Looking for PGN examples to teach beginners chess fundamentals

I'm starting a chess club at work and I would like to use my chess.com account to help teach the beginners some basic chess fundamentals. Are there any preloaded examples I can use to help with this? Specifically, I'm looking for middlegame tactical positions like forks, pins, and skewers that I can easily load using the analysis board. Does anything like that exist on chess.com? If not, does anyone know where I can find some of these as PGN files to load? TIA!

Thanks Treesong! I'll look into these.

So these appear to be full games. I'm looking more for PGN files that demonstrate tactical positions. Does something like that exist, or do I need to wade through a bunch of games to find examples?
