Teaching the general theory of relativity to high school or
undergraduate students must be based on an approach that is conceptual
rather than mathematical. In this paper we present such an approach
that requires no more than elementary mathematics. The central idea of
this introduction to general relativity is the use of so-called sector
models. Sector models describe curved space the Regge calculus way by
subdivision into blocks with euclidean geometry. This procedure is
similar to the approximation of a curved surface by flat triangles. We
outline a workshop for high school and undergraduate students that
introduces the notion of curved space by means of sector models of
black holes. We further describe the extension to sector models of
curved spacetimes. The spacetime models are suitable for learners with
a basic knowledge of the special theory of relativity.
