Multiplication Strategies and Models

Mrs. Heath Coe guides students through a Grade 4 mid-module review test using Engaged New York materials. The video covers multiplication using area models and place value strategies. It includes examples of multiplying numbers like 40 by 20, 5 by 324, and 7,052 by 6. The teacher emphasizes understanding place value and using partial products to ensure accuracy in calculations.

What is the primary purpose of using an area model in multiplication?

• To make the problem look more complex

• To confuse the students

• To visually break down the multiplication process

• To avoid using numbers
