Abstract : We report on activities and progress in a European (Comenius 2.1) project "LTMLearning Tools for Mathematics" that creates multilingual learning units on the basis of Mathematica and M@th Desktop. A customized user-interface based on palettes is optimized for use in class, and notebooks provide associated math content with a strong emphasis on visualization. The multilingual nature of the learning units makes them useful for transnational school collaboration projects, as has been demonstrated in a pilot project. The problems and exercises are oriented towards applications and encourage explorative group projects. This leads, in particular, to an improved image of mathematics and math instruction among students.
