Turn your number concept notes into flashcards with AI
Skip the generic printable set. Upload a worksheet, slides, or a photo of a page, and DeckOwl builds flashcards that match what your class actually covered.
Why build your own number concept deck
Printed number concept flashcards are common in early math classrooms, but a generic deck rarely matches the exact counting, place value, or ordering skills your lesson covered. Generating cards from your own material keeps practice tied to the worksheet in front of you.
- Pull cards from a counting or place value worksheet in one upload.
- Keep each card to one idea so a wrong answer points to one gap.
- Study in the browser on the free plan, or export to Anki with Plus.
- Students with a school email get 40% off Plus.
Upload what you already have
Send PDFs, DOCX or PPTX files, plain notes, or photos of pages. Photos are read with text recognition.
Spaced repetition
Cards come back at the intervals where you are most likely to forget them, so number facts stick.
Quizzes and mind maps
Turn the same material into multiple choice, true/false, or short answer quizzes with explanations.
How it works
Upload your material
Add a counting worksheet, a place value lesson, or a photo of a page from class.
Generate your cards
DeckOwl creates flashcards from the text it finds, ready to review in the browser.
Study on a schedule
Review each card as it comes due. PDF and Anki exports are included with Plus.
Number concept builds on a few core ideas: cardinality (how many items are in a set), ordinality (position in a sequence), and place value (a digit's worth depends on where it sits). Cards that ask about one idea at a time are easier to review in short sessions and reveal gaps quickly.

Frequently asked questions
How many flashcards should I make for early number concepts?
Start with 15 to 25 cards from one lesson so each review session stays short. Add more as new skills like place value or skip counting come up in class.
What should a number concept card ask?
Good cards target one idea, such as whether 6 is greater or less than 9, or which digit holds the tens value in 52. Avoid cards that mix several skills at once.
Can I print the flashcards DeckOwl makes?
PDF export is part of Plus, which costs $39 per year or $7.99 per month. The free plan lets you study in the browser but does not include exports.
Do I need a credit card to try it?
No. You can start on the free plan with 3 generations per month and no credit card.
