Get addition flashcards with answers from your own practice sheets
Upload a worksheet, a photo of a page, or slides, and DeckOwl writes question-and-answer cards you can review with spaced repetition.
Why generated addition cards beat a generic printable
Printable addition sheets are everywhere, but addition flashcards with answers work best when they match the exact facts you are practicing, and a generic download rarely does.
- Cards come from your own worksheets, so the problems match your course.
- Every card shows the correct answer on the back for quick self-checks.
- Missed facts return more often through spaced repetition.
- Free plan includes browser study; PDF, DOCX, Anki and CSV export are on paid plans.
Built from your material
Upload PDFs, DOCX or PPTX files, plain notes, or photos of worksheets. The cards match the problems your class is actually using.
Answers on every card
Each flashcard has the question on the front and the correct answer on the back, so you can check yourself right away.
Spaced repetition
Cards you miss come back more often, while facts you know are shown less, so basic sums stick over time.
How it works
Upload your worksheet or notes
Add a PDF, document, slide deck, or a photo of a page. Text recognition reads the problems and answers.
Generate your flashcards
DeckOwl creates cards with answers from your material. Free accounts get 3 generations per month.
Study with spaced repetition
Review in short sessions in the browser. The cards you miss return sooner until they become automatic.
DeckOwl reads your own material, whether that is a worksheet saved as a PDF, a page from a workbook photographed with your phone, or notes typed into a document. Each question becomes a card with its answer on the back, so the set reflects what your class is covering.
Once the cards exist, spaced repetition schedules the ones you miss more often, so the basic facts stick without rereading the whole sheet.
