The interdisciplinary learning and workbook addresses topics that always start from the concrete experience of the students. The tasks encourage learning with all senses. Newly developed features include: new method pages for the step-by-step introduction of work techniques and subject-specific methods, new activity pages that encourage independent, smaller research, experiments, or projects, as well as compact pages at the end of each chapter for practicing and consolidating what has been learned in a motivating and playful manner. A special advantage is the significant expansion of geographical and historical topics. There are now 50 more pages of history and geography in Volume 1.
