Why generate your own addition flashcards

Printable addition flashcards are handy for drilling facts, but a generic sheet rarely matches the problem types your teacher assigned or the strategies your class is learning.

Cards come from your worksheet or notes, not a generic list.
Photos of pages are read with text recognition.
Spaced repetition schedules review based on what you miss.
PDF export is available on Plus; the free plan studies in the browser.

What is 27 + 46?73. Add the ones first: 7 + 6 = 13, write 3 and carry 1. Then add the tens: 2 + 4 + 1 = 7.

What is the associative property of addition?Regrouping addends does not change the sum, so (2 + 3) + 4 = 2 + (3 + 4) = 9.

Generate the full set

Starts from your PDF

Upload a worksheet, textbook scan, or slide deck in PDF, DOCX, PPTX, or as a photo. Text recognition reads the page so the cards match what your class is actually practicing.

Spaced repetition built in

Cards you miss come back sooner and cards you know fade to longer gaps, so addition facts move from careful counting to fast recall.

Export when you need paper

Plus users can export flashcards as PDF, plus Anki and CSV files. Free users study in the browser with three generations a month.

How it works

Upload your material

Add a PDF worksheet, notes, or photos of the page. No credit card is needed to start.

Review the cards

Check the generated question and answer pairs and remove any that do not fit your lesson.

Study or export

Practice in the browser with spaced repetition, or export a printable PDF on a Plus plan.

Uploading your own worksheet or notes lets DeckOwl write cards that follow that material, including carrying, place value, and word problems, so practice lines up with homework and tests.

Spaced repetition then schedules review over days, which helps more than one long session of the same sheet. Plus users can export the set as PDF for offline practice.

Frequently asked questions

How many addition flashcards should I make for a week of practice?

Start with 20 to 30 cards from one lesson, then add more as you master them. Short daily sessions of about 10 minutes usually work better than one long session.

What should a good addition flashcard look like?

Put one problem or property on the front, such as 27 + 46 or the commutative property, and the answer with a brief step on the back. Keep each card focused on a single fact.

Can I print my flashcards as a PDF?

Yes, PDF export is included in the Plus plan at $99.90/year or $9.99/month. The free plan lets you study the cards in your browser with three generations per month.

Can I use a photo of my worksheet instead of a PDF?

Yes, photos of pages are read with text recognition, so you can upload a picture of a worksheet along with PDFs, DOCX, PPTX, or notes.
