Learn addition facts by heart with flashcards from your notes
Upload the sheets, slides or notes you already use and get flashcards for the sums you need to know cold.
Why memorized sums matter
Knowing sums cold, without counting on fingers, frees up attention for longer problems later. Most printable addition by heart flashcards are fixed sets that do not match the facts a child is actually missing, so the practice ends up in the wrong places. Generating cards from the worksheets and notes a student already has keeps practice focused on the exact sums that need work.
- Cards built from the sums on your own worksheets or class notes

Cards from your own material
Upload a PDF, a photo of a worksheet or typed notes and get question and answer cards for the sums you practice.
Spaced repetition
Cards you miss come back sooner, and the ones you know move to longer gaps between reviews.
Export when you need it
Plus exports to PDF, DOCX, Anki and CSV, so you can print a set if a teacher asks for one.
How it works
Upload your material
Add a PDF, slides, notes or a photo of a page. Text recognition reads images.
Check the cards
Review the generated question and answer pairs and edit anything unclear before you start.
Study on a schedule
Practice in short daily sessions and let spaced repetition bring back the sums you miss.
Start with the strategies that reduce how many facts must be memorized: doubles like 6 + 6, near doubles like 6 + 7, and make-ten facts like 8 + 5. Once those patterns are automatic, the remaining facts are far easier to lock in. Spaced repetition handles the rest by showing the hardest sums more often.

Frequently asked questions
What addition facts should I memorize first?
Most schools start with doubles and make-ten facts within 10, then move on to sums up to 20. Practicing the strategies first usually makes the rest of the facts easier to remember.
How often should I practice addition facts by heart?
Short daily sessions of a few minutes tend to work better than one long session each week. Spaced repetition helps by spacing reviews out so the sums you miss come back before you forget them.
Can I print my flashcards?
Printing is an export feature, so it is available on Plus at $99.90/year or $9.99/month. The free plan lets you study in the browser with three generations per month.
Do I need a credit card to start?
