At the beginning there will be told some words about the sense of mathematics education and different conceptions of teaching mathematics as well as different approaches to mathematics. In connection with this the conception of the "practice-orientated-mathematics-education (PROM" which the author formulated will be commented. This conception - which must be seen as one point of departure side by side with others - has the aim to qualify the pupils to master life and bases on the method of working on the problems true to life. In the second part it will be discussed how this conception fits with geometry teaching and it will be listed several problems and objects of everyday life in which geometry is of importance. After that experiences with some units of teaching geometry in everyday life in school will be explained.
