A few days ago, the teaching series of Tianjin Bao Jing Institute of Continuing Education has come out with new works. The anthology "One Problem with Many Solutions" edited by Lu, a senior math teacher in Tianjin No.1 Middle School, will be reprinted in the near future. In addition to the free distribution to junior students who participated in the "Journey" student aid activities, Bao Jing University has expanded the printing scale, and junior students in the city can receive it free of charge at the two campuses of Bao Jing Institute of Continuing Education at the end of 10.

The book contains "Mathematicians learn geometry" and "Fourteen solutions to a middle school exam". "Have you thought of these solutions?" There are five units: "More benefits and more fun to solve a problem" and "Learning to solve ladder problems". In addition, Mr. Lu compiled the Sixteen Proof Methods of Geometric Theorem by the mathematician master in this manual, which reproduced the master's geometric thought. The author of this book, Mr. Lu, has been engaged in junior high school mathematics teaching for more than 40 years. Skilled in business and experienced in education and teaching, especially in plane geometry. It has played an important role in the teaching and research of plane geometry in Tianjin, and has been well received by students and parents and recognized by the society. Participated in teaching material analysis, training of young teachers, continuing education of teachers and training of Olympic coaches. He has a high prestige among his peers in Tianjin and is known as the "King of Geometry".

According to Teacher Lu, if students want to improve their problem-solving ability and learning efficiency, they must learn to practice multiple solutions to one problem, that is, to solve the same problem in various ways. This is a common training method in scientific practice. This method can not only master and apply the learned knowledge more firmly. Moreover, through the analysis and comparison, we can find ways and methods to solve problems and cultivate our creative thinking ability. Appropriately adding some exercises with multiple solutions to one problem is of great benefit to consolidating knowledge, enhancing problem-solving ability and improving academic performance. Geometric problems can usually be solved in many ways. When you prove the same problem in different ways, your divergent thinking ability will naturally be exercised, and your comprehensive application of knowledge will be improved accordingly. At the same time, you can feel the infinite mystery of the mathematical world.

It is reported that this book is based on the first edition of "One Question with Many Solutions", and has been integrated and improved according to the adjustment of teaching syllabus, the arrangement of teaching progress and the characteristics of mathematics test questions in the 2007 senior high school entrance examination. I believe it will definitely set off a book buying craze again.
