In the exam, many students will have such a situation. The teacher said this question, but he said it wrong, or the question changed a little. The number has changed, so I won't do it. This kind of situation, especially the students in the middle and lower reaches, appears the most. According to the above situation, the questions are generally brushed, why can't they be done? There are three reasons. Children lack the spirit of seeking truth. For a problem, after the child has done it, the child knows it whether he really knows it or not. His inner feelings are different from those of a fake meeting. After the real meeting, his heart stabilized. However, many children think that whether they like it or not, they should write it down and finish it. Children's understanding of knowledge is wrong. According to their own thinking, these students don't know what they did wrong, but think they did right. Lack of effective supervision and help. For various reasons, teachers or parents did not find the children's problems in time and did not give help. As a result, the mistakes were covered up until they failed the exam.

Mathematics learning methods are ever-changing, but in the end there are rules to follow. Among them, the foundation is eternal. Only by laying a solid foundation can we succeed in future study. Learning the basic concepts of mathematics well is one of the important ways to lay a good foundation for mathematics. Mathematical concepts include mathematical definitions, mathematical formulas, mathematical theorems and so on. Only by mastering the correct mathematical concepts can we understand the basic mathematical language, better understand the meaning of mathematics and deal with problems with mathematical thinking.

What kind of thinking mode can we learn math well without the problem of writing brush? First, intuitive thinking. I often ask some students a question. What comes to mind first? Students who can do it and students who can't answer the same question don't know how to think. So, what I can sum up is intuition. What is intuition? Intuition is the first time you see the knowledge points in the topic. Often give students a vulgar example. When you see a mobile phone on the ground, what is your intuition? The students all answered, pick it up. So this mobile phone is the knowledge point in the topic. The first reaction you see is to pick it up.

Instrumental thinking. When we can't finish some work, we use tools to help us finish it. The tools here refer to the knowledge points we find through intuition. Every important knowledge point will have its own figure in the textbook, including examples, definitions, properties, judgments and so on. These things are the function of this knowledge point and can help us solve this problem. Here, I usually give children a vulgar metaphor. What can I do to help you pass the ball when playing games? They all connected the equipment. The equipment here is a knowledge point. When we have a solid grasp of textbook knowledge and a thorough understanding, intuitive thinking and instrumental thinking will be gradually established, and you will find knowledge points and use them to do problems.
