The TERRA Geography Student Book for Lower Saxony is aimed at learners in the 5th and 6th grades at secondary schools and provides a comprehensive foundation for geography education. It promotes individual learning success through a competency-oriented approach that supports self-directed learning. The content is designed to allow for both performance and elective differentiation, addressing diverse learning needs. The book includes numerous opportunities for self-directed learning, such as learning tasks and station-based learning, which help students deepen their knowledge independently. Additionally, it offers an improved task culture that provides a clear distinction based on task purpose and presents a variety of practice and application situations. The integration of new digital possibilities and the enhancement of education for sustainable development are further key aspects of this teaching resource. An extensive supplementary section with a Haack map section complements the content and provides additional resources for teaching.
