Colors and symbols clearly indicate three different levels and tasks for training process-related competencies. Each learning unit includes basic tasks with many examples as well as advanced tasks. Different approaches facilitate the entry for various learning types: whether through discovery based on everyday and intra-mathematical questions or through reading with example-related teaching texts - mathematics enables all learners to engage in understanding and active learning. The thematic pages encourage interconnected application and interdisciplinary, project-based work. Method pages train mathematical reasoning and the use of mathematical tools.
