(3) If you master the multiplication formula of 2, 3 and 4, you can use the formula you have learned to perform multiplication and solve simple practical problems.
Math learning methods in grade two
First, the correct primary school mathematics learning methods-seize the classroom
Science study focuses on weekdays and is not suitable for surprise review. The most important thing to study on weekdays is to attend class for 45 minutes. Listen attentively and keep your thoughts close to the teacher. At the same time, it should be pointed out that many students tend to ignore the mathematical thinking methods taught by teachers and pay attention to the solution of problems. In fact, thinking methods such as "transformation" and "combination of numbers and shapes" are far more important than the solution of a problem.
Second, finish the homework with high quality.
The so-called high quality refers to high precision and high speed. When writing homework, I sometimes repeat the same type of questions. At this time, we should consciously examine the speed and accuracy, and we can have a deeper thinking about this kind of problem every time we finish it, such as the content it examines, the mathematical thinking method used, the rules and skills of solving problems, etc. In addition, the thinking questions assigned by the teacher should also be carefully completed. If you don't give up easily, you must carry forward the spirit of "nails" and think quietly whenever you have time. Inspiration always pops up in front of you. Most importantly, this is an opportunity to challenge yourself. What are the methods of learning mathematics in primary schools? Success will bring self-confidence, which is very important for learning science; Even if you fail, this question will leave a deep impression on you.
Third, think hard and ask more questions.
First of all, for the laws and theorems given by teachers, we should not only know "what it is", but also know "why it is like this". There are also some things we don't understand about the correct learning method of primary school mathematics, so we should get to the bottom of it. This is the way to understand. Secondly, we should be skeptical about learning any subject, especially science. If you have any questions about the teacher's explanation and the content of the textbook, please feel free to ask questions and discuss with the teacher. In a word, thinking and asking questions are the ways to eliminate hidden dangers in learning.
Fourth, sum up and contrast, and clear up ideas.
(1) summary and comparison of knowledge points. After learning each chapter, you should make a frame diagram of the content of this chapter or go through it in your mind to clarify the relationship between them. Similar and confusing knowledge points should be summarized and compared separately, and sometimes they can be distinguished by association.
(2) Summary and comparison of topics. Students can set up their own question bank. I have two sets of problem sets. One is wrong and the other is accurate. Write down the mistakes in the usual homework and exams selectively, and mark the matters needing attention with a red pen on one side. Just read what is written in red pen before the exam. I also wrote down some extremely clever or difficult problems I saw, and marked the methods used in this problem and the methods of mathematics learning in ideological primary school in red. After a long time, I can sum up some types of problem-solving rules and write them down in red notes. In the end, they will become your precious wealth and be of great help to your math study.
Fifth, do extracurricular exercises selectively.
Spare time is very precious to us middle school students, so when you do extracurricular exercises, you should be less and better. As long as you do two or three questions every day, your mind will be broadened after a long time.
The correct method of primary school mathematics learning is important, but the spirit of perseverance and Excellence is more important. As long as you work hard, you will learn math well. Believe in yourself, math will make your wisdom shine more!
