I didn't see any development at all.
Maybe it would help if you gave us the student's reaction. When you say "An analog clock has a sweeping second hand and a digital clock flips through the digits.", how do they respond?
It seems like you are doing nothing more than teaching through example the common use of the phrase "continuous motion", although, second hands generally jump, not sweep, because of the escapement. All of this dialog of yours looks very much like you showing the students common uses of the word "continuous". Given what you have posted so far, this is a language arts class, not a math class. Maybe if you provided the students' side of this dialog it might help us distinguish it from language arts.
