Multiplication Strategies: Using Area Models to Solve Complex Problems

This lesson teaches how to multiply a three-digit number by a one-digit number using an area model. The process involves breaking down the three-digit number into its place values, using the area model to visualize the multiplication, and then calculating and adding the products. The lesson emphasizes the importance of expanded notation and provides a step-by-step guide to using the area model effectively.

What is the primary benefit of using an area model for multiplication?

• It is faster than traditional multiplication.

• It eliminates the need for addition.

• It helps visualize and organize the multiplication process.

• It makes the numbers smaller.

When using an area model, how should a three-digit number be broken down?

• Into hundreds, tens, and ones.

• Into even and odd numbers.

• Into prime and composite numbers.

• Into multiples of ten.

In the example provided, what is the product of 300 and 7?

• 420

• 2,100

• 3,000

• 56

What is the next step after calculating the partial products in an area model?

• Subtract the smallest product.

• Multiply the products together.

• Add the partial products together.

• Divide the largest product by the smallest.

What is the final result of multiplying 368 by 7 using the area model?

• 3,000

• 2,520

• 2,576

• 2,100
