This video lesson is aligned to Lesson 3.3 in the Grade 4 Go Math on Investigating Area Models and Partial Products. In this lesson, students break factors of a multiplication problem apart by place value; then students create a diagram to organize the partial products and find their sum. Drawing diagrams is a valuable tool for students and has several benefits: They organize the information, and they visualize the relationship of the information. This model illustrates the Distributive Property, which is the underlying concept of the multiplication algorithm. This video is 9 minutes 39 seconds in length.
This video can be used in the classroom or posted on a teacher's website to be viewed at home to reinforce instruction. Great for students to view while doing homework, studying for test, or to stay up to date while absent. It is also great for parents who have a difficult time understanding the methods and concepts taught with the Common Core Mathematics Standards.
