About this worksheet
A free printable 100 addition facts timed test with an answer key. How many can you solve in 5 minutes? Write your time at the bottom. First graders can do it on their own once they know the strategy at the top of the page. Have your child say each fact out loud while writing the answer.
On this sheet
52 problems, starting with 2 + 4, 6 + 0, 8 + 1, 4 + 5, 1 + 8, 0 + 1, 8 + 2, 3 + 3, 0 + 10, 7 + 2, 3 + 4, 1 + 0, 5 + 2, 2 + 7, and 38 more. The answers to all of them are on page 2.
Tips for using it
- Set a timer for 5 minutes and write your score at the bottom, then try to beat it next time.
- Skip the hard ones on the first pass and come back to them at the end.
- Use small objects like buttons or cereal to check tricky problems.
- Teach the make-10 trick early: 8 + 5 is the same as 8 + 2 + 3 = 13.
Printing tips
Download the PDF and print at 100% (or “fit to page” on A4). Page 1 is the worksheet and page 2 is the answer key with the answers in red; print just page 1 if you want to keep the answers for checking. The PNG shows page 1 only. Free for personal, family and classroom use.
