📓 3-4: Use Area Models and Partial Products to Multiply

Front

What is an area model in multiplication?

Back

An area model is a visual representation of multiplication that shows how to break numbers into parts to make the multiplication process easier.

Front

What does 'partial products' mean in multiplication?

Back

Partial products are the results of multiplying each digit of one number by each digit of another number, and then adding those results together.

How do you use an area model to multiply 34 x 6?

Back

Break 34 into 30 and 4. Multiply 30 x 6 = 180 and 4 x 6 = 24. Then add 180 + 24 = 204.

Front

What is the equation for multiplying 34 by 6 using partial products?

Back

(30 x 6) + (4 x 6) = 180 + 24 = 204.

What is the result of 29 x 9?

Back

261.

Front

How do you break down the multiplication of 92 x 9 using partial products?

Back

(90 x 9) + (2 x 9) = 810 + 18 = 828.

Front

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

Back

Break each number into tens and ones.

Front

What is the purpose of using area models in multiplication?

Back

To help visualize the multiplication process and understand how numbers can be broken down.
