The Story of Maths
Here's a cool series to show in class if you can fit it in (or just to watch yourself). The first two episodes are appropriate for a wide range of skill levels, visually engaging, and emphasize the multicultural history of math. The next two give an overview of the development of math within the last 400 years or so, as the narrator visits sites of historical significance. The Newton-Leibniz piece would be great to show at the outset of a calculus class, or when discussing the notation for derivatives. The final disc explores prime numbers and the Riemann hypothesis, which holds special significance to the narrator, Marcus du Sautoy.
