I will be coaching the Putnam participants at University of Ottawa this year. Email me if you are interested.
Paul Lockhart's argument for scrapping the mathematics curriculum. It's worth all 25 pages of reading.
Combinatorics, broadly speaking. This includes graph theory, algebraic graph theory, association schemes, and matroids.
Some interesting reading (in random order):
Some discrete resources (in random order):

A nice commentary on helmet laws for cyclists. And a short CBC piece on New York's Vision Zero approach to cycling (and pedestrian) safety.
From the Pew Research Center: projections of religions and population growth.An article in the Atlantic about the 9.9%.
Marian Rejewski should be better known than he is for his pivotal role in breaking Enigma, and his colleagues Henryk Zygalski and Jerzy Różycki. Students in mat2143 might note that some of Rejewski's methods used permutation groups.
Map of wildfires in BC.
A letter from the FBI to MLK, and a New York Times Magazine article about it.
An old (2006!) post by Bruce Schneier on online privacy. It's still highly relevant a decade later (which is what you'd expect from him). On an interesting historical side-note, count the number of trolls, unrelated posts, random poltical shills and general sock puppets in the comment section.

A video summary of 1945–1998. Check out the cafe or the turtle. A recent episode of radiolab looks at those on both ends of nuclear weapons.
A musical discussion of transit fares and some background.
A nice discussion of PowerPoint. True, I don't personally launch space shuttles but the argument is more widely applicable. Don't miss out on the analysis of the powerpoint slides a little way down.
A site dedicated to Canadian election forecasting
Some interesting graphs about Canadian debt and deficits, and a more up-to-date version.
