Turn your addition practice sheet into printable flash cards
Upload a worksheet, notes or a photo of a page and get addition flashcards from 0 to 20. The free plan studies in the browser, and PDF export is included with Plus.
Why a custom set beats a generic download
Most printable addition flash cards 0 to 20 are generic, so they rarely match the facts a child or class is working on this week. A set built from the actual worksheet keeps the same number formats and problem layout the learner already sees.
- Start from a worksheet or notes you already have, so the numbers match what is being taught.
- Use doubles like 6 + 6 and make-ten facts like 8 + 5 as separate cards to build quick recall.
- Keep each set focused on one range, such as sums to 10 first, then sums to 20.
- Print the PDF for offline practice, or study in the browser on the free plan.
Built from your material
Upload a PDF, slide deck, notes file or photo of a worksheet. Each addition fact comes from the page you already use in class or at home.
Spaced repetition
Cards you miss come back sooner and cards you know come back later, so facts within 20 stick without daily drilling of the same ones.
Print or export
Plus exports your set as a PDF, along with DOCX, Anki and CSV files. The free plan keeps cards in the browser with no exports.
How it works
Upload your source
Add a PDF, DOCX, PPTX, text file or a clear photo of an addition worksheet covering 0 to 20.
Generate the cards
DeckOwl writes question and answer cards from the facts on the page. Free accounts get 3 generations per month.
Export a printable PDF
On Plus, export the set as a PDF and print it, or study the cards in the browser with spaced repetition.
Addition within 20 is practiced best in short, repeated sessions. Spaced repetition handles the scheduling, so the cards that cause trouble appear more often and the rest fade into quick review.
If you want a printable PDF, use Plus, which is $39 per year or $7.99 per month. You can start on the free plan with no credit card, then upgrade once you need to print.

Frequently asked questions
How do I practice addition facts from 0 to 20 effectively?
Practice short sessions several times a week rather than one long drill. Group facts by strategy, such as doubles, make-ten and near-doubles, so the patterns are easier to remember.
Why do addition facts up to 20 matter for later math?
Fluent recall of sums within 20 lets students focus on multi-step problems later instead of counting on their fingers. It also supports mental subtraction and place value work.
Can I print the flashcards as a PDF for free?
PDF export is a paid feature and is not included in the free plan. The free plan lets you study the cards in your browser, and Plus adds PDF export for $39 per year or $7.99 per month.
Do I need a credit card to try DeckOwl?
No. You can start on the free plan without a credit card, and students with a school email get 40 percent off a paid plan.
