The external things are mathematics.
The first thing to mention is how to avoid poor academic performance caused by inattention in class. In fact, many people can't concentrate for 40 minutes, and it is almost impossible to emphasize that 40 minutes of class is not absent-minded. If you can do it: "first, preview before class and write down what you don't understand;" Second, in class, the teacher listens carefully where he doesn't understand; Third, in case you miss the key points because of desertion, review carefully after class and then write down what you don't understand; Fourth, the teacher will talk about what he doesn't understand and focus on listening. "This repeated cycle can effectively avoid the problem of poor learning effect caused by inattention in class.

There is no end to learning, but there are ways. Good learning methods can help children get ahead of others quickly, which is a shortcut.

Special emphasis is placed on the foundation. To lay a good foundation is to thoroughly understand textbooks, which are the crystallization of human collective wisdom. If you can skillfully answer the main points of knowledge even if you wake up in the middle of the night, your academic performance will be excellent.

English: First of all, written language. It is a shame for a person who doesn't know the written language of his own nation. Secondly, what is grammar? Talking with people who use the same language, regardless of grammar, can understand each other and not hinder communication. How come... This is actually that people who use the same language unconsciously follow certain rules in the process of communication. Smart people summarize and sort out these rules and become grammar. When many children are studying, they are often most afraid of failing the exam, and they are most afraid of failing the exam. That's because Chinese learning depends on the usual accumulation, unlike mathematics, physics and chemistry, which are easy to make up. Special emphasis is placed on reading aloud, because reading aloud can help children understand the artistic conception of an article or a poem (whether or not they understand the author's true meaning at that time) and enhance their imagination. How to learn Chinese well? Good results can be achieved by reading aloud, remembering words and meanings, and mastering grammar.

How to write a good composition? I am afraid to write a composition because the author thinks there is no material. There is no matter because no matter is found. In fact, life is beautiful, as long as you love more. This is a commonplace question. The hardest part is actually in the beginning Many children don't know how to start writing a composition. In fact, just tell them the truth: writing a composition is to write a true story and write your own true feelings. Protagonists in world famous works can find prototypes in real life, let alone children's compositions. It is impossible for children to write a good composition by imagination and fabrication. For example, if a child's parents quarrel, show the child that the quarrel is real and the child's feelings are real, then the child will have so-called material to write and something to write. "Wash your dirty linen in public", some children will ask: "Mom and Dad quarreled, let other students know, won't they laugh at me?" Tell him: "You can describe things, real people, real inner feelings. Just write the quarrel between mom and dad as an uncle and aunt quarrel! "

Foreign language: a foreign language is also a kind of Chinese, which has many similarities with Chinese. The difference between a foreign language and Chinese is that there is no language environment. If we can consciously create a language environment for a foreign language and refer to Chinese learning methods, we will certainly learn well.

Mathematics: Focus on understanding concepts. The concept of understanding belongs to the category of Chinese. If you can't understand the concept, then when the teacher lectures, the child is just like listening to a gobbledygook and doesn't know what to say. Of course, he can't learn well. If you can understand or remember mathematical concepts (you can't really understand them yet, so don't imitate them by rote), then when the teacher lectures, use your brain to think about why the teacher did it, what methods and theorems were used, where to cut in, and use what the teacher said to verify the basic concepts you understand or remember, which in turn will deepen your understanding and memory of the basic concepts, which will have a better effect of drawing inferences from others. Mathematics will be sharp if you do appropriate targeted exercises on the basis of understanding concepts. Mathematics is most afraid of being right, and I don't know where it is; I'd rather do something wrong and know where it is. To learn mathematics well, you don't have to do a lot of problems, and you should oppose the tactics of asking questions.
