About this worksheet
Addition and subtraction facts mixed together on graph paper, so kids have to read the sign.
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, with Fewer, Standard or More on the page and an answer key. See the full addition and subtraction facts to 20 guide for 2nd grade.
