Place value is a system that groups numbers based on their size.
The position of a digit determines it's value. When we say numbers we group then within the same house. For example 15709 has fifteen thousand, seven hundredred nine ones.
Understanding our base 10 place value system allows us to prounce big numbers properly. It also allows us to identify numbers before and after.
