Partial Products Method in Multiplication

This video tutorial teaches how to solve two-digit by two-digit multiplication problems using the partial products method. It begins with an introduction to the concept, followed by an explanation of place value and expanded form. The tutorial then demonstrates how to set up multiplication problems based on the place and value of each digit. Finally, it provides a step-by-step example of solving a multiplication problem using the partial products method.
