Welt der Zahl 4. Schulbuch. Für Berlin, Brandenburg, Mecklenburg-Vorpommern, Sachsen-Anhalt un

The revised edition of "The World of Numbers" emphasizes a clear structure and calm, well-organized pages. In addition to the color-coded content areas and special recurring pages (e.g., "Calculation Olympics"), symbols help navigate the textbook. The table of contents outlines the process-related competencies to be acquired. The task number directly indicates the level of difficulty for each task. "The World of Numbers" provides suggestions and opportunities for both individual independent work and group or partner work in the spirit of cooperative learning. Through meaningful learning activities (discovery tasks), children are encouraged to explore their own paths, articulate them, and reflect together. Motivating task formats offer a gentle progression of difficulty, allowing for natural differentiation. Numerous partner games encourage children to communicate with each other while practicing and reinforcing previously covered content in a playful manner. Important content and terms are recorded on the pages in word banks, which connect technical language with fundamental concepts. The word banks help children build and gradually expand their technical vocabulary. The revised edition also incorporates the idea of "Active Learning" through motivating movement games, particularly focusing on "learning through movement," where physical activity enhances understanding of the learning material. The textbook for grade 4 includes a supplement that can be purchased in a set of ten: number cards 0-9.
