I gave and recorded the presentation using Google Hangouts On Air:
The presentation is here and the spreadsheets referenced in the video are available here.
Unfortunately the audio on the other end wasn't working, so I was not able to do the question-and-answer session that I had planned. In lieu of that, I'll follow up with the students using a Google Form to collect their questions and I'll post the answers here.
I have been subscribing to a lot more YouTube content lately, and I like the concept of preparing a series of short personal finance videos to add at the top of my posts here. These videos could give the tl;dr version for people who prefer the sound of my voice to my writing style (what a choice!).
My public speaking needs work, but to be fair this was 6AM my time...
