Read the text and understand the main content.

Mathematics course is the basis of learning mathematics. Read it word for word, don't skim it. We should look for mathematical information from the situation diagram of the textbook, understand new knowledge as a whole, read the conclusions in the book, and mark important concepts and conclusions. If you are not impressed by reading it once, you can read it again carefully, gradually master the ins and outs of knowledge, understand the problem-solving ideas and screenshot methods of examples, and then listen carefully in class to digest and absorb this knowledge. This is the main link of math preview.

Think carefully and mark the doubts.

Mathematics preview is different from Chinese preview. Only by writing more and practicing more can we achieve the effect. Mathematics preview should pay attention to methods, not rote learning, pay attention to understanding, find out the ins and outs, and try to understand knowledge through your own thinking and analysis. Think about the examples in the book and see if there are any other solutions. Preview is not equal to self-study. You can think about the difficulties you encountered in the preview first. If you really can't understand or solve it, you can mark it in time and leave it to the teacher to explain in class for understanding.

Try to do after-class exercises to test the effect of preview.

Through preview, I have initially understood and mastered new mathematics knowledge, and I can test the preview effect by doing exercises after class. Through practice, we can not only find our own shortcomings, deepen our impression and consolidate our knowledge, but also make clear the key points and difficulties of teachers' lectures. This is an indispensable part of math preview.
