Revised edition for G9 according to the new core curriculum in Geography for the 2015/2016 school year. New concept: The proven double-page principle has been retained, but now the left page primarily features the fundamental geographical knowledge, while the right page mainly includes materials, exercises, and tasks. Each chapter focuses on a core theme (e.g., Chapter 1 on Core Theme 4). Different areas of competence: Certain tasks are highlighted as transfer, active, and discussion tasks. For particularly difficult tasks, students will find solution aids in the appendix of the textbooks. Subject-relevant working methods are taught on designated double pages. Some central geographical ways of thinking (e.g., recognizing systems) are introduced in a student-friendly manner on selected pages.
