Turn your addition worksheets into printable math flashcards
Upload a worksheet, photo, PDF or slide deck and get addition flashcards with spaced repetition. Printing works through PDF export on the Plus plan.
Why generate your own printable addition sets
Addition facts stick when a child drills them in short, repeated sessions, and a ready-made sheet rarely matches the sums in the current unit. Generating printable math addition flashcards from the worksheet or notes your child already has keeps practice aligned with what they are learning.
- Use the exact problems from a worksheet or textbook page
- Start with one fact family, such as sums to 10, before adding more
- Print a PDF on Plus for paper drills or cut-out cards
- Study on any device in the browser on the free plan
Built from your own worksheets
Upload a worksheet, a photo of a page or a typed list of facts, and the flashcards match the problems your student actually practices.
Spaced repetition
Cards that are missed come back sooner, and mastered facts are shown less often, so practice time goes to the sums that need it.
Print-ready PDF export
Export your set as a PDF on Plus, then print it for paper drills or cut-out cards. The free plan keeps cards in the browser.
How it works
Upload your material
Add a PDF, DOCX, slide deck, plain text notes or a photo of a worksheet.
Review the generated cards
Check the addition facts and answers, then edit any card that needs a different problem.
Study or print
Practice in the browser with spaced repetition, or export a PDF on Plus to print.
A custom set also grows with the child. When a family or teacher adds new problems, such as sums to 20 after sums to 10, the flashcards can be regenerated from the new page instead of hunting for another printout.

Frequently asked questions
How many addition facts should one flashcard set cover?
Start with one range, such as sums to 10, and aim for about 20 to 30 cards. Add the next range only after most of the first set is answered quickly and correctly.
What is the best way to practice addition flashcards with a young child?
Short daily sessions of five to ten minutes work better than one long session. Say the answer aloud, and review missed cards first until they are recalled without counting on fingers.
Can I print the flashcards?
Yes, printing uses a PDF export, which is included in the Plus plan at $99.90/year or $9.99/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.
