Recreational Mathematics

A lot of my work with curriculum development and pedagogical technology bleed into the area of recreational mathematics, which I have always found to be an engaging way to introduce mathematical ideas. As a long time fan of Martin Gardner from the points of view of both mathematics and magic, many of the items below are connected with things I read in his books and articles.
