Graph Theory: Puzzles and Games
This resource is a set of worksheets about games and puzzles based on simple concepts in graph theory. The resource covers: the seven bridges of Konigsberg, the Shannon Switching game and graph vertex colouring.
This resource aims to provide a very basic introduction to graph theory. The activities are designed to get participants to become familiar with how problems can be simplified into graph theory problems and how that may be used to find solutions.
These materials were originally designed for public engagement and do not require much formal mathematical knowledge beyond counting. Although the topic of graph theory is beyond the scope of many mathematics curricula, it is fairly accessible as the problems can be clearly understood visually (e.g. colouring, drawing paths). This resource aims to develop logical thinking and problem solving skills while introducing the participants to a new side of mathematics.
