Multiplying Whole Numbers Using Base Ten Blocks

This video tutorial demonstrates how to multiply whole numbers using base ten blocks. It begins by defining the blocks: one block, ten block, and one hundred block. The tutorial models the numbers 12 and 14 using these blocks and calculates their product by visualizing the area of a rectangle formed by the blocks. The video also explains the partial products method by breaking down the multiplication into smaller, distributive steps. The tutorial concludes by comparing the two methods and highlighting the effectiveness of base ten blocks in visualizing multiplication and understanding partial products.

What is a 'one block' also known as?

• Long

• Cube

• Bit

• Flat
