CurriculumPLUS Bavaria ZN 118/14-GS. A central innovation in CurriculumPLUS is the consistent focus on competencies. This is implemented consistently in "The Math Book." Both content-related competencies and process-related competencies such as reasoning, communicating, and problem-solving play a significant role in "The Math Book." The various competencies required in the area of practical arithmetic are developed with the children continuously and step by step from grade 1. In the area of geometry, there is a focus on promoting spatial skills. Mastery of these skills is an important foundation for successful mathematics learning. Each chapter concludes with a "Practice and Review" page, which checks the minimum standards. This page is complemented by a "Reflect and Deepen" page, which serves to review previously learned content and also includes tasks from requirement areas II and III. In summary: Consistent competency orientation according to CurriculumPLUS, all subject areas of CurriculumPLUS weighted appropriately, differentiated tasks from all three requirement areas of the educational standards, rich task formats, practical arithmetic course starting from grade 1, topics of chance, probability, and combinatorics considered from the beginning, targeted promotion of spatial abilities, "Practice and Review" pages for checking minimum standards, "Reflect and Deepen" pages for reviewing previously learned content, modern layout, appealing illustrations.
