Make printable addition flashcards with answers from your own notes
Upload a worksheet, slides or a photo of a page and DeckOwl writes addition problems with answers on the back. Study free in the browser, or export a PDF on Plus.
Why a custom set beats a generic printable
Short daily drills work best when every answer is one flip away, and printable addition flashcards with answers on back are a simple way to get there. A ready-made sheet may not match the sums a child is practicing this week, though, so a set built from the actual worksheet or lesson is usually more useful.
- Upload the worksheet or lesson you are already using instead of searching for a generic sheet.
- Answers appear on the back of every card for quick self-checking.
- Start on the free plan with 3 generations per month and study in the browser.
- Plus includes PDF export so you can print a set, starting at $39/year or $7.99/month.
Built from your material
Upload a PDF, DOCX, PPTX, plain notes or a photo of a page. Cards match the problems your class or practice sheet actually uses.
Answers on the back
Each card puts the addition problem on the front and the correct sum on the back, so you can check answers in one flip.
Spaced repetition
Facts you miss come back more often, and the ones you know fade into longer gaps, so drill time goes to the hard sums.
How it works
Upload your sheet
Add a worksheet, slide deck, notes file or a photo of a page. Text is read from images with text recognition.
Generate the cards
DeckOwl writes flashcards with the problem on the front and the answer on the back.
Study or export
Practice in the browser on the free plan. Plus adds PDF export so you can print the set.
DeckOwl reads your files and writes one card per problem, with the sum on the back. Spaced repetition then brings back the facts that give trouble, so the set gets shorter as the child learns it.

Frequently asked questions
How many addition problems should a printable set include?
For early practice, 20 to 30 cards keeps a drill short enough to finish in a few minutes. Add two-digit problems once single-digit facts feel automatic.
What order should addition facts be learned in?
Many teachers start with doubles like 6 + 6, then move to make-ten facts like 9 + 4, where you bridge through 10. Practice each group until the answers come quickly before mixing them.
Can I print these flashcards?
Printing needs a PDF, and PDF export is included in Plus at $39/year or $7.99/month. The free plan lets you study the cards 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.
