We usually have the kids make a rectangular block with a rectangular pocket, 2 blind tapped holes, 2 clearance holes that are counterbored for #10, and a 0.547" hole in the center (bored out with a boring head). That usually teaches the kids the basics of running the BP.
IMO the best way to teach apart from that is to have them make actual robot parts, maybe for an offseason project.
I'll see if I can find the curriculum we used for the community college machining course I took a couple years back... that one was fast paced and covered everything.
EDIT: Clickspring is great if your students are really into art or aesthetics, I love his channel. Tom's Techniques is great for when you want to look up specific processes. Apart from those he mentioned I also use "This Old Tony" as his videos have a lot of humor in them while remaining useful. He also speaks faster than some of the other machinists on Youtube, which is nice for students.
DOUBLEEDIT: Found the curriculum used in the course:
