Turn your own addition worksheet into basic addition flashcards
Printable sheets only cover the facts someone else picked. Upload a worksheet, slides or notes and get spaced repetition cards built around the sums you actually miss.
Why generate basic addition flashcards instead of printing them
Most ready-made sheets cover facts a child has already mastered, while the ones they miss are scattered across homework and quizzes. DeckOwl builds basic addition flashcards from whatever you already have: a photographed worksheet, a teacher's PDF, or typed notes listing the facts that need work.
- Photograph a worksheet and the problems are read for you
- Cards cover single-digit sums, missing addends and word problems
- Spaced repetition shows the sums you miss more often
- Quiz questions with explanations check that you understand the answer
Reads photos of worksheets
Snap a page and text recognition pulls out the problems, so you skip retyping.
Spaced repetition
Missed sums like 8 + 7 return sooner, while facts you already know appear less often.
Quizzes with explanations
Multiple choice, true/false and short answer questions show why each sum is right.
How it works
Upload your material
Add a PDF, DOCX, slides, typed notes or a photo of a worksheet.
Review the cards
DeckOwl drafts flashcards, and you keep the ones that match what you practice.
Study in short sessions
Use spaced repetition in the browser on the free plan, or export your cards on Plus.
Spaced repetition brings back the facts you are about to forget and shows the ones you know well less often. For addition, that means sums like 7 + 8 or 6 + 9 come back sooner than 2 + 2, so practice time goes where it is needed.
Free accounts get 3 generations per month and study in the browser. Exporting to PDF, DOCX, Anki or CSV is part of the Plus plan, so you can print a set for the car or import it into another app.

Frequently asked questions
How many addition facts should a flashcard set include?
Most children start with sums up to 10 and move to 20 once those are quick. A set of 20 to 40 cards per session is a manageable size for short daily practice.
What order should basic addition facts be learned in?
Start with doubles, adding 0 and 1, and making 10, since those patterns cover many facts. Practice harder sums like 7 + 8 once the easier ones feel automatic.
Can I print my flashcards?
Exporting to PDF or DOCX is part of the Plus plan, which costs $39 per year or $7.99 per month. The free plan lets you study the cards in the browser.
Does DeckOwl work with a photo of a worksheet?
Yes. Photos of pages are read with text recognition, so you can upload a picture of the worksheet instead of retyping the problems.
