Multiplying integers is repeated addition and can be modeled with the Integer Game. If 3 × a corresponds to whathappens to your score if you get three cards of value a, then (−3) × a corresponds to what happens to your score ifyou lose three cards of value a. Adding a number multiple times has the same effect as removing the opposite valuethe same number of times (e.g., a × b = (−a) × (−b) and a × (−b) = (−a) × b.)

One tool that you can use is our **multiplication / division **Mickey Mouse.

Cover up the two signs of the two integers that you are either multiplying or dividing, and the sign that is still visible is the sign that * belongs to your answer*.
