Turn a worksheet into addition and subtraction flashcards to 10
Teachers and parents often already have the problems they need on a worksheet or in a photocopied packet. Upload that material and DeckOwl builds cards you can review in the browser, with spaced repetition bringing back the facts a child is still missing.
Why build the cards from your own material
A worksheet of sums already holds most of what a child needs for practice, so you can skip the printing and turn it into addition and subtraction flashcards to 10 directly. Upload a photo, PDF, or typed notes and DeckOwl reads the problems and turns them into cards you can study in the browser.
- Cards that match the exact problems on a worksheet, not generic sets
- Fact families shown together so subtraction connects to addition
- Review scheduled by spaced repetition so missed facts return sooner
- Print or move the deck to Anki with a paid plan
Reads your photos and PDFs
Snap a photo of a worksheet or upload a PDF, slides, or typed notes. Photos are read with text recognition, so the problems come through as cards.
Spaced repetition
Cards you miss return sooner and cards you know come back less often, so the facts that need practice get the most attention.
Export when you need paper
Plus adds PDF, DOCX, Anki, and CSV export, so you can print a set or load it into Anki on a paid plan.
How it works
Add your material
Upload the worksheet photo, PDF, or notes that contain the addition and subtraction problems.
Review the cards
Check the generated fronts and backs and remove anything that does not match the page.
Study a little each day
Work through the deck in the browser. Spaced repetition schedules the missed facts for another look.
Addition and subtraction within 10 are best learned as fact families, where 3, 4, and 7 link to 3 plus 4, 4 plus 3, 7 minus 3, and 7 minus 4. Cards that show the related facts together help a child see that subtraction undoes addition, and spaced repetition keeps the weaker facts coming back until they are automatic.

Frequently asked questions
How should I use addition and subtraction flashcards to 10 with a young child?
Keep sessions short and frequent, and mix addition and subtraction in the same review so the child learns which operation to use. Start with the facts the child already knows and add a few new ones at a time.
What is a fact family and why does it help?
A fact family links three numbers, such as 2, 5, and 7, into two addition facts and two subtraction facts. Practicing them together helps children see that subtraction reverses addition.
Can I export the cards to print or to Anki?
Exports are a paid feature. Plus includes PDF, DOCX, Anki, and CSV export, so you can print cards or load them into Anki. The free plan lets you study in the browser without exports.
Is there a free plan, and do I need a credit card?
Yes, the free plan includes 3 generations per month and browser study. No credit card is needed to start, and students get 40% off with a school email.
