Printable addition flash cards from your own material

- Spaced repetition brings back the facts you miss
- PDF export is included on Plus for printing

Built from your material
Upload a worksheet, answer key, slides or a photo of a page, and the cards match the facts you are actually working on.
Spaced repetition
Cards you miss come back sooner, so the facts you struggle with get more practice without extra planning.
PDF export on Plus
Plus exports your set as a PDF so you can print it at home or at a copy shop.
How it works
Upload your pages
Add a PDF, DOCX, slides, plain text or a photo of the page. Text recognition reads the photo.
Review the cards
Check the generated addition problems and answers, and remove any that do not fit your lesson.
Export and print
On Plus, export the set as a PDF, print it, and cut out the cards.
Printing needs a paid plan. The Free plan lets you study in the browser with 3 generations a month, while Plus at $39/year or $7.99/month adds unlimited generations and PDF export. Students with a school email get 40% off, and no credit card is needed to start.
Upload the page you already use, review the cards, then export the set when you are ready. Pro adds a stronger AI model and bulk upload if you are making sets for many students at once.

Frequently asked questions
How many addition facts should a flash card set cover?
Most early learners do well starting with one fact family or sums to 10 before moving to sums to 20. Add a few review cards from earlier units so older facts stay fresh.
What is the best way to study addition flash cards?
Say each answer aloud before flipping the card, then sort cards into known and not yet known piles. Repeat the not yet known pile first until it gets smaller.
Can I print my flash cards on the Free plan?
Printing needs a PDF export, which is included on Plus. The Free plan lets you study the cards in your browser with 3 generations 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% off Plus.
