Add & subtract within 20

🖨️ Print a worksheet — three levels

The same add & subtract within 20 worksheet at three levels, so every group in your class works on the same page: Below grade (smaller numbers, fewer steps), On grade (1st Grade, 1.OA) and Above grade (bigger numbers or an extra step). Each level comes with its own answer key page, a name and date line, and prints on US Letter. Free and unlimited — press New set for fresh questions.

Every sheet has a QR code that opens the same set online: kids type their answers and check them, and parents can see the answer key. The set code at the bottom of the page reprints the exact same sheet later.
