Make addition flashcards from your own lesson notes
DeckOwl does not make videos. It turns the PDFs, slides, notes or photos you already have from a video lesson into text flashcards you can review with spaced repetition.
How addition flashcards fit with video lessons
Many students search for addition flashcards with video because a lesson shows the method once, but memory needs repeated practice afterward. Pairing a video with flashcards from its own notes works well for that.
- Cards come from the lesson material you provide, not a generic list.
- Photos of worksheets are read with text recognition.
- Spaced repetition focuses review on the addition facts you miss.
- Free plan includes 3 generations per month and browser study.
Built from your material
Upload a worksheet, lesson slides or notes and get flashcards drawn from that exact content.
Spaced repetition
Cards you miss come back sooner, so addition facts stick over several study sessions.
Photos work too
Snap a page of worksheet problems and the text is read so you can turn it into cards.
How it works
Add your material
Upload a PDF, DOCX, PPTX, plain text notes or a photo of a page.
Generate flashcards
Get question-and-answer cards covering the addition facts and rules in that material.
Study in the browser
Review on any device, and the cards repeat on a spaced schedule.
Write down the steps the teacher used, or upload the slides or worksheet, and DeckOwl builds cards that ask for each fact, rule and worked answer. The cards are text, not video, so you can keep the lesson open in another tab while you check your answers.
Review in short sessions. Spaced repetition brings back the cards you keep missing, such as carrying in column addition, so you spend less time on facts you already know.

Frequently asked questions
How many addition flashcards should I make for one lesson?
Most single lessons work well with 15 to 30 cards, covering each fact type, the vocabulary such as addend and sum, and one worked example per method. Add more cards when you find you keep missing the same type.
What should an addition flashcard include besides the answer?
Include the problem, the answer and a short note on the method, such as regrouping or the commutative property. Seeing the reason helps the fact stick better than a bare number.
Can I export addition flashcards to Anki or CSV?
Exports are part of the paid Plus plan, which includes PDF, DOCX, Anki and CSV export. The free plan lets you study in the browser without exporting.
Does DeckOwl cost anything to start?
The free plan gives you 3 generations per month and no credit card is needed. Students can get 40% off Plus with a school email.
