Fact Families


Videos and songs to help Kindergarten and Grade 1 kids learn the Fact Families.

Fact Families will help them to apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.

Common Core: 1.OA.4

Learning Targets:

  • I can use properties of operations to add and subtract.
  • I can give an example and explain how a subtraction equation can be rewritten as an addition equation.
  • I can rewrite a subtraction equation as an addition equation with a missing addend.
  • I can connect addition to subtraction (Inverse Operation)
  • I can apply the strategy to think addition rather than take away:
    Rather than 9 - 6 = ___ ask how many would you add to six to equal nine?
  • I can use concrete models with manipulatives to find the unknown
