Why a custom set beats a printed one

Printable number nine flashcards are easy to find, but a generic sheet rarely matches the worksheet or lesson in front of you. A set made from your own material focuses on the facts your class actually uses.

  • Turn a teacher's worksheet or slide deck into cards in one upload.
  • Check each card's answer before studying, and edit anything that looks wrong.
  • Review missed cards more often with spaced repetition.
  • Export to Anki, PDF or CSV on the Plus plan when you want to print or switch apps.
Example times table flashcards for the number 9
What is 9 × 7?63
What is 9 × 6?54, since 5 + 4 = 9
What is 9 × 9?81, since 8 + 1 = 9
Why do the digits of 81 add up to 9?Because 81 is a multiple of 9, and 8 + 1 = 9, which is the pattern that all multiples of 9 follow.
What is 9 × 12?108, because 9 × 10 = 90 and 9 × 2 = 18, and 90 + 18 = 108

Built from your material

Upload a PDF, DOCX, PPTX, text notes or a photo of a worksheet, and the flashcards come from that content.

Spaced repetition

Cards you miss come back sooner, and the ones you know fade into longer gaps, so review time goes where it helps.

Export when you need it

Plus users can export to PDF, DOCX, Anki or CSV, so the same set can be printed or moved into another app.

How it works

Upload your source

Add the page, slide deck or notes where number nine facts appear, or snap a photo of the page.

Generate the cards

DeckOwl reads the text and builds question-and-answer flashcards you can edit before studying.

Study on a schedule

Review in short sessions, and let spaced repetition bring back the cards you find hardest.

The number 9 has a useful pattern: the digits of every multiple of 9 add up to 9 or a multiple of 9. Practicing that rule alongside the basic facts gives you a quick way to check answers while you study.

Start with the twelve facts from 9 × 1 to 9 × 12, then add any that keep tripping you up. Short daily reviews usually work better than one long session before a test.
