As the central medium of the series the textbook pursues an approach in terms of conception and design which leads to mathematical definitions and procedures through everyday situations and tasks. It supports a teaching culture which transcends the dominance of the basic pattern «short introduction algorithmic core (theory segment) practice» in favour of a variety of methods with open and student-active forms of learning. The tasks to this end are short and varied they not only enable learners to work through the material operatively but also include applications and connections as well as exercises for the shaping of routines.
