Turn any worksheet into number flash cards for kids
Printable number charts are fixed. Upload the worksheet your child is working on and get cards that match their lesson, with spaced repetition for the numbers they miss.
Why custom number cards beat a generic chart
Most printable number charts show 1 to 100 on one page, but a child learns faster when the cards match the numbers in their own class. DeckOwl turns a photo of a worksheet, a PDF, or typed notes into number chart flash cards for kids with spaced repetition, so the ones they miss come back sooner.
- Counting cards that start at any number your child is learning
- Number word cards that pair digits like 14 with fourteen
- Place value cards that ask how many tens or ones are in a number
- Skip counting cards for 2s, 5s, and 10s taken from your worksheet
Built from your material
Upload a photo of a worksheet, a PDF, or typed notes and the cards follow what your child is learning this week.
Photos work too
Snap a picture of a classroom number chart and the text is read so you can turn it into cards without retyping.
Spaced repetition
Numbers the child misses come back sooner, so practice goes to the hard spots instead of the ones they already know.

Frequently asked questions
What number skills should kids practice with flash cards first?
Most children start with counting to 20, recognizing written numbers, and reading number words. Once those feel automatic, place value and skip counting by 2s, 5s, and 10s are good next steps.
How many number cards should a child study in one session?
Ten to fifteen cards is a comfortable session for most young children, with the missed ones repeated at the end. Short daily practice tends to work better than one long session.
Can I print the flash cards?
PDF export for printing is available on the Plus plan at $39/year or $7.99/month. The free plan lets you study the cards in your browser.
Is there a free plan to try it?
Yes. The free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start.
