Get number flashcards 1 to 20 with pictures from any PDF or photo
Ready-made printouts often use clip art that does not match what your child is learning. DeckOwl builds flashcards from the worksheet or notes you already have, and you can start with no credit card.
Why build number cards from your own material
Free printable sets often show generic pictures that do not match the words or objects your child sees in class, so a custom option can help. DeckOwl builds number flashcards 1-20 with pictures from the worksheet or notes you already use. Upload a PDF, slide deck, or photo, and the cards are ready to review with spaced repetition.
- Pair each numeral with a countable picture, such as three stars for 3.
- Practice counting forward from 1 and backward from 20.
- Repeat the cards that were missed and keep the easy ones for quick review.
- Test a set in the browser on the free plan before deciding whether you need exports.
From your own files
Upload PDF, DOCX, PPTX, plain text, or a photo of a page. Photos are read with text recognition.
Spaced repetition
Cards you miss come back sooner, so study time goes to the numbers that need practice.
Quizzes and mind maps
Turn the same material into multiple choice, true/false, or short answer questions, or into a mind map.
How it works
Add your material
Upload a PDF, slides, notes, or a photo of a page with numbers on it.
Generate the cards
Create flashcards from that material and review the front and back of each card.
Study in the browser
Review on the free plan in the browser. PDF export is included with Plus.
Keep each session short. Show a numeral, count the matching objects aloud, then ask the child to say the number before flipping the card. Add one or two numbers they already know so review stays easy and confidence builds.

Frequently asked questions
How many number cards should a child study at one time?
Most early learners do well with five or six new cards at a time. Mix in a few cards they already know so each session feels achievable.
How do I help a child match a numeral to its picture?
Show the numeral, count the objects aloud one by one, and then ask the child to say the number before turning the card over. Repeat the pairing with different pictures so the number stays the same across contexts.
Can I download the flashcards as a PDF for free?
The free plan lets you study in the browser but does not include exports. PDF export is available on Plus at $39/year or $7.99/month.
Do I need a credit card to start?
No. You can start on the free plan with 3 generations per month and no credit card.
