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. The resource is aimed at a general public level as formal mathematical knowledge is not required beyond counting, but younger audiences would need more guidance. 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. In this resource: Graph Colouring: solving scheduling and allocating problems using graphs Instructor guide 4 Party Problems 3 Radio Problems Rivers and Bridges: based on the Bridges of Konigsberg problem Instructor guide Matching activity Worksheets for 4 real cities (including Konigsberg) Shannon Switching game: a simple game which is played on a graph Instructor guide PowerPoint explaining the game (with presentation guide) 4 Virus games Simple examples Design your own graph to win the game This resource was originally developed for the Edinburgh International Science Festival with the School of Mathematics.

A set of three posters aimed at Primary School learners that lay out different techniques for finding averages, using the example of Pokemon Hit Points. The posters cover mean, mode and median methods, include graphs to visually show averages and information about the advantages and disadvantages of each. Also included are versions of the posters that are editable in PowerPoint. For these to display correctly users will need to download the free font ‘Pokemon Normal’ designed by Neale Davidson (available on urbanfonts.com). Key words: Mean, Mode, Median, Average, Graphs, Pokemon Created as part of the School of Geosciences’ Outreach Programme, which allows students in their final year to work in partnership with a local school to develop a set of lesson plans.
