Turn your number worksheets into online flashcards to practice
Upload a PDF, slide deck, notes or a photo of a worksheet and get flashcards with spaced repetition. DeckOwl does not include a ready-made game, but you can practice the same cards in your browser.
Practice number skills with cards made from your own material
Short daily drills help young learners recognize digits, count objects and remember number bonds. Many parents and teachers want online number flashcards they can reuse, and DeckOwl fits that need by building them from material you already have.
- Turn a worksheet of numerals and number words into flashcards
- Practice number bonds to 10 and simple addition facts
- Study in short browser sessions with spaced repetition
- Upgrade to Plus for exports to PDF, DOCX, Anki and CSV
Built from your material
Upload PDFs, DOCX or PPTX files, plain text notes, or photos of a page. Text recognition reads the numbers and terms so you do not have to retype them.
Spaced repetition
Cards you find hard come back more often, and cards you know are spaced further apart, so short daily sessions stick.
Study in the browser
Practice on any device with a browser. The free plan lets you study in the browser, and paid plans add exports to PDF, DOCX, Anki and CSV.
How it works
Upload your number material
Add a worksheet, a list of numbers and words, or a photo of a page from class.
Generate flashcards
DeckOwl turns the content into flashcards with a question on the front and the answer on the back.
Practice in short sessions
Study a few minutes a day in the browser and let spaced repetition decide which cards come back next.
DeckOwl does not ship a ready-made number game. It turns your own number lists, worksheets or photos of a page into flashcards you study in the browser, so the content matches what your learner is working on this week.
Keep each session to a few minutes and start with a small set of cards. Add new numbers once the current ones come quickly, and review the hard cards more often than the easy ones.
