How the 55 one-digit facts break down
Nineteen follow two zero rules: take away 0 and the number stays, take away all and 0 is left. Another 26 sit 1 or 2 counts from the answer: count back for 8 − 2, up for 9 − 7. The 10 facts left for memory prints the rest: 19 + 26 + 10 = 55.
One digit subtraction worksheets in a working order
Print All 55 one-digit facts, once each and circle the slow ones. Find each under Facts sorted by strategy, or print Every fact from 9, 8, 7 or 6. Then time the opening page. Common Core 1.OA.6 asks grade 1 for fluency within 10.
Write the time on the Time line and compare it with the pupil's own last page, never with the class.
Once 6 − 0 and 6 − 6 are instant, stop printing the zero sheets: the opening page has none.
When 9 − 5 will not stick, ask what goes with 5 to make 9.
Questions and answers
How many single digit subtraction facts are there?
There are 55 when no answer may be negative: 10 start from 9, 9 start from 8, and so on down to 0 − 0. Leave out every fact with a 0 in it and 36 remain.
Why do some sheets go past 9, as far as 18 − 9?
One-digit sums reach 9 + 9 = 18, so the facts that undo them start from up to 18. Those 45 facts from 10 and the teens bring the list to 100. Common Core 2.OA.2 expects the sums from memory in grade 2.
Is there a page of 100 single digit subtraction problems?
Yes. Choose 100 under Problems on the opening sheet for a no-zero page where facts come round again, or print All 100 basic facts, 0 − 0 to 18 − 9, with every fact once. Both have a Time line.
Can I print the facts side by side instead of stacked?
Yes. Side by side, 30 facts across prints the opening sheet's facts in a line, 7 − 6 = 1, and offers 50 or 100 too. Answer on the left, equals sign first turns each fact round: ___ = 8 − 7.

The one-digit facts, mixed 4
The 36 facts with no zero, once eachThe same check without the easy marks: all 36 facts where at least 1 is taken away and at least 1 is left, from 2 − 1 to 9 − 8, once each. 8 − 3 = 5 is on every copy of this page, and only the order changes. Score it out of 36.
All 55 one-digit facts, once eachEvery fact from 0 − 0 to 9 − 9 that has no negative answer, printed once and shuffled: 55 in all, with zero facts such as 7 − 7 = 0 and 8 − 0 = 8 included. One page shows which facts a pupil knows and which are still counted on fingers. Score it out of 55.
Bigger numbers only, starting from 6 to 9Twenty facts that all start from 6, 7, 8 or 9, such as 9 − 6 = 3, with no repeats and no zeros. There are 26 facts of this kind, and a pupil who counts on fingers has the furthest to count here. Print it when the small facts are quick and the mixed page still drags.
Mixed one-digit facts, no zerosThe opening sheet: 30 stacked facts such as 9 − 4 = 5, dealt without repeats from the 36 facts where neither the number taken away nor the answer is 0. The header has Name, Date, Score and Time. Press New sheet for another 30, or choose 50 or 100 problems.

Zero facts: minus 0 and a number minus itself 3
A number minus itself, 0 − 0 to 9 − 9The 10 facts where everything is taken away, each printed twice at the opening count, such as 4 − 4 = 0. It looks like the minus 0 rule and gives the opposite answer, so it is worth one lesson right beside that sheet. Every answer on the key is 0, and a pupil who spots that has learned the rule.
Both zero rules mixed, 19 factsAll 19 one-digit facts with a 0 in them, once each: 10 that take away 0, 10 that leave 0, and 0 − 0 counted once because it is both. 5 − 5 = 0 and 5 − 0 = 5 sit on the same page, which tests whether the two rules are really separate in a pupil's head.
Minus 0 facts, 0 − 0 to 9 − 0The 10 facts that take away nothing, each printed twice at the opening count, in two shuffled rounds. The rule fits in one sentence: subtracting 0 leaves the number as it was, so 6 − 0 = 6. Print it once to teach the rule, then spend the drill time on facts that need it.
Facts sorted by strategy 3
The 10 facts left for memoryTake out the 19 zero facts and the 26 that sit 1 or 2 counts from the answer, and 10 remain: 6 − 3, 7 − 3, 7 − 4, 8 − 3, 8 − 4, 8 − 5, 9 − 3, 9 − 4, 9 − 5 and 9 − 6. At 20 problems each is printed twice, so 8 − 5 = 3 turns up in both halves.
Count back 1 or 2The 15 facts that take away 1 or 2, once each. The answer is the next number down or the one after it: for 8 − 2 = 6, say 7, 6. The Common Core ties counting to subtraction in grade 1 (1.OA.5). Counting back further than 2 is slow, so the other sheets in this group teach other ways.
Count up, answers of 1 or 2When the two numbers are close, count up from the smaller one. For 9 − 7 = 2, start at 7 and say 8, 9: two counts, so the answer is 2. All 15 one-digit facts with an answer of 1 or 2 are here, once each. Counting back 7 from 9 reaches the same answer the long way.
Every fact from one number 4
Every fact from 6, in order then shuffledSeven facts, 6 − 0 to 6 − 6, in order and then shuffled, 14 problems at the opening count. Two are zero facts, two count back (6 − 1 and 6 − 2) and two count up (6 − 5, and 6 − 4 = 2). Only 6 − 3 is left, and it is half of 6, so this page has one new fact to learn.
Every fact from 7, in order then shuffledEight facts, 7 − 0 to 7 − 7, in order and then shuffled, 16 problems at the opening count. Seven is odd, so no fact here is its own partner: the 8 facts make 4 pairs, and 7 − 4 = 3 goes with 7 − 3. A pupil who can name the partner of each fact has halved the list.
Every fact from 8, in order then shuffledNine facts, 8 − 0 to 8 − 8, in order and then shuffled, 18 problems at the opening count. Eight has a middle fact, 8 − 4 = 4, where both parts match; the others pair off around it, 8 − 3 with 8 − 5 and 8 − 2 with 8 − 6. Ask which fact on the page is its own partner.
Every fact from 9, in order then shuffledThe 10 facts that start from 9. At 20 problems, the first 10 run in order, 9 − 0, 9 − 1, 9 − 2 and on, so the pupil sees the answer fall by 1 each time; the last 10 shuffle the same facts. 9 − 3 = 6 and 9 − 6 = 3 use one pair of parts, so each fact learned is two.
Timed pages and other layouts 2
Answer on the left, equals sign firstEach fact is printed the other way round, ___ = 8 − 7, with the blank before the equals sign. The fact is unchanged, 8 − 7 = 1. It checks that a pupil reads the sign as 'is the same as' and not as 'write the answer here'. Grade 1 standards name this idea: Common Core 1.OA.7 and Texas 1.5(E).
Side by side, 30 facts acrossThe opening sheet's facts written in a line, 7 − 6 = 1, in 3 columns of 10. Stacked is the form column subtraction uses, and side by side is the form equations and word problems use. Print both so that neither one looks new on the day it matters.
Past one digit: from 10 and the teens, up to 18 − 9 5
All 100 basic facts, 0 − 0 to 18 − 9Every subtraction fact that undoes a one-digit sum, each printed once: the 55 one-digit facts and the 45 that start from 10 to 18, as far as 17 − 9 = 8 and 18 − 9. Texas asks grade 2 pupils to recall basic facts within 20 with automaticity (2.4(A)). This page is the whole list.
Facts from 2 to 10, no zeros, 30 stackedThirty stacked facts where the start number runs from 2 to 10, so 10 − 6 = 4 can appear beside the one-digit facts. 0 is never taken away and no number is subtracted from itself, so every answer is at least 1. The 45 facts that fit are dealt like a shuffled deck, so none repeats on a page of 30.
Facts from 2 to 10, no zeros, 100 stackedThe same rules on a page of 100 for a longer run: start numbers from 2 to 10, no zeros, every answer at least 1, as in 10 − 8 = 2. The 45 facts that fit are dealt like a deck, all of them, then all of them again in a new order, then 10 more, because 45 + 45 + 10 = 100.
Take away from 10, 10 − 1 to 10 − 9The 9 facts that start from 10 and take away a one-digit number, each printed twice at the opening count. 10 − 3 = 7 is the number bond 3 and 7 seen from the other side, so a pupil who knows the pairs that make 10 already knows this page. These facts are also the middle step of subtracting through ten.
Teen facts that cross ten, 11 − 2 to 18 − 9The 36 facts that undo a one-digit sum above 10: the top number runs from 11 to 18, and the number taken away and the answer are both one digit, as in 14 − 6 = 8. Thirty are printed with no repeats. Every one crosses ten, so this is the hard end of the basic facts.
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 (by counting back and by adding the answer to the number taken away), and every count of facts on this page (55, 45, 36, 26, 19, 15, 10, 9, 8 and 100) was counted by listing the facts by script on the same day. Standards 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.4 (subtraction as an unknown-addend problem), 1.OA.5 (relate counting to addition and subtraction), 1.OA.6 (add and subtract within 20 with fluency within 10, decomposing a number leading to a ten, and using the relationship between addition and subtraction), 1.OA.7 (the meaning of the equal sign, true or false equations), 1.OA.8 (the unknown whole number in an equation) and 2.OA.2 (fluently add and subtract within 20; know from memory all sums of two one-digit numbers); and against the Texas Essential Knowledge and Skills for Mathematics, 19 TAC 111.3 Grade 1 and 111.4 Grade 2 (https://tea.texas.gov/sites/default/files/ch111a.pdf): 1.3(D), 1.5(E), 1.5(F) and 2.4(A). Checked 2026-09-19 against Wikipedia (https://en.wikipedia.org/wiki/Subtraction): subtracting 0 does not change a number, the difference of two natural numbers is a natural number only when the first is at least as large as the second, and counting up is a named method of subtraction.
