And I hope and pray you are teaching them
f-stop printing...
"Our Father (or Mother, as appropriate):
Please lead this teacher and his pupils in the paths of righteousness.
Forgive them any transgressions of linear time.
As we know you are logarithmic,
And have commanded us to
go forth and Multiply, not add.
Amen."

I taught them the linear way first.
Then I said, "Hey, I have a slightly different way I want to show you, but it's a little more difficult with these timers..." (They're not using the really large Gralabs, but the smaller Time-o-Lite ones, so it was just a bit harder to see and change the time each time. There are no digital timers.)
I told them they didn't have to use the method if they didn't want, but I wanted to show them both ways so they could make a decision.
Then they made a test strip and we compared them. They could very easily see the difference. Then we discussed the math behind it (which took a bit of discussion) and how that relates to lens f/stops, shutter speed, and ISO.
Basically, I taught them the linear way first to sell them on the f-stop way later. (Which worked.)
Unfortunately, my time with them was limited, so we didn't get to go very in depth, but I'm leaving them with a packet of information so they can keep exploring. The goal was to get them more comfortable in the darkroom, and to get them understanding the basics of using the darkroom--and I'm talking basics, like how to make sure your negatives are emulsion side down, how to NOT fog an entire box of paper, etc. They've definitely learned that and they're excited to keep making prints and moving forward.
As I hoped, as soon as they made one even partially decent print, they were excited to keep printing. We all lost track of time and not one of them checked their phone for several hours. Hey, the power of the darkroom.
So I'm hopeful that things are off to a good start.
Thanks again to everyone in this thread for your suggestions and information--very helpful!
