First, the importance of reviewing questions "How can students be wrong when faced with questions that have been done several times, told several times and emphasized several times?" Everyone is too familiar with such complaints! Now you can calm down and think about whose fault it is. When you ask students to do the problem carefully, they are still wrong. What is the reason? When you ask a student to correct his mistake, he will do it right even if you don't tell him. What is the reason? I just didn't carefully examine the questions. Therefore, in the process of primary school students' mathematics learning, the examination of questions is a very important link throughout the whole learning process. No matter what problem is solved, it is inseparable from the examination. It can be said that the examination of questions is the basis of solving problems.

Second, what is an exam?

1. Examination is to see clearly and understand the meaning.

2. Examining questions is an important process between students seeing problems and writing to solve them. There is a very important process between students seeing problems and writing to solve them, which is the examination of questions. Examination of questions is a kind of ability to obtain information, analyze information and process information. It needs to be based on a certain level of knowledge, as well as good reading habits and effective thinking methods. This ability is not achieved overnight and needs to be learned.

3. Examination of questions is the process of students' digging and transmitting information. Examination of questions is a process of mining and transmitting information. It is a process of extracting, combining, processing and expressing the information contained in the problem. Only through careful observation and grasping key information can we understand the essence of the problem and choose reasonable methods to solve it. We often find that many children have a very bad habit, that is, they like to add, subtract, multiply and divide when they get questions and see numbers. Some teachers joked with some students that this is a battle of addition, subtraction, multiplication and division, and whoever wins will use it. For some simple questions, this may not be a problem, but for those who like to "turn", they will find problems. For example, an exercise like this: "Three teachers lead 82 students. Many students seem to forget the existence of "three" because they only saw the Arabic numerals 82 and 2, so they didn't count three teachers.
