Multiplying Using Box method (Also known as open array model)

This video is to help model how to use the box method (open array model) for multiplication. I have modeled the method using a two digit by one digit number (2x1) and three digit by one digit number (3x1) and a two digit by two digit number (2x2). In the state of NC these are the three types of multiplication problems your scholar will be expected to be able to do in the fourth grade.
