Why custom rational number flashcards beat printable sets

Students working through fractions, decimals, and square roots often need a deck that tests whether a number is rational, not just how to solve one problem. Upload your own class notes, slides, or a photo of a worksheet and DeckOwl generates rational number flashcards you can review with spaced repetition.

Definitions of rational and irrational numbers taken from your course notes
Cards for terminating, repeating, and non-terminating decimals
Practice classifying integers, fractions, and roots from your own examples
A deck that comes back on a spaced schedule as you study

Example rational number flashcards for grade 7 math

Is 0.75 a rational number?Yes. It equals 3/4, so it can be written as a ratio of two integers.

Is the square root of 2 a rational number?No. It cannot be written as a fraction of two integers, and its decimal expansion never terminates or repeats.

Is every integer a rational number?Yes. Any integer n can be written as n/1, so it is a ratio of two integers.

Does 1/3 have a terminating decimal, and is it rational?No, it is 0.333 repeating. It is still rational because it is the ratio of two integers.

Is zero a rational number?Yes. 0 can be written as 0/1, and the denominator is the only part that cannot be zero.

Generate the full set

Starts from your material

Upload PDFs, DOCX or PPTX files, plain notes, or photos of a worksheet. Cards follow the definitions and examples your teacher actually used.

Spaced repetition

Cards come back at the intervals that help you retain them, so classifying fractions, decimals, and roots stays fresh before a test.

Study anywhere

Review in the browser on the free plan. Plus adds PDF, DOCX, Anki, and CSV export for printing or moving decks into other apps.

How it works

Upload your notes

Add a PDF, slides, a text file, or a photo of a page on rational numbers. Text recognition reads the images.

Generate the cards

DeckOwl turns the material into flashcards. Check a few against your notes to confirm the definitions match your course.

Review on a schedule

Study the deck with spaced repetition and focus on the cards you miss, such as deciding whether a square root is rational.

Cards built from your own material match the examples your teacher used, which makes them more useful than a generic printable set. Review the answers against your notes before a test, since any study tool can make mistakes.

Frequently asked questions

What makes a number rational?

A number is rational when it can be written as a fraction p/q, where p and q are integers and q is not zero. Terminating and repeating decimals are always rational.

How many flashcards should I make for a rational number unit?

Aim for one card per definition or rule, plus one per example type, such as classifying 0.75 or the square root of 2. Most units work well with 20 to 40 cards, split into smaller decks.

Is the free plan enough to make these cards?

The free plan includes 3 generations per month and studying in the browser. Exporting to PDF, DOCX, Anki, or CSV requires Plus, which costs $39/year or $7.99/month.

Can I export my rational number flashcards to Anki?

Yes, the Plus plan lets you export to Anki, along with PDF, DOCX, and CSV. Students with a school email get 40% off.
