Custom number flashcards, not a generic printable

Printable number flashcards for kids are handy for counting, digit recognition and simple addition, but a ready-made sheet rarely matches what your child is learning this week.

  • Counting to 20 and back, with the number word shown beside the digit.
  • Skip counting by 2s, 5s and 10s.
  • Comparing numbers with greater than and less than.
  • Simple addition and subtraction facts within 20.

Built from your own material

Upload a worksheet, slides, notes or a photo, and DeckOwl builds cards from the numbers and words on the page.

Spaced repetition

Cards your child misses come back sooner, so counting facts and number words stick without endless drilling.

Export when you need paper

Plus exports to PDF, DOCX, Anki and CSV, so you can print a set for the fridge or the car ride.

How it works

Upload a page

Add a PDF, a photo or a typed list of the numbers you want practiced.

Review the cards

Check the question and answer on each card and remove any that do not fit your child's level.

Study or export

Study in the browser on the free plan, or export to PDF on Plus.

Many parents who want a printable set are really after practice that fits the lesson in front of them. DeckOwl reads the worksheet or notes you already have and turns those exact numbers into cards, so the drills match the class.

Start with a free account and no credit card. The free plan gives you three generations a month to try it; PDF export requires Plus at $39 a year or $7.99 a month.

Frequently asked questions

What number flashcards should a kid learn first?

Most children start with counting to 20, recognizing digits, and matching digits to number words. Once that feels steady, move on to comparing numbers and simple addition within 10.

How many number flashcards should a child practice at once?

Around 10 to 15 new cards per session works for most young learners, with older cards mixed in for review. Short daily sessions of about 10 minutes usually beat one long session.

Can I print the flashcards DeckOwl makes?

Yes, but exporting to PDF is a Plus feature, which costs $39 a year or $7.99 a month. The free plan lets you study the cards in the browser.

Does DeckOwl work from a photo of a worksheet?

Yes, photos of pages are read with text recognition, so you can photograph a worksheet and generate cards from it. Check the cards afterward for any misread numbers.
