Make single digit addition worksheets from the 100 facts between 0 + 0 and 9 + 9. The page opens on 30 mixed facts; other sheets keep to sums to 10, sums past 10, or one strategy.

Which one digit addition worksheets to print, and when
Print All 100 facts, 0 + 0 to 9 + 9 once, as a baseline. Repeat Sums to 10 only, 30 to a page until it is quick. Then print Sums 11 to 18, crossing ten, and Both addends 6 to 9, the 16 large facts for the slowest corner of the table. Plus 9 facts, add 10 and step back and Plus 8 facts, make ten first each drill one way through those facts.
Teach Plus 9 facts before Plus 8 facts: taking 1 back is a smaller step than splitting off 2.
All 100 facts prints only at 100. For a shorter check, set the Timed page to 30 problems.
Questions and answers
How many single-digit addition facts are there?
100, from 0 + 0 to 9 + 9. Of those, 64 have a sum of 10 or less and 36 cross ten. Counting 3 + 8 and 8 + 3 as one fact leaves 55.
What grade are single digit addition facts for?
Grades 1 and 2. Common Core 1.OA.6 has grade 1 add within 20 and be fluent within 10. By the end of grade 2, pupils should know from memory all sums of two one-digit numbers (2.OA.2).
What comes after single digit addition?
Next step: sums up to 20, teen numbers allowed is the bridge to 2-digit addition. After that, the free addition worksheets page has a regrouping ladder that starts with a 2-digit number plus a 1-digit number.
All 16 sheet types
Mixed fact pages, 12 to 100 problems 4
All 100 facts, 0 + 0 to 9 + 9Ten digits added to ten digits give 100 addition facts, from 0 + 0 up to 9 + 9 = 18. This page prints each of them once, shuffled. Use it as a baseline at the start of a term, not as daily practice.
Mixed single-digit facts, 30 to a pageThirty facts drawn from 1 + 1 to 9 + 9, written side by side, with no fact twice on a page: 7 + 8 = 15 sits beside 3 + 4 = 7. Five rows of 6 leave room to write, and the answer key prints on its own page.
Mixed single-digit facts, 50 to a page, stackedThe same mix with one number written above the other, 50 to a page in 5 rows of 10, so 6 + 9 = 15 becomes a small column with a line under it. Stacked facts get pupils used to the layout that 2-digit addition needs later.
Timed page, 60 facts with a time lineSixty mixed facts such as 4 + 7 = 11, with a line for the time taken printed beside Name, Date and Score. Write down the time and not a pass mark: a pupil's own time from last week is the only fair number to beat.

Facts sorted by the size of the sum 6
Both addends 6 to 9, the 16 large factsSixteen facts have two large addends, such as 7 + 9 = 16. A page of 32 brings each of them round twice, in a new order each time. Print it for pupils who are quick up to 10 and slow only at this end of the table.
Next step: sums up to 20, teen numbers allowedNot every problem here is single digit: 13 + 4 = 17 can sit beside 8 + 9 = 17. The sheet covers the whole range grade 1 adds in, sums within 20 (1.OA.6), and it is the bridge from single facts to 2-digit addition.
Small facts, 1 + 1 to 5 + 5The 25 facts with both numbers 5 or less, such as 4 + 3 = 7. No sum passes 10, and each addend fits on one hand, so a pupil can check any answer with fingers. A good first page of bare numbers after counters and pictures.
Sums 11 to 18, crossing tenOnly the 36 facts whose sum passes 10, from 2 + 9 up to 9 + 9, such as 8 + 5 = 13. These are the facts that still need a strategy after the small ones are known, so they earn pages of their own, 30 at a time.
Sums to 10 in small columns, 20 to a pageThe facts within 10 again, this time stacked, 20 to a page: 6 + 3 = 9 with the 3 under the 6 and a line below. Have pupils say the top number and count on the bottom one, the habit every longer column sum relies on.
Sums to 10 only, 30 to a pageEvery sum is 10 or less and neither number is 0: 4 + 5 = 9, then 7 + 3 = 10. The Common Core asks grade 1 for fluency within 10 (1.OA.6), so this is the sheet to repeat until it is quick. No fact comes twice on a page.
One addend at a time 6
Plus 1 and plus 2, count onOne addend is always 1 or 2, so every answer is the next number or the one after it: 7 + 2 = 9. The Common Core describes the link between counting and adding in these words: counting on 2 to add 2 (1.OA.5).
Plus 5 factsOne addend is always 5: 5 + 8 = 13. Split the other number into 5 and the rest, and the two fives make a ten, so 5 + 5 + 3 = 10 + 3 = 13. It is the same as showing a whole hand, then another hand and 3 more fingers.
Plus 8 facts, make ten firstOne addend is always 8. Take 2 from the other number to fill the ten: 8 + 6 = 14 because 8 + 2 + 4 = 10 + 4 = 14. Common Core 1.OA.6 explains making ten with this very sum, and Texas 1.3(D) names the strategy too.
Plus 9 facts, add 10 and step backOne addend is always 9. Add 10 to the other number, then take 1 away: 9 + 6 = 15 because 10 + 6 − 1 = 15. A whole page of the same move gives it time to turn into a habit and replace counting on from 9.
Small number first, start from the largerThe small addend is always printed first: 2 + 9 = 11. Counting on from 2 takes nine steps, and counting on from 9 takes two. The sheet trains pupils to find the larger number and start there, wherever it stands in the problem.
Zero facts, 0 + 0 to 9 + 0Nineteen of the 100 facts have a zero in them, such as 0 + 7 = 7, its turn-around 7 + 0 = 7, and 0 + 0 = 0. Adding zero leaves a number as it was. A page of nothing else makes that rule plain enough to stop costing time.
How this list was compiled: Sheet types, wording and worked examples are own work. Every worked example was computed twice by script on 2026-09-19, and the counts of facts (100 in all, 55 without turn-arounds, 45 with sums to 10 and no zeros, 36 with sums from 11 to 18, 25 small facts, 19 with a zero, 16 with both addends from 6 to 9, 6 ways to make 13) were counted by script the same day. Standard numbers and the wording taken from them were checked 2026-09-19 against the full text of the Common Core State Standards for Mathematics (California Department of Education copy, https://www.cde.ca.gov/be/st/ss/documents/ccssmathstandardaug2013.pdf): 1.OA.3 to 1.OA.8, 2.OA.2 and 3.OA.9; and against the Texas Essential Knowledge and Skills for Mathematics, 19 TAC 111.3 Grade 1 and 111.4 Grade 2, adopted 2012 (https://tea.texas.gov/sites/default/files/ch111a.pdf): 1.3(D), 1.5(E), 1.5(F), 1.5(G) and 2.4(A). Checked 2026-09-19 against Wikipedia: the 100 single-digit addition facts and the addition table, the cut from 100 facts to 55 by the commutative property, counting on, adding zero and making ten, https://en.wikipedia.org/wiki/Addition . The sheets follow no single curriculum, and naming a standard here does not mean a sheet is approved by anyone. Licence: own work
