The following task can initiate a reflection upon the selected solutions:

Which mathematical terms and concepts have we used in the processing of the task?

Represent it clearly in a chart!

Represent it clearly in a chart!

A joint brainstorming session with the class to gather as many ideas as possible is recommended.

Below you see a possible networking chart. It does not contain all conceivable networks due to reasons of clarity.
