This document discusses place value and how the value of each digit in a number depends on its position. It defines place value as the worth of a digit based on its place in a number. Examples are given to illustrate how the same digit, like 5, can have different values depending on if it is in the ones, tens, hundreds, etc. place. Place value charts are introduced to help visualize numbers and identify the correct positional value of each digit. Several examples are provided of writing out numbers in place value chart form. Students are then asked to identify the place value and value of underlined digits in various numbers.
