Fact Families:  Fact Families By Monica Yuskaitis Definitions:  Definitions Addend - Any number being added. 6 + 5 = 11 Inverse Operation - An opposite operation that undoes another. 5 + 4 = 9 9 - 5 = 4 Addition/Subtraction Fact Families are found by::  Addition/Subtraction Fact Families are found by: Starting with a simple addition fact. ( 2 + 5 = 7) Changing the addends around. (5 + 2 = 7) Writing the Inverse operations for both. (7 - 2 = 5 andamp; 7 - 5 = 2) What are the 4 members of the Fact Family of 3 + 4 = 7?:  What are the 4 members of the Fact Family of 3 + 4 = 7? 3 + 4 = 7 4 + 3 = 7 7 - 3 = 4 7 - 4 = 3 What are the 4 members of the Fact Family of 8 + 1 = 9?:  What are the 4 members of the Fact Family of 8 + 1 = 9? 8 + 1 = 9 1 + 8 = 9 9 - 8 = 1 9 - 1 = 8 What are the 4 members of the Fact Family of 11 + 5 = 16?:  What are the 4 members of the Fact Family of 11 + 5 = 16? 11 + 5 = 16 5 + 11 = 16 16 - 11 = 5 16 - 5 = 11 What are the 4 members of the Fact Family of 9 + 7 = 16?:  What are the 4 members of the Fact Family of 9 + 7 = 16? 9 + 7 = 16 7 + 9 = 16 16 - 9 = 7 16 - 7 = 9 What are the 4 members of the Fact Family of 12 + 7 = 19?:  What are the 4 members of the Fact Family of 12 + 7 = 19? 12 + 7 = 19 7 + 12 = 19 19 - 12 = 7 19 - 7 = 12 Definitions:  Definitions Factors - The numbers being multiplied. 4 x 8 = 32 Inverse Operation - An opposite operation that undoes another. 4 x 8 = 32 32  4 = 8 Multiplication/Division Fact Families are found by::  Multiplication/Division Fact Families are found by: Starting with a simple multiplication fact. ( 3 x 9 = 27) Changing the factors around. (9 x 3 = 27) Writing the Inverse operations for both. (27  3 = 9 andamp; 27  9 = 3) What are the 4 members of the Fact Family of 3 x 7 = 21?:  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?:  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?:  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?:  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?:  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
