  We present two add-ons for Mathematica for teaching mathematics to
undergraduate and high school students. These two applications, M@th Desktop
(MD) and M@th Desktop Tools (MDTools), include several palettes and notebooks
covering almost every field. The underlying didactic concept is so-called
"blended learning", in which these tools are meant to be used as a complement
to the professor or teacher rather than as a replacement, which other
e-learning applications do. They enable students to avoid the usual problem of
computer-based learning, namely that too large an amount of time is wasted
struggling with computer and program errors instead of actually learning the
mathematical concepts.
  M@th Desktop Tools is palette-based and provides easily accessible and
user-friendly templates for the most important functions in the fields of
Analysis, Algebra, Linear Algebra and Statistics. M@th Desktop, in contrast, is
a modern, interactive teaching and learning software package for mathematics
classes. It is comprised of modules for Differentiation, Integration, and
Statistics, and each module presents its topic with a combination of
interactive notebooks and palettes.
  Both packages can be obtained from Deltasoft's homepage at
