their position in the number.
How do you introduce place value lessons?
Explain that you are going to say a number and you want them to show that number using ones and tens. Begin with single digit numbers. After they have had practice moving cubes onto their workspace, begin building 2-digit numbers. Have them place 1 ten and 2 ones on their board.
