Turn your own number lessons into black and white flashcards
Upload a worksheet, slides, notes or a photo of a page. DeckOwl writes flashcards from your material, with spaced repetition to help the numbers stick.
Custom number flashcards instead of a generic printout
A generic sheet of black and white number flashcards is handy for a quick drill, but it rarely matches the numbers your class is actually working on. If your teacher sent a worksheet on place value, word problems or Roman numerals, upload that file instead and get flashcards built from it.
- Works from the worksheet or notes your teacher already gave you
- Covers numerals, number words, place value and times tables
- Spaced repetition brings back the cards you keep missing
- Free plan includes 3 generations a month to try it out
Built from your material
Upload a PDF, DOCX, PPTX, text notes or a photo of a worksheet and get cards that match what your class is covering.
Spaced repetition
Cards you miss come back more often, so number facts, place value and word forms stay in memory.
Print or study
Study in the browser on the free plan. Plus adds PDF and DOCX export, so you can print a black and white set.
How it works
Upload your file
Add the worksheet, notes or page photo that has the numbers you need to practice.
Generate flashcards
DeckOwl creates question-and-answer cards from the content, including numerals, number words and place value.
Study or print
Work through the deck with spaced repetition, or export a PDF on Plus to print it in black and white.
DeckOwl reads PDFs, DOCX, PPTX, plain-text notes and photos of pages, then writes flashcards with the question on the front and the answer on the back. Spaced repetition schedules the cards you miss more often, so you do not have to re-sort a pile by hand. PDF and DOCX export come with Plus, so you can print a set if you still want paper.

Frequently asked questions
How many number flashcards should I make for one practice session?
Start with around 15 to 20 cards so a session stays short enough to finish. Add more once you consistently get most answers right on the first try.
How do I help a child learn number words and numerals together?
Put the word on one side and the digits on the other, then quiz in both directions. Switching directions keeps the learner reading the word and writing the numeral.
Can I print my flashcards in black and white?
Yes, PDF export is part of the Plus plan at $39/year or $7.99/month, and the file can be printed in black and white. The free plan lets you study in the browser but does not include exports.
Do I need a credit card to try DeckOwl?
No, you can start on the free plan without a credit card. It includes 3 generations per month and browser study, and students get 40% off with a school email.
