Integer multiplication and division are not hard to teach. We can tell our students the rules and for the most part, they can apply those rules. But wait! Do they know why these “magical” rules exist? Is a negative times a negative positive only because some math magician said so?
Just like the title implies, students will get the chance to investigate in Investigating Patterns of Integer Multiplication and Division. By observing, studying, and predicting patterns, they will uncover the secrets of integer multiplication.
And that’s not all. Students get the opportunity to see how inverse operations and fact families connect integer multiplication to integer division rules.
