Multiplying Multi-Digit Numbers 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 powers of 10 and common mistakes in multiplication. Two examples using the area model are provided: multiplying 23 by 15 and 225 by 12. Each example involves breaking numbers into expanded form, drawing a rectangle, and calculating partial products to find the final answer.
