Base Ten Blocks Addition Concepts

The video tutorial explains how to model the addition of two-digit whole numbers using base ten blocks. It begins with an introduction to the concept and then provides two examples: adding 36 and 15, and adding 36 and 28. In each example, the process of adding the ones and tens place values is demonstrated, including the exchange of one-blocks for ten-blocks when the sum exceeds ten. The tutorial emphasizes the visual representation of addition and the importance of understanding place value.
