Turn your addition worksheets into flashcards with answers
Printable sets work for a quick drill, but a deck built from your own worksheet keeps the same problems you practice in class.
Custom addition flash cards from your own material
Printable sheets of addition flash cards with answers on back are easy to find, but they rarely match the problems your teacher actually assigned.
- Put one problem on each front, such as 7 + 8
- Write only the sum on the back so recall is quick
- Shuffle the deck instead of drilling one row in order
- Spend more time on missed cards than on the ones you already know
Reads your worksheets
Upload a PDF, DOCX, PPTX, plain text notes, or a photo of a page, and the text is pulled out for you.
Answers on the back
Each card puts the problem on the front and the correct sum on the back, so you can check yourself right away.
Study in the browser
The free plan includes three generations a month and browser study. Plus adds exports and spaced repetition.
How it works
Upload your material
Add a PDF, slide deck, notes, or a photo of a page that has the addition problems on it.
Generate the cards
DeckOwl builds flashcards from the problems, with the answer on the back of each card.
Flip and review
Study the cards in your browser and spend extra time on the ones you miss.
A deck made from your own worksheet or notes keeps the same numbers and formats you practice in class. Upload the file, and each problem becomes a front with its answer on the back.
Mix the cards up rather than working through one row in order. Shuffling helps you recall each sum on its own, which is the skill a quiz tests.

Frequently asked questions
How do I make addition flash cards with answers on the back by hand?
Write one problem on the front of each card, such as 9 + 5, and the sum on the back, such as 14. Keep each card to a single fact so you can check yourself quickly.
Which addition facts should kids learn first?
Most early math programs start with doubles like 4 + 4 and facts that make 10, such as 6 + 4. Once those are automatic, practice sums to 20 in mixed order.
Can I export my addition flashcards?
The free plan lets you study in the browser but does not include exports. PDF, DOCX, Anki, and CSV export are part of Plus, which costs $39/year or $7.99/month.
