Features: As is well known, the junior high school stage is very important in one's life. If it goes well, getting into a key high school and going to university is not a problem; otherwise, it will be a different life. Therefore, it receives great attention and concern from students, parents, and schools. During this stage, junior high school teaching competitions play a very special role. The high-scoring questions and challenging problems in the junior high school entrance examination cannot be separated from it. There is a saying that "winning the competition means winning the entrance examination." Zhejiang is a major province in terms of teaching and education, and Zhuji Huanjiang Middle School is one of the top performers in junior high school teaching and subject achievements in Zhejiang. In the process of exploring and uncovering their effective methods, their success lies in creating a unique training method called "Rolling Training." This method is closely related to their classroom teaching; it is closely linked with starting from the first grade and being interconnected at every stage; it is closely related to the overall improvement of their entire teaching and research group. Introducing and promoting their training methods will benefit more teachers and students. The specific arrangement of "Rolling Training" is as follows: Each student has 12 teaching topics, with one training set for each topic, totaling 12 sets of topic training papers. Then, the rolling training begins sequentially: the content of the third topic rolls over, divided into "Rolling Training A Set" and "Rolling Training B Set." The "Rolling Training A Set" is deeper in content and more flexible in methods compared to the topic paper, while the "Rolling Training B Set" is even deeper and more flexible than the "Rolling Training A Set." After this in-depth and interconnected "rolling" of knowledge points, knowledge is consolidated, memory is strengthened, knowledge expansion is deepened, and techniques are integrated in the process, making progress both effortless and solid. Generally, we believe that mathematics competition is about solving difficult problems. If you isolate yourself and do the "Rolling Training B Set" alone, you may feel overwhelmed by the difficulty, as it is full of challenging problems. This made the authors recall the couplet on the "Spirit Spring Pavilion" between Hangzhou's Lingyin Temple and Feilai Peak: "Where does the wind fly from, when does the water cool?" Interpreting the Buddhist mystery is not easy. If we ask ourselves in a similar way, "Where does the difficulty of the questions arise from, and where does the flexibility of methods lie?" then the current "Rolling Training" series can provide you with the answers you seek. The principle is simple: the addition of a few simple questions can result in a very profound problem, and the combination of a few single ideas can lead to a more ingenious concept. After understanding the meaning of "rolling," it is not difficult to grasp the usage of this book. When studying a certain topic, you should then do the corresponding "Rolling Training A Set" and "Rolling Training B Set." In this way, the 12 topic training sets and two sets of rolling training papers, totaling 36 papers, will be rolled over over a year, and finally, 9 "pre-competition practical training papers" are arranged to test your year's gains. The fourth volume of this series is a comprehensive training after completing the entire junior high school, which is the "pre-competition practical simulation training" for junior high school teaching competitions. We hope that this "Rolling Training" series can help you achieve excellent results in the mathematics competition. Using a phrase from the field of physics: overcoming "sliding" is exhausting, while overcoming "rolling" is the most effortless.
