Box Method Multiplication: 2-Digit Challenges

This video tutorial by Mr. J explains the box method for multiplying larger numbers. The method is similar to the traditional standard algorithm but offers a different setup to enhance understanding. The video includes two examples: multiplying 52 by 23 and 85 by 49, demonstrating the step-by-step process of drawing boxes, expanding factors, multiplying, and adding partial products to find the final answer.

What is the first step in using the box method for multiplication?

• Expanding the factors

• Drawing and splitting the box

• Adding the partial products

• Multiplying the expanded factors
