This video starts where part 1 left off. They start with using subtraction to find the product of two numbers. For example, 7 x 8 = ?, I know 7 x 10 = 70, then I subtract 14 to get 56, need to look at the pattern that is occuring. Review what multiplication means, repeated addition. Then they move on to two digit numbers mulitplied by a two digit number, using a number line. They do this with a number of different problems. Video is good quality and good for all students as review or initial learning of the concept.
