About this chart

Five ways to solve a fact you don't know yet, with an example for each.

What kids practice

By the end of second grade, kids should know every addition fact up to 9 + 9 without counting, and subtract within 20 quickly. In first grade they learned the facts one kind at a time. Now the facts are mixed, so the first job is to read the sign, and the second is to pick a fast way to solve it.

Watch for

  • Adding when the sign says subtract, especially after a row of addition problems.
  • Counting on fingers for facts they already know. Ask "do you know this one by heart?" first.
  • In take back to 10, taking away the whole bottom number from the teen number in one step and losing track.

It's free to print, as many copies as you need. See the full addition and subtraction facts to 20 guide for 2nd grade.
