First, learn to understand concepts and formulas.
Junior three students need to pay attention to the study of concepts and formulas, and their understanding of concepts can't stay on the surface of words, and they can't just memorize concepts and formulas. If there is a lack of connection with practical topics, it is impossible to connect the knowledge points learned with problem solving. Junior three students need to pay attention to the memory of mathematical formulas, which is the basis of understanding. If you can't memorize the formula, how can you skillfully use it in the topic?
According to the content of the textbook, we should compare and review what we have learned step by step, summarize concepts, theorems and formulas, deepen our understanding of knowledge, and strive to do the examples in the textbook by ourselves.
Second, do thorough math exercises.
Junior three students must form the habit of independent thinking after finishing their math homework. We should start with different methods and angles, explore a variety of problem-solving methods from typical topics, and get association and inspiration from them. For math problems, junior three students need to learn to ask more why, change conditions, add conditions, and exchange conditions for conclusions. Is the original conclusion still valid? Practice needs to be targeted, accurate, quick in answering questions and wide in thinking. You need to do problems when you study math, but don't brush them blindly. For some problems, you only need to make a list of solving ideas, knowledge points to be examined, key steps to solve problems and mathematical ideas used, so that you can consolidate basic knowledge, broaden your horizons and improve your problem-solving ability.
For the mistakes in homework and test papers, prepare a set of wrong questions so that similar mistakes will not happen again. I will classify the problems I have done and know what types of problems I can solve, what common problem-solving methods I have mastered and what types of problems I can't do. Some junior three students do repetitive work every day, and many similar problems are repeated, but they can't concentrate on solving the problems that need to be solved. Over time, the problems that can't be solved have not been solved, and the problems that can be solved have also been messed up because of the lack of overall grasp of mathematics. The purpose of practice is to practice the knowledge points and skills learned in practical topics, find out your own shortcomings and make up for them. Doing problems is like digging gold mines. Every wrong question is a gold mine. Only by digging and refining can we gain something.
Third, be good at raising and discussing problems.
Students in Grade Three have found problems they don't understand when studying mathematics, so they need to actively consult teachers, parents and classmates. "Building a car behind closed doors" will only make our problems more and more. Knowledge itself is coherent, the previous knowledge is unclear, and it will be more difficult to understand later. When these problems accumulate to a certain extent, we will gradually lose interest in learning.
Being good at asking and discussing questions is a very good way to learn mathematics. A difficult topic, after discussion with classmates, may get good inspiration and learn good methods and skills from each other.
Fourth, pay attention to the cultivation of examination skills.
Examination is a science. Some students usually get good grades. Teachers ask questions in class, and they can do anything. I can also do problems after class. But when it comes to the exam, the results are not ideal. What is the reason? It may be that the test mentality is not good and it is easy to be nervous; It may be that the examination schedule is unscientific, and it is always impossible to complete the paper within the specified time.
Every exam, junior three students should find appropriate adjustment methods and gradually adapt to the rhythm of the exam. Doing homework at ordinary times can limit time and gradually improve efficiency. In the exam, we should consider the completion time of each part to avoid unnecessary panic. Students in Grade Three need to treat exercises as exams and exams as exercises.
When learning mathematics, junior high school students need to find their own knowledge loopholes, practice repeatedly, think independently, analyze wrong questions and summarize mathematical methods and skills.
