I am looking for an introductory book in Topology, but one meant for a younger audience than is usually the case :
I am planning to do a reading course with some sophomore students and I would like to motivate them to take up mathematics as a major. They have seen Apostol's Calculus, some Linear Algebra (a la Hoffman & Kunze), and some Group theory (a la Herstein). ie. They are not unused to rigour, but might be a little daunted by too much of it.
Therefore, I would like to do some serious mathematics with them, but with a view to get them interested in geometry/topology (They chose this topic based on advice from some older students).
Some topics I had in mind were :
a) Wallpaper patterns/Platonic solids and their symmetry groups
b) Euler's theorem for polyhedra ($v-e+f = 2$)
c) A gentle introduction to the fundamental group
Could anyone suggest a good book to follow? I can only think of Armstrong's Basic topology, which I will follow in the absence of anything better, but some of you out there probably have some experience doing this (in summer math camps and such). Any suggestions?
