Turn your shape lessons into flashcards with AI
Printable shape sheets can work for a quick look, but they rarely match what your class is covering. DeckOwl builds shape flashcards from your own PDFs, slides, notes or photos of a worksheet.
Why generate shape flashcards instead of printing them
Most people searching for shape flashcards want something ready to hand to a child or drop into a lesson, and printed sets do cover the basics. The trouble is that a generic sheet rarely matches the shapes your class is working on this week or the way your teacher names them.
- Front and back pairs for shape names, sides, angles and examples
- Cards built from your own slides, PDFs, notes or photos of a worksheet
- Spaced repetition so the shapes you miss come back more often
- Browser study on the free plan, with PDF export included in Plus
Cards from your material
Upload the worksheet, slide deck or page photo you already use, and the AI writes question and answer cards from it.
Spaced repetition
Cards come back on a schedule, so tricky shapes like rhombus and trapezoid appear more often until they stick.
Study anywhere
Study in your browser on the free plan. Plus adds PDF and Anki export so you can print or load the cards.
How it works
Upload your material
Add a PDF, slides, typed notes or a photo of the page. Text recognition reads photos.
Review the generated cards
Check the shape names, side counts and properties, and edit anything that does not match your lesson.
Study with spaced repetition
Open the set in your browser and review daily. Cards you miss return sooner.
DeckOwl works the other way around. Upload the worksheet, slide deck or a photo of the page, and the AI writes cards from that exact material, so each front asks about the term or property you need. Cards then return on a spaced schedule, which helps names and properties stick.

Frequently asked questions
How many shape flashcards should I make for a first grade geometry unit?
Keep each set to the shapes covered that week, so students can review it in a few minutes a day. Adding more shapes once the earlier ones are secure works better than one large deck.
What should a shape flashcard show on the front and back?
Put a shape name or a property question on the front, such as how many sides a triangle has. The back should give the answer in a short phrase, ideally with a real-world example.
Can I print my DeckOwl shape flashcards?
The free plan lets you study in the browser but does not include exports. PDF export is part of the Plus plan at $39 per year or $7.99 per month, which lets you print your cards.
Is there a free plan to try it first?
Yes. The free plan includes 3 generations per month and no credit card is needed to start. Students can get 40% off Plus with a school email.
