First of all, teachers and children should understand the reasons for their poor grades, and then they can prescribe the right medicine. I teach math. The following is my opinion on how to improve my math scores. As a student, if you want to learn math well, you should first pay attention to the lectures in class. The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so we should pay attention to the learning efficiency in the classroom and seek correct learning methods. In class, you should keep up with the teacher's ideas, actively explore thinking, predict the next steps, and compare your own problem-solving ideas with what the teacher said. In particular, we should do a good job in learning basic knowledge and skills, and review them in time after class, leaving no doubt. First of all, before doing all kinds of exercises, you should recall the knowledge points that the teacher said, correctly master the reasoning process of various formulas, finish your homework independently and be diligent in thinking. For some problems that are difficult to solve for a while because of unclear thinking, we should calm down and seriously analyze the problems and try our best to solve them ourselves. Secondly, do more questions appropriately; If you want to learn mathematics well, you must do more problems and be familiar with the problem-solving ideas of various questions. At the beginning, we should start with the basic problems, take the exercises in the textbook as the standard, lay a good foundation repeatedly, and then find some extracurricular exercises to help broaden our thinking, improve our ability to analyze and solve problems, and master the general rules of solving problems. It is also necessary to mention that this is my experience in teaching mathematics for many years, that is, to learn mathematics well, we must pay attention to the understanding of concepts, and the context and function of theorems, definitions and formulas must be clear. You can't leave a dead end.

Don't worry, take your time. I wish your child good grades!
