The basic concepts, definitions and formulas of mathematics, the internal relations between mathematical knowledge points, and the basic ideas and methods of solving mathematical problems are the most important things in review. To return to the textbook, we must first sort out the knowledge points and do every example and exercise in the textbook to ensure that the basic concepts and formulas are firmly mastered. Slow and steady, don't climb blindly, haste makes waste. There are many contents in the review class, and time is tight. In order to improve the review efficiency, we must synchronize our thoughts with the teachers'. Preview is an important way to achieve this goal. Without preview, listening to the teacher will make you feel that everything the teacher says is very important and you can't grasp the key points of the teacher's speech; After previewing, listen to the teacher's lecture. You will choose what the teacher has said in your memory and focus on what you have not mastered to improve your learning efficiency.

Second, improve the efficiency of classroom lectures, use more brains and work hard.

There are only two forms of class in grade three: review class and class evaluation. By the third day, all classes have entered the review stage. Through review, students should know which knowledge points they have mastered better and which knowledge points need to be improved. Therefore, they must have their own thinking before reviewing the class, so that the purpose of the class is clear. Now students will have some review materials in their hands. They should do the example again before the teacher gives a lecture. The difficulty found in doing the problem is the focus of the lecture. For the old knowledge that is not well mastered in the preview, we can check and fill in the gaps, thus reducing the difficulties in the course of listening to lectures. By comparing and analyzing what you understand with the teacher's explanation, you can improve your mathematical thinking. Experience the thinking of analyzing problems and the thinking method of solving problems. If you persist, you will be able to draw inferences and get twice the result with half the effort. In addition, it is very important to take notes on the difficulties of teachers' lectures. Notes are not records, but simple and concise records of the main points and thinking methods in the above lectures for review, digestion and thinking.

Third, establish a wrong book to check for missing items.

In the third grade review, dozens or even hundreds of sets of various test questions should be done. Special-grade teachers of People's Education and Learning Network remind students to set up a wrong problem book, sort out the problems they usually make, write comments and reasons for doing mistakes on it, and take out the "wrong problem book" every once in a while. When reading reference books, you can also target the key or wrong questions, and then focus on this book in the future. The process of checking and filling gaps is the process of reflection. In addition to understanding different problems, we should also learn to "draw inferences from others" and summarize them in time. Every time you revise a test paper or homework, write down the reasons for doing it wrong next to the wrong questions.
