About this worksheet
Twenty mixed addition and subtraction facts within 20 for first grade (14 + 5, 17 - 9, 8 + 8), two columns with a blank for each answer and a garland of Christmas pictures along the bottom. Addition and subtraction are shuffled so children read the sign every time. A score line and the answer key on page 2 make it easy to check. First graders can do it on their own once they know the strategy at the top of the page. Red, green and gold make a classic Christmas palette.
On this sheet
20 problems, starting with 18 - 13 = ___, 5 + 13 = ___, 8 - 1 = ___, 2 + 2 = ___, 2 + 14 = ___, 14 - 5 = ___, 8 - 2 = ___, 5 + 6 = ___, 14 - 13 = ___, 15 - 8 = ___, 8 + 2 = ___, 4 + 12 = ___, 9 - 7 = ___, 20 - 8 = ___, and 6 more. The answers to all of them are on page 2.
Tips for using it
- Check each answer by adding it back to the number taken away.
- Count back on your fingers or the number line for the hardest facts.
- Have your child say each fact out loud while writing the answer.
- Make a three-page packet per child: one word search, one maze and one math or reading page at their level. It fills a quiet 20 minutes.
