At point A you defined the circuit very simply. You can define the circuit more clearly. A circuit is a closed path through which one or more currents flow. Series circuit has one current path and parallel circuit has multiple current paths. (1.2)

You have not made the difference between series and parallel circuits very clear. You may note that in a series circuit, current flows in the same path back to the source, and in a parallel circuit, current flows in multiple paths back to the source. Another is that in series circuit the equivalent resistances are added and in parallel circuit the equivalent resistances are added as inverse and the equivalent resistance is reduced.
The circuit solutions and details you mentioned were good. The sum of the equivalent resistances in the circuit and its demonstration is excellent. (3)

You have successfully completed the cable joint step at point c. A series of pictures and descriptions clarify the steps of your cable joint. You were very careful about the cable joint. (3)

In the last point you mentioned your teaching points. It was really nice that you mentioned the things you learned from the lesson in point form. Thanks for sharing your learning experience. (1.4)
