2 by 2 multiplication area model

Front

What is the area model in multiplication?

Back

The area model is a visual representation of multiplication that breaks down numbers into their place values to simplify the calculation.

Front

How do you represent 23 X 47 using the area model?

Back

Break down 23 into 20 and 3, and 47 into 40 and 7. Then, create a grid to find the partial products: (20x40), (20x7), (3x40), (3x7).

Front

What are partial products?

Back

Partial products are the results of multiplying each part of the numbers in a multiplication problem before adding them together to get the final product.

Front

Calculate the partial products for 23 X 47 using the area model.

Back

800 (20x40) + 140 (20x7) + 120 (3x40) + 21 (3x7) = 1080.

Front

What is the final product of 23 X 47?

Back

The final product is 1081.

Front

How do you represent 14 X 76 using the area model?

Back

Break down 14 into 10 and 4, and 76 into 70 and 6. Then, create a grid to find the partial products: (10x70), (10x6), (4x70), (4x6).

Front

Calculate the partial products for 14 X 76 using the area model.

Back

700 (10x70) + 60 (10x6) + 280 (4x70) + 24 (4x6) = 1060.

Front

What is the final product of 14 X 76?

Back

The final product is 1064.

Front

What is the area model used for in multiplication?

Back

The area model is used to visualize and simplify the multiplication of larger numbers by breaking them into smaller, more manageable parts.

Front

What is the significance of place value in the area model?

Back

Place value helps to organize numbers into tens, hundreds, etc., making it easier to calculate partial products.
