Title Information: Structure The chapter introduction pages feature special photos as eye-catchers, providing a motivating start. The foundational knowledge pages convey subject knowledge with age-appropriate, well-structured texts and corresponding visual material. A line counter aids in orientation and simplifies working with the texts in class. The Material-Method-Practice (MMP) pages turn the book into a workbook. MMP pages introduce and apply the central subject methods. Another focus is on material-bound tasks, which encompass all competence and requirement areas. Gecko tasks are more challenging assignments marked with a gecko, accompanied by differentiation aids. Review and Understanding: Students review the subject content of the chapters based on the basic concepts. Test-yourself pages enable independent learning.
