Hello again Polycount, some time ago I made a website to teach about the basics of UV mapping, there is two pages of content about the basics and there is a third page where you can unwrap primtives in your browser with a scoring system.
https://uv-game.com/It also works on mobile but it depends on the capabilities of your phone. For those who want to know how I made the UV mapping tool, Three.JS (and a lot of maths).

Now if I need to explain how unwrap works, I can just send a link. Sweet.
