Topic: Graph Theory
Presenter: MathHappens’ own Elizabeth Wrightsman.
Twenty Three girls participated in this hour and half session. We learned about the history of graph theory, starting with the Bridges of Koenigsberg, covered a variety of interesting vocabulary including bipartite, incomplete graphs, tree graphs, forest, cupboard folds, cycles, vertices, faces, edges and more. The slides are here.
Next we spent some time learning to make a Sonobe cube. You make six pieces and put them together. The directions for the folds are here along with a second page that shows how to build the puzzle pieces for a Somo cube. Directions are here.
Reviews for the session were great! Average rating was 4.4 out of 5, difficulty 3.1/5 and most important, enjoyment was 4.6 out of 5.
