How to get printable number flashcards that match your lessons
Ready-made printable sheets are easy to find, but they rarely match the number facts your teacher or textbook uses. Printable number flashcards made from your own material line up with the exact skills in front of you, whether that is place value, multiplication or percent problems.
- Cards come from your own worksheet, textbook or notes, not a generic list.
- Spaced repetition brings back the number facts you keep missing.
- Photos of printed pages are read with text recognition, so you do not need to retype anything.
- PDF export for printing is available on Plus; the free plan is for studying in the browser.
Built from your material
Upload a PDF, DOCX, PPTX, plain text or a photo of a page, and the flashcards come from what your class is actually working on.
Spaced repetition
Cards you miss come back sooner and cards you know come back later, so practice time goes to the facts you still need.
Export on Plus
Plus includes PDF and DOCX export for printing, plus Anki and CSV export for other apps.
How it works
Upload your source
Add the PDF, slides, notes or image that contains the numbers you want to practice.
Generate the cards
DeckOwl creates flashcards from the material. Review them and remove anything you do not need.
Study or print
Study in the browser on the free plan, or export a PDF to print once you are on Plus.
The free plan includes 3 generations per month and lets you study in the browser, so you can test the cards before deciding anything. Printing needs an export, and PDF export is included with Plus, which costs $99.90 per year or $9.99 per month.
Students can get 40% off with a school email, and no credit card is needed to start. Spaced repetition works the same whether you study on screen or from a printed set, so the schedule matters more than the format.

Frequently asked questions
How often should I review number flashcards?
Short daily sessions work better than one long session each week. Spaced repetition helps by scheduling the cards you find hard more often.
What is the best way to practice number facts with flashcards?
Say the answer out loud before you flip the card, and write down any fact you miss so you can focus on it. Mixing easy and hard cards in one session keeps practice useful.
Can I download these flashcards as a free PDF?
The free plan does not include exports, so you can study in the browser but cannot download a PDF. PDF export is available on Plus at $99.90 per year or $9.99 per month.
Do I need a credit card to start?
No. You can start on the free plan without a credit card, and students with a school email get 40% off a paid plan.
