Turn your own number worksheets into flashcards for 1 to 30
Printable sets are fine for a quick start, but a set built from the exact worksheet or list your child is working on is more useful. Upload it and get flashcards in minutes.
Why build your own set instead of downloading one
Many parents and teachers look for number flashcards to 30 when a child is first learning to count, read, and write numbers. A generic printable covers the basics, but children often mix up 13 and 30 or struggle with tens, so a set that matches the exact problems on their worksheet tends to stick better.
- Cover the exact numbers your child is practicing, such as 21 to 30 only, instead of a full page of every card.
- Include number words like twenty-five next to digits so reading and writing practice happen in the same deck.
- Review in short sessions of a few minutes, with cards repeated more often when they are missed.
- Students with a school email get 40% off Plus, and no credit card is needed to start.
Built from your material
Upload a worksheet, a photo of a page, or typed notes, and the flashcards come from what you actually need to practice.
Spaced repetition
Cards you miss come back more often, so numbers that are hard to recall get extra practice without you sorting the deck.
Works from a photo
Snap a picture of a printed number chart or class handout and the text is read with text recognition, so you do not retype anything.
How it works
Add your source
Upload a PDF, DOCX, PPTX, plain text, or a photo of the page with the numbers you want to cover.
Generate the cards
DeckOwl reads the material and writes flashcards with a question on the front and the answer on the back.
Study in the browser
Practice on any device with spaced repetition. Paid plans can export to PDF for printing or to Anki.
DeckOwl starts from your own material. Give it the page, slides, or notes you already have, and it writes question and answer cards that you can review in the browser on the free plan. Printing and other exports require the Plus plan.
