Understanding Base 10 Number Models

The video tutorial explains how to use base 10 blocks to represent numbers in different ways. It covers the representation of numbers 24, 120, and 206 using base 10 blocks, demonstrating how to break down and reassemble these numbers using units, rods, and flats. The lesson emphasizes understanding the value of each block and how they can be traded to show the same number in various forms.
