Some ideas on how to teach it non-verbally in class, regarding the add, commit, push workflow: In class I'd stand on my right side, so students see me on the left (people are more used to left to right motions because of reading). I'd demarcate the working directory, staging area and local repository non-verbally as 3 different spaces. My most right space (the student's left) was the working directory, my most right space (the student's right) was the local repository. Everytime I'd make a transition from one space to another through add or commit, I'd make a hand gesture when I'd say "add" or "commit". In order to add some humor (humor is rememerability) with push I'd point upwards to the ceiling as if I were looking to God. I'm not religious, but people got the reference and they all left out loud.
