1 on how to carry out extracurricular activities in middle school mathematics in China, extracurricular activities in middle school mathematics have been carried out for more than half a century. For example, in the 1920s, Suzhou Middle School set up a 18 research organization for mathematics, Chinese and English among students, and carried out activities regularly. In 1930s, there were more than 30 mass organizations in Beijing No.26 Middle School, including mathematics, sports, literature and art, academics and science and technology. Since the founding of the People's Republic of China, many primary and secondary schools have carried out extracurricular activities in mathematics and achieved good results and remarkable results. Many teachers have excavated and trained a group of outstanding mathematical talents through extracurricular activities in mathematics. Why do middle school students carry out extracurricular activities in mathematics? Because the goal of middle school mathematics education is mainly to let students master knowledge and improve their ability. However, in order to achieve the educational goal with high quality, it is not enough to complete the teaching progress only by relying on the usual classroom teaching. This is because the traditional classroom teaching has its own limitations: (1) In order to complete the teaching plan in a certain period of time, the traditional classroom teaching content is often too substantial, which is not conducive to giving full play to the enthusiasm and initiative of both teachers and students. (2) Although the traditional textbooks have been scrutinized repeatedly, they have formed a relatively complete theoretical system.
