1 How to learn primary school mathematics well
Compare and master the essence of concepts
In mathematics, some concepts and knowledge are similar or similar, which are easy to be confused and difficult to master, which makes it difficult for students to learn. Comparison is to confirm the same or different items. By comparison, we can better grasp the essence of knowledge and concepts, so as to better grasp concepts and knowledge.
There is a unit called "perimeter" in the first volume of the third grade mathematics of Beijing Normal University, and the unit of "area" is learned in the second volume of the third grade. The knowledge of these two units is easily confused by students, so by comparing the concepts, calculation methods and unit names of "perimeter" and "area", we can grasp the essence of the concepts. Therefore, grasping the essence is also an important and effective way to learn mathematics. Students have learned the "comparative" learning method, and can consciously use it when learning similar concepts, so as to better master knowledge.
Through classification, we can deeply understand knowledge.
Classification is a way of thinking based on comparison. According to the similarities and differences of things, objects with the same nature are classified into the same category. Classification should have standards, and the results of different standards will be different. Classification is an important way of thinking to learn mathematical concepts and help students understand knowledge.
When I was studying triangles, I gave some triangles to students to classify. Some students divide these triangles into three categories according to their angles: the first category is that all three angles are acute; The second is that one angle is obtuse and the other two angles are acute; The third is that one angle is a right angle and the other two angles are acute angles. Through this classification, students have mastered the concepts of acute triangle, obtuse triangle and right triangle. Some students divide these triangles into three categories according to their sides: the first category is that all three sides are equal; The second category is equality on both sides; The third category is that all three parties are unequal. Through this classification, students master the concepts of equilateral triangle and isosceles triangle, and understand the relationship between equilateral triangle and isosceles triangle.
2 How to make students learn math well
Make a series of personal mistakes. I give my classmates a formula: less mistakes = more pairs. If you make a mistake, no matter what mistakes you find, no matter how simple they are, they are included; I believe that once you really do it, you will be surprised to find that your mistakes can't be corrected once. On the contrary, many mistakes are made for the second, third or even more times! Looking at my wrong suit, alas, it's shocking. This is really a good place for self-reflection and a good way to improve your grades. The later you review, the less likely you are to break through knowledge, and the room for correcting mistakes is not small. If you don't have this habit, prepare one, collect your mistakes, classify them, and then turn them over when you have nothing to do, have a look and warn yourself, and you will certainly gain a lot.
What should I do if I encounter difficulties? First of all, we should try our best to solve it through our own efforts. If it can't be solved, we should also find out why it won't and where the problem lies. I often say: never expect not to encounter problems, but never allow yourself not to understand where the problems are. When you can't solve it by yourself, you can solve those problems by discussing and asking the teacher. The solution is by no means that you can't do it with the help of others, but after doing it, look back and compare the reasons why you can't do it, and be sure to find out the reasons. Otherwise, you will lose an opportunity to improve and lose the meaning of doing the problem.
A reference book is enough. I want to say, don't be superstitious about reference books. There are not many reference books, but one main one is enough. I found a very strange phenomenon. Nowadays, many reference books on the market sell well, all of which are branded by a famous teacher. How well they speak. As a result, many students took one book after another, confused. In fact, our time for study and review is limited, and the time we can leave for ourselves is even more limited. In these limited time, it's best not to read this reference book for a while and that reference book for a while. By memorizing the main points of the knowledge structure of the textbook, you can review all the knowledge in a short time. Doing this is much more important than reading some reference books called "Golden Keys and Silver Keys". In a word, grasp the most fundamental and important, don't read reference books blindly, especially don't read many reference books. I don't know, it will be more difficult to understand after learning. When these problems accumulate to a certain extent, you will gradually lose interest in the subject. Until I can't keep up.
3 How do primary school students learn math well
Establish a good atmosphere, create a good atmosphere, and cultivate students' good habit of listening carefully.
After the new curriculum reform, children suddenly become active and courageous. Students dare to ask questions and express their views and opinions. Therefore, we should first cultivate students' good habits of listening carefully, speaking boldly and thinking seriously. Sometimes in class, the teacher is talking with relish, and some students are doing their own things like playing with pens, whispering, handing notes and making up homework, which is not interesting. Cultivating students' listening ability and quality has always been the essence of our education, and educators at all times and all over the world are emphasizing the importance of' listening' in study and life. A lot of knowledge is learned by watching or listening to others.
In math class, it is not enough for students to have book knowledge. It is a good habit to listen to other people's opinions. Only by listening to the teacher's lectures and students' speeches can we actively participate in teaching activities, open the spark of wisdom to acquire knowledge and cultivate ability, and ensure the effective classroom. Therefore, in teaching, we must have a clear goal. When moving, we should concentrate on understanding the teacher's explanation, pay attention to the students' speeches, develop good listening habits and listen carefully. It will greatly promote the improvement of people's overall quality, and you can express your sincere opinions at an appropriate time. Of course, listening carefully is also a good moral character of respecting others and doing things sincerely.
Develop a good habit of learning consciously and actively.
Teaching is an art, teachers should be flexible and keep fresh, so as to stimulate students' interest in learning and let students actively participate in learning. In teaching, the teaching content should be varied and flexible according to the characteristics of students, so that each class has new ideas and freshness, so that students' attention can be absorbed in the classroom and their brains can think positively.
For example, when learning the area of parallelogram, triangle and trapezoid, the basic method is to convert the newly learned graphics into the learned graphics by cutting and spelling. According to the active characteristics of students, I specially arrange and guide students to cut and spell, and observe the relationship between the cut and spell graphics and the original graphics in combination with textbooks. In this way, you can get twice the result with half the effort when learning the above three formulas. By analogy, it is easy to learn the area calculation of these geometric figures. This "hands-on" learning method attracts students' various senses to participate in learning and greatly stimulates students' interest. Gradually develop the habit of students solving practical problems through their own reading. When encountering difficulties, most students can actively think of ways, make gestures, discuss with classmates and teachers, and solve them by themselves, thus forming the pleasure of overcoming difficulties and achieving success in learning, and learning consciously and actively.
4 How to learn primary school mathematics well
Mathematics is a very rigorous subject. If we miss a decimal point, we won't get the correct answer. Some children are careless and often miscalculate their grades. Imagining out of thin air is a bad study habit. Learning mathematics requires a high degree of concentration. Students should be immersed in the joy of learning, whether in learning or in the process of solving problems, and don't expect to solve problems quickly and easily. In fact, it is through this long and slow exploration that we truly realize the magic and greatness of natural science. When students concentrate on their studies, our teachers and parents must not disturb them, because this is the process that everyone must go through if they want to learn knowledge and finally think independently. We should create more time for independent thinking so that children can develop good study habits.
Independent thinking is very important for our study. Only by truly understanding and even deducing the theorem can we truly master and learn. Some students are curious to explore knowledge, whether it is the knowledge in textbooks or the kilometer theorem taught by teachers, they have to verify it for a while. It can be seen that they are ecstatic after a long period of successful verification. I know this is their happy learner, and some students can prove a problem in a month. We like this learning state very much. Students are really thinking and solving problems with their own knowledge when doing problems. Just because we remember a certain principle does not mean that we have learned it, nor does it mean that we can really apply it after we understand it. Even if we use the newly learned principles in class, we may not be able to do it ourselves after class. Learning doesn't mean you can use it. This phenomenon is very common. There are many children with strong learning ability and not many children with strong application ability. This requires us to do more exercises and do more problems. Only by doing problems can we really understand and learn knowledge. Teachers must not discourage students from studying, and don't be sarcastic. Even if students ask simple questions, we should answer them seriously. Don't let students leave knowledge blind spots.
In the teaching process, we all combine simple and common life phenomena in real life, which can improve students' interest in learning and make complex and abstract mathematical knowledge easy to understand. In our teaching process, we will find that each student's situation is different and the problems are different. We should adopt different attitudes and methods to face students. Students are actually very sensitive. We must take good care of their emotions and self-esteem. Our casual glance may offend them. If we annoy students, it will be difficult for them to learn our lessons well. Some children have good thinking ability, but they can think independently, but their concentration is not good. We should guide them correctly. Most of these students are boys, and each of them has different learning purposes. Don't think that children like learning and love knowledge and science, which is far from children. Children may start learning just to please their parents' praise or just to have more face in front of others, no matter what their mentality and purpose, as long as they can study hard. I believe that mathematics is very attractive, and many students will fall in love with him slowly, and eventually they will study because they like mathematics.
