1, pay attention to the foundation
The content of school textbooks has been strengthened, and mathematics is a subject with high requirements for understanding. The questions in the textbook should be done, and the exercises after class should not leave dead ends, so as to understand each topic.
Properly brush the questions, junior high school math problems have also changed to some extent. Brushing a certain amount of questions not only improves the speed but also deepens the understanding of knowledge points.
Attach importance to the training of geometric proof. Although geometry proof is weakened in senior high school, it plays a great role in improving students' logical thinking ability in junior high school, which is of great significance to improving students' analytical ability and is also a good preparation for senior high school study.
2. Strengthen training
Appropriate deepening can improve students' ability to use knowledge. Students who have spare time to study at ordinary times can ponder more difficult topics, develop good thinking habits and improve their ability to solve problems. There is also the need to deepen the function, which is also the focus and difficulty of the senior high school entrance examination, so as to effectively pass the senior high school entrance examination.
In addition, the investigation of junior high school mathematics content is too simple, so that many students can not adapt to senior high school; First, knowledge points and difficulty are not at the same level, such as factorization. Junior high school may require simple requirements, but senior high school is completely different.
The characteristics of mathematics:
1, highly abstract
The content of mathematics is very abstract, but it only describes the objective reality from the aspects of quantitative relationship, spatial form or general structure, and abandons all other irrelevant properties, showing the characteristics of high abstraction.
2. Rigorous logic
The basic research object of mathematics is to artificially define old mathematical concepts. They are formal ideological materials, which can be tested by repeated experiments, observations or measurements, but they are mainly proved by strict logical reasoning. Once the conclusion is proved by reasoning, then this conclusion is correct.
3. Universality of application
As we all know, in people's daily life, work, productive labor and scientific research, mathematical knowledge is used in all disciplines of natural science. With the rapid development of modern science and technology, mathematics has become an indispensable tool.
