First, preview before class
In order to learn junior high school mathematics well, it is necessary to preview before class. Many children don't have the habit of previewing in advance, and they don't agree with it, but previewing is a very important habit, which will directly affect children's mathematics classroom learning effect.
By previewing before class, children can know in advance what the teacher will say in this class. First of all, they have a general impression. In class, they can also keep up with the teacher's ideas and rhythm, take the initiative to attend classes, and have enough time to think. Students who don't preview only passively accept what the teacher says, and the learning effect is inevitably not as good as that of children who preview actively.
Second, pay attention to the study of basic knowledge.
Junior one children's math scores will be very poor, mainly because the knowledge and knowledge structure of basic test sites in math textbooks are not solid, and they are not skilled in mastering basic questions and formulas, which leads to their lack of basic thinking and logical reasoning ability in math subjects and poor application ability of basic test sites.
In the process of learning, children should first be familiar with the contents of math textbooks, memorize important formulas, theorems and important examples in each chapter of the textbooks, and must lay a good foundation to remedy the problem of poor math performance. Laying a good foundation is also a good foundation for further study. Only with a solid foundation can we learn more difficult knowledge without worry.
Third, look at some examples.
Careful classmates will find that after explaining the basic content, teachers will always supplement some extracurricular examples and exercises, which is of great benefit. The concepts and theorems that children learn are generally abstract. In order to make them concrete, they need to be applied to the theme. Because children have just come into contact with this knowledge, they are not skilled enough to use it. At this time, examples can be of great help.
Children can concretize the existing concepts in their minds by looking at examples, thus making their understanding of knowledge more profound and thorough. Because the examples added by the teacher are very limited, we should learn to find one more example after class.
Fourth, insist on correcting the wrong questions.
Grade seven students can bind the whole semester's papers together, spend half a day correcting the wrong questions every week, mark them with asterisks, and ask teachers and classmates until they know. Continue to correct it next week to see if you really understand it. For the wrong question, just like a camel eating grass, it keeps chewing.
Wrong questions also require children to think repeatedly to avoid repeating mistakes in the same type of questions during the exam.
Five, collect your typical mistakes and questions that you can't.
The most difficult thing for students is their own mistakes and difficulties. But this is precisely the problem that needs to be solved most. There are two important purposes for students to do problems: to practice their knowledge and skills in practical problems. Find out your own shortcomings and make up for them.
