Lambacher Schweizer 9/10

This volume is aimed at high schools and covers the material from the 9th and 10th grades. The content for the Swiss edition of "Lambacher Schweizer" is based on the current series "Lambacher Schweizer" from Ernst Klett Verlag. The selection of content was made based on cantonal and school-specific high school curricula, as well as the recommendations of the Swiss Maturity Commission and the HSGYM working group. The common underlying idea is to convey competencies instead of isolated calculation operations. The new "Lambacher Schweizer" offers a student-friendly and carefully structured course through mathematics. Introductory pages, varied task materials, special pages, and thematic topics enable meaningful, understanding-oriented, and interconnected mathematics learning. The textbook encourages active engagement with mathematical content and strengthens methodical learning. Students learn to understand real-life situations, recognize relationships, and decide on the choice of appropriate mathematical tools.
