Understanding the Area Model

Mr. Neran introduces a lesson on multiplying multi-digit numbers using the area model, aligned with the fifth-grade standard NBT B5. The lesson reviews the process of breaking down numbers by place value and calculating the area of smaller rectangles to find the product of 624 and 35. The final step involves adding these areas to get the total product, which is 2,840.

What is the main objective of the lesson introduced by Mr. Neran?

• To practice subtraction of large numbers

• To explore division techniques

• To understand the area model for multiplication

• To learn addition of multi-digit numbers

Which grade standard is being reviewed in this lesson?

• Fourth grade

• Fifth grade

• Seventh grade

• Sixth grade

How is the number 624 broken down for the area model?

• 600, 24

• 600, 20, 4

• 6, 2, 4

• 60, 24

What are the place values used to break down the number 35?

• 35, 0

• 3, 5

• 30, 5

• 300, 50

Why is the method called the 'area model'?

• Because it uses addition

• Because it calculates the perimeter

• Because it finds the area of a rectangle

• Because it involves subtraction
