Operation is the basic skill to learn mathematics well.
Junior high school is the golden age to cultivate mathematical operation ability. The main contents of junior high school algebra are related to operations, such as the operation of mathematical numbers, the operation of algebraic expressions, factorization, fractional operation, radical operation and solving equations in junior high school. The poor operation ability of junior middle school will directly affect the later mathematics study.
Attach importance to consolidating the double foundation of mathematics
To lay a solid foundation of mathematics in the review process, we should pay attention to the deepening of knowledge and strengthen the training of exercise groups-understanding mathematical thinking methods.
In addition to doing basic training questions and plane geometry once a day, you can also do some comprehensive questions to develop the habit of reflection after solving problems. Reflect on your own thinking process, knowledge points and problem-solving skills, the advantages and disadvantages of various solutions, and the vertical and horizontal relations of various methods. And summed up the mathematical thinking methods it used, grouped the topics with similar thinking methods into a group, and constantly refined and deepened them, so as to draw inferences from others. Gradually learn to observe, experiment, analyze, guess, induce, analogy, association and other ways of thinking, and actively find and ask questions.
Basic knowledge is very important
To improve math scores, we must have a solid basic knowledge of math as a starting point, because many math questions are a test of the ability to integrate basic knowledge. Only on the basis of solid basic knowledge points can we improve our ability to integrate knowledge. There is only one month before the senior high school entrance examination, so it is impossible to learn the basic knowledge of mathematics. Therefore, we must check and fill the gaps according to the test sites of the senior high school entrance examination and our existing knowledge, so as to maximize the learning effect.
Attach importance to common formula skills
To understand the ins and outs of commonly used mathematical formulas, it is necessary to further understand their reasoning process and explore some possible changes in the process of derivation. Necessary training should also be given to the knowledge and skills necessary for further study and common sense often used in daily life. For example, the square of 1-20; Simple Pythagorean number; The area formula of regular triangle and the relationship between height and side length; The relationship between the three sides of a 30-degree and 45-degree right triangle ... This will definitely help you master the formula better than doing a lot of exercises, and it will often have unexpected effects.
The above are the knowledge points of junior high school mathematics that I have compiled for you: How to improve junior high school mathematics scores quickly?
