Multiplication Using Area Model

This video tutorial teaches how to multiply a three-digit number by a one-digit number using an area model. The lesson explains the importance of breaking down numbers into their place values and using expanded notation to simplify complex multiplication. By visualizing the problem with an area model, students can organize their thinking and accurately calculate the product. The tutorial provides a step-by-step example, demonstrating how to multiply each part of the expanded number and then sum the results to find the final product.

What is the primary benefit of using a visual aid like the area model in multiplication?

• It helps in organizing and visualizing the problem.

• It simplifies division problems.

• It makes the numbers smaller.

• It eliminates the need for addition.

Why is it important to break down a double-digit number into its place values?

• To avoid using multiplication altogether.

• To use extended facts for easier multiplication.

• To simplify the addition process.

• To make the number larger.

What is the first step in setting up an area model for multiplication?

• Drawing a circle.

• Entering the large rectangle.

• Writing the final product.

• Adding all numbers together.

How should the rectangle be divided when setting up the area model?

• Into two equal parts.

• Into sections for hundreds, tens, and ones.

• Into four parts for each digit.

• Into a single section for simplicity.

What is the result of multiplying 300 by 7 in the area model?

• 2520

• 56

• 420

• 2100

How do you calculate the product of 60 times 7 using extended facts?

• By multiplying 6 by 7 and then by 10.

• By adding 60 seven times.

• By subtracting 7 from 60.

• By dividing 60 by 7.

What is the final step after calculating individual products in the area model?

• Dividing the total by the number of sections.

• Adding all the sections together.

• Multiplying all products together.

• Subtracting the smallest product.

What is the total product of 7 groups of 368 using the area model?

• 360

• 2100

• 2576

• 2520

What is the purpose of reviewing the area model after solving the problem?

• To find mistakes in addition.

• To ensure the model is drawn correctly.

• To confirm the total product is accurate.

• To change the numbers used in the model.

What have you learned in this lesson about multiplying a three-digit number by a one-digit number?

• How to avoid using multiplication.

• How to add numbers quickly.

• How to use an area model to organize multiplication.

• How to divide numbers easily.
