Reads your pages

Upload a PDF, slide deck, notes file or a photo of a worksheet, and text recognition pulls out the numbers and prompts.

Spaced repetition

Cards you miss come back more often, and the ones that are already solid appear less, so practice time goes further.

Study anywhere

Practice in the browser on the free plan, or export to PDF, DOCX, Anki or CSV on Plus.

How it works

Upload your material

Add a worksheet, a page from a counting book, or a photo taken with your phone.

Generate the cards

DeckOwl creates flashcards from the numbers and patterns on the page, with no credit card needed to start.

Review in short sessions

Study a few minutes a day and let spaced repetition bring back the numbers that still need work.

Spaced repetition brings back the cards a child misses more often and spaces out the ones they already know, so practice time goes to what is still hard. Parents and teachers can look over the generated cards together before studying starts, and edit anything that does not match the lesson.

Frequently asked questions

How do I help a child learn to count to 100?

Practice counting by ones, then by tens, and point out the pattern in each row of a hundred chart. Short daily sessions with the same tricky pairs, such as 38 and 83, tend to work better than one long session.

Which numbers are hardest to remember when learning to 100?

Many children mix up the teen numbers like 13 and 30, and the pairs where the tens and ones digits swap. Cards that show both forms side by side help children notice the difference.
