1, learn to preview actively. Before explaining new knowledge, it is an important means to read the teaching materials carefully and develop the habit of previewing actively. Therefore, cultivate self-study ability, learn to read books under the guidance of teachers, and preview with teachers' carefully designed thinking problems. For example, if you teach yourself an example, you should find out what the example is about, what the conditions are, what you want, how to answer it in the book, why you answer it like this, whether there is a new solution and what the steps are. Grasp these important problems, think with your head, go deep step by step, and learn to use existing knowledge to explore new knowledge independently.

2. Grasp the classroom. Science is mainly based on general study and is not suitable for surprise review. In every class the teacher tells us, we should concentrate, listen carefully and follow the teacher's ideas closely. Listen more and remember the math ideas and learning methods the teacher said. Don't be limited by a certain problem. For example, thinking methods such as "reduction thinking" and "combination of numbers and shapes" are far more important than the solution of a topic.

3. Think hard and ask more questions. First of all, we should not only "know why" but also "know why" the laws and theorems given by teachers. When you don't know how to study, you should get to the bottom of it. Secondly, you should be skeptical about learning any subject, especially science. Ask questions about the teacher's explanation and the content of the textbook at any time and discuss with the teacher. Don't pile up problems, finish what you do on the same day. In short, thinking and asking questions are the best ways to eliminate hidden dangers in learning.

4. Complete 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 deeper thinking on such problems every time we finish. Such as investigating its content, using mathematical thinking methods, solving problems and skills. 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", think quietly whenever you have time, and inspiration will always come to you inadvertently. More importantly, this is an opportunity to challenge yourself.
