2, the teacher will be a chapter before, be sure to preview, draw the concept, first recite the formula, there are examples in the book, don't look at the examples of how to solve, cover up the answers, do it yourself, and then compare your own answers with the examples. From the perspective of thinking, what is the method, and then compare which method is easier and which is more acceptable. Remember: the answer in the book is not.
3. Ask the teacher if you don't understand. In fact, teachers like students who often ask questions. Don't think your problem is simple, but you can't do it yourself. Just stay there and solve it in time! It is a good thing to have problems, and the biggest problem is that there is no problem.
4. There is no shortcut to learn mathematics well, only to do problems, and to be able to endure hardships, such as doing 1-2 fill-in-the-blank questions during recess, and doing big questions at home or during self-study at night, because the time between recess is short and it is more convenient to fill-in-the-blank questions. This fourth method is also taught by senior three students. When doing the problem, you must suit yourself. Don't do the difficult problem at once, take your time.
5, wrong problem set, don't be afraid of trouble, wrong problem set is very important, you must sort out the wrong questions in exams and exercises, don't just read them once, it's useless, put them in a thick notebook, copy them down, leave a few lines blank, then write the answer to that question in some places at the top of the notebook, do that question in a few weeks, and then see you do it again.
In fact, I was poor at math in junior high school, but after I went to high school, I did some methods by myself according to the above five points, and my math scores gradually improved.
