​

Box Method Models

Your model will look different depending on how many digits you are multiplying.

Which model do you think you would use for:

18 x 32?

4 x 53?

6 x 5,831?

Multiple Choice

3 x 24

Which of the following Box Method models will I need to use?

​We need two sections because 24 is a 2-digit number!

​3 x 24

Multiple Choice

How do I decompose 24 by place value?

• 20 + 4

• 20

• 24 + 3

• 10 + 4

• 10

Multiple Select

Select both (2) multiplication equations that will be used for this box method.

• 20 x 4 = 80

• 3 x 20 = 60

• 3 x 4 = 12

• 3 x 10 = 30

Multiple Choice

Next, we are going to add 60 and 12 together.

They are both called...

• products.

• partial products.

• the answer.

Multiple Choice

What is the product of 3 x 24?

• 72

• 60

• 12

• 324

• 62

Multiple Choice

5 x 148

Which of the following Box Method models will I need to use?

Multiple Choice

How do I decompose 148 by place value?

• 100 + 48

• 10 + 40 + 8

• 100 + 40 + 8

• 40 + 8

• 148 + 5

Multiple Select

Select the three (3) multiplication equations that will be used to solve this Box Method.

• 5 x 100 = 500

• 100 x 40 = 4,000

• 5 x 40 = 200

• 40 x 8 = 320

• 5 x 8 = 40

Multiple Choice

Now, we will add 500, 200 and 40 together.

They are called...

• large numbers

• partial products

• decomposing

• place value

• multiplication
