Why generate your own ordinal number cards
Ordinal numbers trip up many learners because the suffixes change in ways that are hard to memorize from a list. A printed sheet of ordinal number flashcards shows the answers but cannot adjust to the exact rules your class covers, such as teen numbers or fractions.
- Suffix rules: first, second and third are irregular, while 4th through 9th take -th.
- Teen numbers 11th, 12th and 13th always use -th, even though they end in 1, 2 or 3.
- Fractions often start from ordinals, so cards on thirds and fourths help with both topics.
- Write ordinal words and numerals on the same card so you practice both forms.
Built from your material
Upload a PDF, slide deck, text notes or a photo of a worksheet. The cards cover your teacher's examples, not a generic list.
Spaced repetition
Cards you miss come back sooner, and cards you know fade into longer gaps, so review time goes where it is needed.
Export when you need a file
Plus exports your set to PDF, DOCX, Anki or CSV for printing or a second app. The free plan stays in the browser.
How it works
Upload your file
Add a PDF, DOCX, PPTX, notes or a photo of a page. Text in photos is read with text recognition.
Review the flashcards
Check the ordinal number cards DeckOwl generated and edit any that need a clearer answer.
Study or export
Study in the browser with spaced repetition. On Plus, export the set as a PDF to print.
Generating cards from your own notes keeps the set aligned with your course. Upload the handout or slides you already have, then drill the items you miss until they stick. Printing the result as a PDF is available on Plus.

Frequently asked questions
How do I remember ordinal suffixes like 2nd and 3rd?
Learn first, second and third as irregular words, then the pattern -th covers most other numbers. Teen numbers like 11th, 12th and 13th are the common exception to the 1, 2, 3 rule.
What is the difference between ordinal and cardinal numbers?
Cardinal numbers count how many things there are, like three apples. Ordinal numbers give position or order, like the third apple in the line.
Can I export my ordinal number flashcards to PDF?
PDF export is a Plus feature, which costs $39/year or $7.99/month. The free plan lets you study generated cards in the browser but does not include exports.
