Clear structure. For each lesson unit, there is at least one basic page and one material page. Basic pages convey subject matter in an easily understandable and clear manner. With meaningful illustrations, concise texts, key phrases, a vocabulary box, and differentiated tasks, students grasp and reinforce the essentials. Material pages offer student experiments and task-based activities. This allows competencies to be acquired and applied in a student-centered and action-oriented way. The materials increase in difficulty, enabling all students to be supported according to their individual performance levels. Additionally, there are specially integrated supplementary pages. Method pages guide step by step in learning a method that is then applied on the material pages. The longer texts and more challenging materials on the Extend-and-Deepen pages specifically support higher-performing students. The most important information at a glance: the summary pages serve for review. Test-yourself pages consist of tasks for independent competency assessment. The differentiation concept is based on a comprehensive material pool for heterogeneous learning groups. Basic and material pages are in a 1:1 ratio, and the tasks are presented at three levels. With this offering, you have versatile options to prepare and design your lessons directly with the book.
