Unformatted text preview: Inverse Operation  An opposite operation that undoes another. 4 x 8 = 32 32 / 4 = 8 Multiplication/Division Fact Families are found by: Starting with a simple multiplication fact. ( 3 x 9 = 27 ) Changing the multiplicands around. ( 9 x 3 = 27 ) Writing the Inverse operations for both. ( 27 / 3 = 9 & 27 / 9 = 3 ) What are the 4 members of the Fact Family of 3 x 7 = 21? 3 x 7 = 21 7 x 3 = 21 21 / 3 = 7 21 / 7 = 3 What are the 4 members of the Fact Family of 6 x 4 = 24? 6 x 4 = 24 4 x 6 = 24 24 / 6 = 4 24 / 4 = 6 What are the 4 members of the Fact Family of 7 x 8 = 56? 7 x 8 = 56 8 x 7 = 56 56 / 7 = 8 56 / 8 = 7 What are the 4 members of the Fact Family of 9 x 7 = 63? 9 x 7 = 63 7 x 9 = 63 63 / 9 = 7 63 / 7 = 9 What are the 4 members of the Fact Family of 6 x 7 = 42? 6 x 7 = 42 7 x 6 = 42 42 /6 = 7 42 / 7 = 6...
