2. After the knowledge points are classified into good categories, the big knowledge points are subdivided into several small knowledge points, such as 1. The meaning and representation of sets II. The basic relationship between sets. After this subdivision, I began to formally summarize my notes one by one! First of all, we need the focus of the macro scanning section, which can be eliminated and which must be recorded, and we need to grasp it according to our own learning level. Generally speaking, we should focus on the summary of the book. Especially the sentences marked in other colors in the book, you must copy them, because these sentences are generally definitions. Only by mastering the meaning of this knowledge point can we better understand and help with the problem!
3. The most important thing in math notes is to master the basic problem-solving methods, and the remaining advanced problems need to be self-expanded. The most direct method of teaching materials is to integrate the basic steps of doing problems into examples. Therefore, while copying the examples in each section, don't forget to look carefully at the steps of doing the questions, and also master the rules of doing the questions. It is better to really learn to "do" the questions, then copy them into the notebook, do them again by yourself, and then correct them with a red pen against the textbook.
4. In addition to the above, there is also the role of a pen. As the name implies, the function of the scribing pen is to scribble important keywords or a very important theorem. Scribing needs to be appropriate, just cross out the important parts. Don't mistakenly think that the scribing should be all over the floor, and make the whole notebook colorful. If you can't find the key points before the exam, then the role of the notebook will be greatly reduced.
The notes we take don't need to be beautiful and neat, but we need to understand them ourselves. Therefore, we can use post-it notes with confidence, and write the knowledge points and precautions added by the teacher in class on the post-it notes at any time to supplement our notes. Therefore, it is not necessary to fill your notebook at ordinary times, and you can also leave some blanks for post-it notes to supplement and improve your notes at any time.
6. Last but not least. That is, there are exercises in this section at the end of each section of the textbook. Although there are not many topics, they are really fine. It takes a lot of time to organize notebooks, not to mention the whole high school books. Such a small exercise can not only test your level, but also save you time. Why not?
