We must tell students the importance of math notes, do a good job in this work, embody math ideas and methods, show thinking in thinking, and expose where the problems are concentrated in the process of doing problems, so as to find mistakes and catch up. Therefore, in order to avoid being covered by "sea tactics" in future math learning and achieve twice the result with half the effort, we must make good math notes and stick to them seriously.
Second, remember: never turn a math notebook into a draft.
In the actual class, the math teacher always emphasizes that the draft book must be prepared in the math class, and calculus and reasoning should be carried out at any time. But it is this simple requirement that there will always be more than a dozen people in the class, but there is no draft book. What should I do if I want to do mathematical calculus reasoning? Don't worry, isn't there a thick notebook next to it? It doesn't matter if you use one first. Over time, except the draft book, where is the notebook? Imagine: how many people can cherish their draft books?
Third, math notes can't be used as a running account.
In math class, there are also such students-no matter what the math teacher writes on the blackboard, they recite it very seriously, giving people a very serious feeling. But is it necessary to do so? Can you reflect the difficulties, knowledge structure and relationship of mathematics knowledge in your notes? As expected, these students can't answer the above questions.
So when taking math notes, don't rely too much on notes, write them down as a running account, and ignore the important listening and understanding in math class. As long as these foundations are established, math notes will be useful.
