Why generate arithmetic flashcards from your own work
Practice sets and printed worksheets rarely match the problems your class actually covers, so arithmetic flashcards online are most useful when they come from your own material. Upload a photo of a worksheet, a PDF of lecture slides or typed notes, and DeckOwl turns the key facts and worked examples into cards you can study in your browser.
- Fraction, decimal and percent conversions on one card each
- Order of operations problems with the reasoning on the back
- Times tables and division facts pulled from a photo of your worksheet
- Worked examples from your textbook chapter instead of a generic list
Works from your files
Upload PDFs, DOCX or PPTX files, plain notes, or photos of pages that are read with text recognition.
Spaced repetition built in
Cards you miss come back sooner, so practice time goes to the facts that need it most.
Quizzes and mind maps too
Turn the same material into multiple choice, true/false or short answer quizzes with explanations.
How it works
Upload your material
Add a worksheet photo, lecture slides, a PDF or typed notes.
Generate your cards
DeckOwl creates flashcards from the content you provided.
Study in the browser
Review with spaced repetition and return to the cards you keep missing.
Spaced repetition then shows you the cards you miss more often and spaces out the ones you already know. That helps multiplication facts, fraction conversions and order of operations stick over weeks rather than the night before a test. Free accounts get 3 generations a month with browser study, and Plus adds unlimited generations plus PDF, DOCX, Anki and CSV export.

Frequently asked questions
How many flashcards should I make for a unit on fractions?
Most units work well with 20 to 40 cards, with one fact or one problem type per card. Start with the procedures your test will ask for and add harder mixed problems once those feel easy.
What is the best way to study arithmetic facts I keep forgetting?
Review the cards you miss daily in short sessions of 10 to 15 minutes, and say the reasoning aloud before flipping each card. Spacing practice across several days works better than one long cram session.
Can I study the flashcards on my phone without downloading an app?
Yes. Free accounts study in the browser, so any device with a web connection can be used.
Can I export my arithmetic flashcards to Anki?
Export to Anki, CSV, PDF and DOCX is part of the Plus plan at $39 per year or $7.99 per month. The free plan includes 3 generations per month and browser study without exports.
