Cut out all the excess verbiage: be ruthless!
Teachers tend to be an erudite lot, with the ability to wax lyrical at the drop of a hat. But there's a good reason that teachers and leaders of computing in particular should develop the habit of being concise.
Walk the talk
The best programs are efficient. Extraneous code may add a few microseconds on to the running time, so programmers lean towards, er, lean programs. It seems to me that that is a useful habit to carry over into everyday school life, whether in the form of instructions or please for extra cash. Writing lean prose is a way of demonstrating that you can practice what you preach, even in a different context.
