I have just finished the first few days worth of problem sequence for my IBL liberal arts math class, *Mathematics in Decision Making*.

This part of the course will rely heavily on a previous iteration by my colleague Doug Shaw. I have also stolen a nice problem from my colleague Adrienne Stanley.

This portion of the problem sequence aims at the idea that it is possible to compare the cardinalities of two sets without counting either one. Most of the problems are about finite sets and have a distinctly combinatorial feel— this is Shaw’s influence. I expect that this will take three or four class meetings to get through.

The problem sequence is available here in my public Dropbox folder.
