The tasks in the mathematics curriculum of high school are diverse in 6th grade and become increasingly complex. This learning aid allows students to review and deepen their understanding of content through mnemonic texts and various types of exercises. It includes exercises in the following areas: rational numbers, fractions, calculating areas and volumes, working with data and probability experiments, percentage calculations, and diagrams. With the removable answer section, students can check their own results, making their strengths and weaknesses visible, allowing for targeted practice. This way, everyone is well-prepared for the next test at school.
