Multiplication Using the Area Model

This video tutorial teaches how to multiply multi-digit numbers using the area model. It begins with a review of basic multiplication concepts, including the definition of a product, repeated addition, and arrays. The tutorial then explains the importance of understanding powers of ten and place value. It provides step-by-step instructions for multiplying 23 times 15 and 225 times 12 using the area model, breaking down numbers into expanded form and calculating partial products. The lesson concludes with a summary of the area model approach.
