I grew up in the era post American muscle. Most every kid had a small beater car and they were all stick. Remember when you were charged more for an automatic at the dealer?
My daughter was given a free car by a family member, a Fiat 500. Terrible little car but she loves it and of course, a 5 speed.
I taught her in 3 1/2 hour lessons. First in an empty parking lot and moved to a country back road where we just pulled to the side if another car came along. Just clutch work over and over, then 1st to second and stop. Do it all again. 1st to 4th over and over. Do it all again.
Couldn't take the car alone until she was proficient on good inclines. I took her to a 45% hill to show her it was possible but beyond her at this point. I still hear kids would alter their routes to not be at hills at a stop light....my wife tried to tell her to use the parking brake on hills; my daughter said no way I want to learn how to drive this properly
Patience and a sense of humor made it all work. An understanding that you're going to stall a few times. She's been great for a year+
