Several decks are available on Mathwire for downloading as PDFs. All decks are 30 cards so that there are enough cards for most classes. In fact, some students will probably need to have two cards to use the complete deck. The decks are designed to print onto 2x4 inch labels (10 to a page). These can then be affixed to index cards to create each deck. If labels are not available, simply cut and paste the printout to create card decks.
