I've taught illustration/animation classes as an adjunct at the local community college for many years. A few years back I started taking one class period during the semester to go way off topic and into basic personal finance, giving a lecture/discussion which I call Money 101. I've presented portions of it to high school classes I've spoken with as well, and the topics covered were well received.
Here's a link to the Evernote outline (with links) I created for that talk. Feel free to use/share any of it if it helps you in planning your talk.
Money 101
I was spurred to do it after reading an Atlantic cover story from 2016 detailing how many folks would have trouble coming up with $400 to cover an emergency. Knowing most of my students come from modest means and faced the imminent possibility of making large financial decisions (cars, student loans, etc.) they may not be prepared for (but might have a huge impact on their futures) I thought it could be a class that had much more relevance to them than anything else I covered the rest of the semester. I was correct, given the feedback I've received from the students each semester I've presented the talk/discussion.
