Helping a trainee find something to prepare for live demonstration

We helped a trainee find something for live demonstration when even spreadsheets are not yet familiar to them:

- What are things you do or teach people to where you demonstrate something?
- Is there something you've helped someone with in office hours recently?
- Do you help people fill in any sort of template or use project

The issue names no file, test, or entry point to inspect. Start by clarifying what live-demonstration material or activity should be added, where it belongs in the instructor training materials, and what completed guidance should contain.
