First, return to textbooks, lay a solid foundation and make good preparations.
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'. 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. Students can set up a mistake book, sort out the mistakes they usually make, write comments and reasons for making mistakes on it, and take out the "mistake notes" 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.
Fourth, grasp the key points, highlight the key points, and don't talk about heroes by the amount of questions.
It takes a lot of problems to learn math well, but doing a lot of problems in turn is not necessarily good at math. Questioning tactics sometimes get twice the result with half the effort, so it is necessary to improve the efficiency of solving problems. The purpose of doing the problem is to check whether you have mastered the knowledge and methods well. If you are not accurate or even biased, the result of doing so many questions will consolidate your shortcomings. It is necessary to do a certain amount of exercises on the basis of accurately mastering the basic knowledge and methods, but you should do the questions in a targeted manner, highlight the key points and grasp the key points. In review, the so-called highlighting the key points mainly refers to highlighting the key knowledge in the textbook, highlighting the knowledge that is difficult to understand or has not been deeply understood, and highlighting mathematical ideas and problem-solving methods.
Fifth, we should develop good problem-solving habits.
For example, some students (especially those with good brains) look at the questions carefully, see the figures clearly, standardize the problem-solving format, and feel very good about themselves. Usually just write the answer to a question, without paying attention to the problem-solving process, and the writing is not standardized. Even if the answer is correct in the formal exam, they will be deducted more points because of the incomplete process. Some students usually lack self-confidence in the learning process, so it is inevitable to check each other's answers when doing homework, and they have not carefully found out the reasons for the mistakes and corrected them. These students often make psychological mistakes when they arrive at the examination room, which leads to "meeting without being right", or in order to ensure the correct rate, they repeatedly check and calculate, wasting a lot of time and affecting the overall performance. These problems are difficult to solve in a short time and must be corrected in peacetime. "Meeting without being right" is a taboo in math learning in grade three. There are common mistakes in exams and calculations, which are usually considered to be carelessness. In fact, this is a bad study habit, which must be gradually overcome in the first round of review. Otherwise, there will be endless trouble.
