The instructor explains how to represent these numbers visually using drawings, such as squares for hundreds and dots for tens and ones. The video includes examples, like the number 246, to illustrate the process of organizing numbers in a chart and drawing them accurately. The lesson aims to help students grasp the concept of place values and how to represent numbers without physical manipulatives.
