Exploring Area Models for Multiplying Fractions

In this video, Mr. War introduces a math lesson on multiplying fractions using area models. The lesson involves a hands-on activity where students fold paper to visualize fractions and their products. Mr. War guides students through shading and overlapping sections to find the product of two fractions. The video also explores alternative methods for solving fraction problems and concludes with final thoughts and a farewell.

What is the essential question of the lesson?

• How can you subtract fractions using a visual model?

• What is the sum of two fractions?

• How can you divide fractions using a number line?

• How can you use an area model to show the product of two fractions?
