Multiplying Whole Numbers Using Base Ten Blocks

This video tutorial demonstrates how to multiply whole numbers using base ten blocks and area models. It begins by defining the blocks: one block (bit), ten block (long), and one hundred block (flat). The example of multiplying 17 by 15 is used, with 17 modeled vertically and 15 horizontally, forming a rectangle. The video explains how to fill this rectangle with base ten blocks and calculate the total area, which equals the product of 17 and 15. It also covers the concept of partial products, showing how they relate to the areas of the blocks used. The tutorial concludes by comparing the calculated areas to the partial products, illustrating how base ten blocks can help visualize multiplication and partial products.

• Long
