The Flexible Zone is a program that aims at both the better and balanced distribution of the kindergarten's material and the feasible interdisciplinary approach to knowledge. Within this Zone, thematic units are developed, which stem from the experiences, interests of our students and cannot be easily projected or promoted at the level of formal teaching. This program is based on the reform of school time and the cultivation - development of critical thinking, cooperation, collective effort, and experiential action. The Flexible Zone is used as a means of a better interdisciplinary approach to another generally accepted and anticipated perception according to which the school should become a place of joy and life and not only of teaching and acceptance of fragmentary knowledge.
