Abstract
Since Euler’s polyhedron theorem included in topology was newly added in the current national courses of study for Mathematics A, we selected twelve topics on topology, and lectured college students that aimed to a teacher about these topics in omnibus form. In this study, we have obtained the result that nine of twelve topics interest many students. Moreover, the results of this lecture show that it is highly probable that students will be interested in topics at the contents of figures with models of polyhedrons and balls, and to give mathematical interpretation for a real phenomenon.
