Complete volume for lower secondary education – suitable for use in Bremen, Hamburg, Hesse, Mecklenburg-Western Pomerania, and Saarland. The textbook is systematically structured by subject and fully covers the current curricula with all their requirements.

Main chapter introduction: An image prepares the students for the new learning material and provides an overview of the topics. A new topic begins with a motivating introductory image on the first content page and a short text that ends with a question. The content pages primarily serve to convey the subject competencies. In addition, technical terms are explained and the introductory question is answered.

Material pages: With complex, material-based tasks, students deepen and connect their knowledge and explore new topics. All tasks in the book are marked according to levels of difficulty, supporting differentiated instruction.

Focus pages open up new contexts for deepening understanding and often establish interdisciplinary connections.

The new page type "At a Glance" summarizes what has been learned at the end of each topic complex with a structured overview.

The new Check-up pages allow students to review the competencies they have acquired. Using the solutions in the appendix, students can check their own work.

The glossary explains important technical terms.

Each chapter is enriched with QR codes linking to additional digital material, enabling hybrid teaching between print and digital.
