Solving 2-Digit by 2-Digit Multiplication Using the Partial Products Method

The video tutorial explains how to solve two-digit by two-digit multiplication problems using the partial products method. It begins by discussing the value and place of digits in numbers, using the number 65 as an example. The tutorial then demonstrates how to set up multiplication problems based on the place and value of each digit. It provides a detailed example of solving the multiplication problem 39 * 45 using the partial products method, breaking down the process into smaller, manageable steps. The lesson concludes with a recap of the key concepts covered.

What is the expanded form of the number 65?

• 60 + 5

• 50 + 6

• 6 + 50

• 65 + 0

In the partial products method, what do you multiply the ones place of one number by?

• The ones and tens place of the other number

• The tens place of the same number

• The tens place of the other number

• The ones place of the other number

When setting up multiplication problems using the partial products method, which of the following is a correct multiplication setup for 65 * 78?

• 60 * 78, 5 * 78, 70 * 65, 8 * 65

• 60 * 70, 60 * 8, 70 * 5, 8 * 5

• 60 * 5, 70 * 8, 5 * 8, 70 * 60

• 65 * 70, 65 * 8, 70 * 65, 8 * 65

What is the first step in solving a multiplication problem using the partial products method?

• Add the numbers together

• Multiply the numbers directly

• Break up the value of the digits

• Subtract the smaller number from the larger one
