Features: The 21st century is the era of the knowledge economy, making the demand for innovation more urgent than ever before. This places higher requirements on the quality of every individual. The cultivation of innovative abilities and the improvement of overall quality are both inseparable from mathematics. To meet the demands of the new century for talent quality and to provide a training ground and stage for showcasing talents among math enthusiasts, we have collected and organized competition questions from junior high school mathematics across the country and various provinces and cities over the past decade. We have selected thought-provoking, innovative, and skillful questions that meet the requirements of ability and organized them into four parts: "Topic Analysis," "Basic Refinement," "Consolidation Training," and "Expansion and Improvement." This series of books is designed for extracurricular activities and after-school training for all grades of junior high school. Considering the needs for applicability and convenience, the series is organized on a daily basis, with each grade consisting of 26 lessons, each covering four days of training.
"Topic Analysis" provides a summary and review of the content of the lesson. "Basic Refinement" offers four examples that cover the key content and main methods and techniques of the lesson, along with four practice exercises for imitation. "Consolidation Training" provides four exercises that deepen and activate the content of the lesson from the perspective of thinking methods. "Expansion and Improvement" offers four typical problems that may involve knowledge beyond the lesson but can always be solved using the thinking methods covered in the lesson, demonstrating the comprehensive application of both knowledge and methods.
At the end of the book, there is an appendix with reference answers, providing detailed solutions for each problem. We aim to assist everyone in terms of thinking methods and innovative abilities, so more than half of the questions for each grade introduce thinking methods, highlighting the practical value of applying these methods in the knowledge sections.
