Mastering Partial Product Strategy for Multiplication

The video tutorial explains how to multiply a two-digit number by a one-digit number using the partial product strategy. It begins by aligning numbers vertically, similar to the traditional algorithm, but without regrouping. The method involves writing out the values of tens and ones separately, calculating their products, and then summing these partial products to get the final result. The tutorial emphasizes understanding the connection between this method and the area model, encouraging students to practice without using geometric shapes.

What is the first step in the partial product strategy for multiplying a two-digit number by a one-digit number?

• Regrouping the numbers

• Lining the numbers up vertically

• Adding the numbers together

• Drawing a rectangle
