Understanding Base Ten Blocks and Decimal Multiplication

The video tutorial explains how to multiply decimals using base ten blocks. It begins by defining the base ten blocks and demonstrates how to model four-tenths using these blocks. The tutorial then shows how to partition and shade the blocks to find the product of two-tenths times four-tenths, resulting in eight-hundredths. An alternative method of partitioning is also presented, and the video concludes with a summary of the process.

What does a ten-by-ten block represent in base ten blocks?

• One-tenth

• One-hundredth

• One whole
