ab: Summary: Card tricks based on mathematical principles can be a great way to
get students interested in exploring some important mathematical ideas.
In this article, the author discusses a simple spreadsheet
implementation that shows students why the card trick works and allows
them to explore several variations. As an added bonus, students are
introduced to composite functions, the floor function, and iteration,
and they learn how to use formulas and the INT function in Microsoft
Excel. The depth of the mathematical explanation can be varied
according to studentsâ€™ background. (Contains 5 figures.) (ERIC)
