As an introduction to Steiner Trees, class members are challenged to find the shortest paths to connect multiple points. The teacher introduces the problem by showing how to connect three points. Groups then go outside and construct a meter square and try to find the shortest path possible to connect the four vertices. Groups that finish then must find the Steiner Tree for a rectangle. The activity is the final installment of a three-part series.
