Light, Math, and Color – 2017 Projects

I just finished teaching another Light, Math, and Color minicourse. Twenty students researched a math topic and illustrated it with a stained glass window. Their projects this time around are really spectacular, especially considering these are first tries. (Note: If you hover over a picture, the math topic it illustrates will show up.)

The BBC Does Mathematics


I’ve discovered a nice podcast that is produced by the BBC: In Our Time. Melvyn Bragg hosts a different group of guests every week, depending on the topic being discussed, which can be anything related to the history of ideas. I’ve enjoyed hearing how the Book of Common Prayer came to be, the significance of George Orwell’s Animal Farm, and how radio was invented, among many interesting topics. Melvyn keeps things moving along, and the guests are always very knowledgeable and entertaining.

Of course, I most enjoy the math-related conversations, so for my fellow math teachers here is a list of the programs – at least the ones I’ve found so far – that are devoted to that subject (click on the title to go to that program’s download page):

Algebra 2 Screencasts!

I’m teaching Algebra 2 for the first time in many years, so I am recording lots of screencasts for it. I’m putting them into a YouTube playlist, and you can access them all here. So far, I’ve covered completing the square, linear inequalities, radical and quadratic form equations, absolute value equations and inequalities, solving quadratic equations, basic tools of graphing, lines, circles, function basics, graphing functions, transformations, and functions operations and composition. (Whew!)

If you’re really bored and want to binge-watch them, here you are:
