The Euler Archive
This is a great on-line resource hosted by the Math Department at Dartmouth University: a comprehensive collection of the works of (and about) Leonhard Euler.
http://www.math.dartmouth.edu/~euler/
Euler, indisputably one of the greatest mathematicians in history, authored over 800 papers in his lifetime, touching on every area of mathematics then in existence. In addition, Euler made significant contributions to physics, astronomy, and applied sciences as well.
The archive features historical and biographical information, related resources, and digital copies of over 800 original documents.

Geometric Estimation Game
This is a ton of fun: a geometric estimation game!
Given a variety of scenarios, your job is to eyeball various geometric constructions like midpoint, angle bisector, and point of convergence.
The game not only times you, but it measures your error in units and keeps a running tally on your average error!
What a great way to develop geometric intuition! Or while away a little bit of time.

Mathematical Documentaries
This is a nice collection of mathematics-themed documentaries:
http://www.cosmolearning.com/mathematics/documentaries/
There are 30 or so documentaries here, many from the BBC’s Topics in the History of Mathematics, such as Non-Euclidean Geometry and the Birth of the Calculus.
Other documentaries of interest include biographies of Florence Nightingale (whose contribution to statistics is often overlooked) and John Nash (Nobel prize winner and subject of the film A Beautiful Mind).
There are also a number of traditional lecture series available as well.

Math Lesson: European Debt Crisis
My latest contribution to the New York Times Learning Network is a Math Lesson designed around exploring loan repayment and risk assessment in the context of the European Debt Crisis.
In this lesson, students interact with some cool infographics, collect debt data, run the numbers on possible loan repayment schedules, and explore an elementary notion of “risk” in finance.
