## Grade 7 Mathematics Module 2, Topic B, Lesson 10 Student Outcomes

• Students practice and justify their understanding of multiplication of integers by using the Integer Game.  For example,  3 x 5 corresponds to what happens to your score if you get three 5 cards;  3 x (-5) corresponds to what happens to your score if you get three -5 cards; (-3) x 5 corresponds to what happens to your score if you lose three 5 cards; and (-3) x (-5) corresponds to what happens to your score if you lose three -5 cards.
• Students explain that multiplying by a positive integer is repeated addition and that adding a number multiple times has the same effect as removing the opposite value the same number of times (e.g.,  5 x 3 = (- 5) x (- 3) and  5 x (-3) = (-5) x 3.)
• Students use the properties and facts of operations to extend multiplication of whole numbers to multiplication of integers.
