Dear Ribideau:
I don't have any brilliant ideas for the exhibit but I can recommend a very
interesting book which may inspire you. It's called "A Mathematician Reads
the Newspaper" by John Allen Paulos. It's a collection of short pieces
centering around the theme of how a lack of math knowledge can inhibit our
understanding of daily happenings - as reported in the newspaper. I think it
could help percolate a lot of great exhibit ideas.
Good luck!
