Turn any number list from 1 to 50 into printable flashcards
Upload a worksheet, slide deck or photo of a number chart and get flashcards you can review with spaced repetition. Printing and PDF export are part of Plus; the free plan includes 3 generations a month and browser study.
Why a custom set beats a generic printout
Many parents and teachers want printable number flashcards for 1 to 50, but a generic sheet rarely matches the number words, formats or sequences the learner is working on.
- Choose how many numbers to include, such as only 1 to 20 for a first pass.
- Add number words on the back so learners practice spelling as well as digits.
- Review in the browser on the free plan before deciding whether to print.
- Export a PDF with Plus when you are ready to print a classroom or home set.
Built from your own page
Upload the exact worksheet or chart your child or class uses, and the cards match the number words, layout and examples on that page.
Spaced repetition
Numbers you miss come back sooner, so the hard ones such as 13 and 30 get extra practice without you sorting the deck by hand.
Print or export on Plus
Plus exports your set as a PDF for printing, plus DOCX, Anki and CSV files, with unlimited generations.
How it works
Upload your material
Add a PDF, DOCX, PPTX, text notes or a photo of a number chart. Photos are read with text recognition.
Generate the cards
DeckOwl creates flashcards covering the numbers in your material, with the number word on the back where it applies.
Study or print
Review in the browser on the free plan, or export a PDF with Plus to print for practice at home or in class.
A child who can count to 50 may still stumble on teens like 16 and 18 or confuse 13 with 30. A set built from the numbers on their own worksheet targets exactly those gaps, and spaced repetition brings missed cards back sooner.

Frequently asked questions
How many number flashcards should a child practice at once?
Start with 10 to 15 cards and add more once the learner answers most of them correctly. Spaced repetition shows missed numbers again sooner, so the set adjusts on its own.
Which numbers from 1 to 50 are usually hardest for early learners?
Teens such as 13 and 15 are often mixed up with the tens such as 30 and 50 because the endings sound alike. Reversed pairs like 12 and 21 also cause errors, so include both digits and words on the card.
Can I print my flashcards?
Yes, PDF export is included with Plus, which costs $39 a year or $7.99 a month. The free plan gives 3 generations a month and study in the browser, but it does not include exports.
Do I need a credit card to try it?
No, you can start on the free plan without a credit card. Students with a school email get 40% off Plus.
