How many cards is it, exactly?

112. That number is read from the file itself, so it cannot drift from what you get. 112 cards: 48 exact values (16 standard angles × sin, cos, tan) and 64 identities, conversions and definitions. That is the whole unit-circle syllabus.

Can I edit the cards?

Yes — that is most of the point. Buying the deck gives you a link that loads all 112 cards into the free flash card maker on this site, where you can reword a definition, delete the ones you do not teach, add your own, change the layout, and print. The first 20 cards load for free without buying anything, so you can try that before you decide.

How do I print them double-sided?

Print double-sided and flip on the LONG edge. Every front sheet is followed by its own back sheet, already mirrored for that flip — print them in the same order as the fronts and every answer lands on the wrong card, which nobody discovers until sixty cards have been cut apart.

Can I use it with more than one class?

Yes. The licence covers unlimited printing for every class you teach, for as many years as you teach them. It does not cover reselling the file or passing it to colleagues.

Look inside

Building real pages…

Every exact value on the unit circle plus the identity sheet, with the signs checked.

Eight cards to a sheet with cut guides, and every front sheet is followed by its own back sheet with the rows already mirrored — so you print double-sided, flip on the long edge, and the answers land on the right cards. That one detail is the thing teachers report getting wrong when they build a deck themselves.

The deck is also content, not just a file: a link on your download page loads all 112 cards into the free flash card maker, where you can reword anything, drop the cards you do not teach, add your own, and re-print at any size from two to nine cards a page. The first 20 cards load for free, before you buy, so you can see exactly how the cards are worded.
