Networks and Graph Theory
This feature introduces students to the topic of networks, which has many real life applications.
The problems in this feature will encourage students to experiment, conjecture and deduce general relationships for networks in different contexts.
You can find out more about real life applications of networks in these Plus articles.
You can also watch a recording of the webinar in which we discussed the mathematical thinking which can be prompted by these activities.
