AN INTRODUCTION TO GRAPH THEORY USING EVERYDAY PROBLEMS

Graph Theory. Classic Problems. Algorithms in Graphs. Everyday Problems. Basic education. Didactic Sequences.

In this work, we present some introductory concepts about the theory of emphasizing the classic problems and the algorithms developed from les. In addition, we try to provide the elementary school teacher with material, involving Graph Theory, which provides the high school student with greater interest in mathematics. Books, articles and dissertations served as a basis theoretical to offer the reader, especially the mathematics teacher of teaching basic, a material that allows an approximation with this theme. For this, we put didactic sequences developed from the problem solving approach problems, so that in each of them problem situations are presented challenging, involving activities present in the students' daily lives and seeking arouse the interest of students. With these activities, we believe that information clause of the Theory of Graphs are seen as one more alternative of content to be worked with Basic Education students, and without major obstacles, because it meets expectations of the National Curriculum Parameters for the applicability of knowledge acquired in solving problem situations encountered in daily life, in addition to to be a gateway for the presentation of new content.
