The folder {\it Gaussian and Mean Curvatures at the Regular Point of
  a Surface},  a part of  the geometrical educational material
designed within IT Project {\it Selected Chapters of Geometry and
  Mathematics with Mathematica}, will be presented. The folder contains
  HTML, {\it webMathematica} and {\it Mathematica} files  whose purpose
  is to improve students' understanding of the terms related to the
  normal, Gaussian and mean curvatures of a surface. The working
  version of the folder can be
  found at the following address: http://www.grad.hr/itproject\_math.
