Turn your own number sheets into printable 1-20 flashcards with AI
Ready-made downloads rarely match how your child or class counts. Upload a worksheet, photo or notes and get 1-20 flashcards built from that exact material, with spaced repetition. Studying in the browser is free, and PDF export is included on Plus.
Why a custom set works better than a generic download
A child learning to count past ten needs cards that use the same number words, digits and dot patterns as their classroom, and a generic download rarely matches. A printable numbers 1-20 flashcards set made from your own worksheet keeps the layout and vocabulary your learner already sees.
- Use your own worksheet so the number words match your classroom
- Mix digits, number words and dot counts on the same set
- Review missed cards more often through spaced repetition
- Print a PDF or export to Anki with a Plus plan
Built from your material
Upload a PDF, slide deck, typed notes or a photo of a worksheet. Text recognition reads the numbers and words on the page.
Spaced repetition
Cards you miss come back sooner, so 1-20 facts stick without drilling the same cards every day.
Export when you need paper
Plus exports your set as a PDF, DOCX, Anki deck or CSV so you can print it or load it into another app.
How it works
Upload your sheet
Add the PDF, photo or notes that cover the numbers you are working on.
Review the cards
DeckOwl drafts question and answer cards. Edit any that do not match how your teacher writes the numbers.
Study or export
Practice in your browser for free, or export a PDF on Plus when you want something to print.
Start with the numbers that give trouble, such as 13 versus 30 or 'fourteen' versus 'forty'. Mixing number words and digits on the same card helps children connect the two forms.
Generate a new set whenever the lesson changes, then study the cards in your browser for free. Upgrade to Plus when you want a PDF to print for home or the classroom.

Frequently asked questions
How many flashcards should I make for numbers 1 to 20?
Twenty cards, one per number, is a solid starting set. Many learners add a second set that pairs each digit with its number word, such as 14 and fourteen.
What should be on the front and back of a number flashcard?
Put the digit or a dot pattern on the front and the number word on the back, or the reverse once the first direction is easy. Keep one fact per card.
Can I print my flashcards for free?
The free plan lets you study in the browser, but PDF export is a Plus feature. Plus also includes DOCX, Anki and CSV export.
Do I need a credit card to start?
No. You can create a set and study it free without a credit card. Students with a school email get 40% off Plus.
