Turn your own addition worksheets into flash cards with AI
Printed addition sheets only cover the problems someone else picked. Upload your own practice material and get flashcards that match what your student actually needs to drill.
Why custom addition practice beats a generic printable
Many parents and teachers search for addition flash cards because quick drills build speed, but a generic printable only covers the problems its author chose. A child who is solid on sums to 10 and stuck on carrying across the tens place needs cards built around that gap.
- Works from PDFs, slides, notes and photos of worksheets
- Spaced repetition schedules missed addition facts sooner
- Free plan includes browser study with 3 generations per month
- Plus adds unlimited generations and exports to PDF, DOCX, Anki and CSV
Built from your material
Upload a PDF, slide deck, typed notes or a photo of a worksheet, and the flashcards come from those exact problems.
Spaced repetition
Cards you miss come back sooner and mastered ones appear less often, so practice time goes to the facts that need it.
Study in the browser
The free plan lets you study right away in the browser. Exports to PDF, DOCX, Anki and CSV are available on paid plans.
How it works
Add your practice set
Upload a worksheet, a photo of a page, or typed addition problems. Text is read from images automatically.
Generate the cards
DeckOwl builds question-and-answer flashcards from the material you provided, so each card matches a problem your student has seen.
Play and review
Work through the deck in the browser, mark what was hard, and let spaced repetition schedule the next round.
DeckOwl reads your own material and turns it into flashcards, so the game reflects your classroom sheet, homework or workbook. Spaced repetition then brings back the problems that were missed and reduces the ones that are already automatic.
Start with the free plan, which includes 3 generations per month and browser study. If you want to print or move the cards into another app, PDF, DOCX, Anki and CSV exports are included with Plus.

Frequently asked questions
How many addition flashcards should a child practice in one session?
Most young learners do well with a short set of about 10 to 20 cards per session, repeated across several days. Keep sessions brief and stop before accuracy drops.
Which addition facts should be memorized first?
Start with facts up to 10, then doubles like 6 plus 6, then make-ten pairs like 8 plus 2. Once those are automatic, move to two-digit addition with regrouping.
Can I print the flashcards?
Printing and file exports such as PDF are part of the Plus plan. The free plan lets you study the cards in the browser.
Do I need a credit card to try DeckOwl?
No. You can start on the free plan without a credit card. Students with a school email get 40% off paid plans.
