About this chart

A fact family house, how to find a missing number, and what the equals sign means, with true and false examples.

What kids practice

A fact family is three numbers that make two addition facts and two subtraction facts, like 6, 8 and 14. Once kids see that, they can find a missing number in a problem like 6 + ? = 14 or ? - 8 = 6. They also learn what the equal sign really means. It says both sides are the same amount, not "the answer goes next".

Watch for

  • Adding every number they see, so 5 + ? = 12 gets the answer 17.
  • Thinking an equation must have the answer on the right, so 9 = 4 + 5 looks "wrong".
  • Putting the smaller number first in a subtraction fact.

It's free to print, as many copies as you need. See the full fact families and missing numbers guide for 1st grade.
