Expanding reading: the learning method of primary school mathematics

1, not only to listen to lectures, but also to think.

Many students can listen carefully in class and have a deep memory of basic knowledge such as formulas and concepts, but they can't do it when they encounter practical problems. Therefore, students should not only listen carefully in class, follow the teacher's ideas, but also think and understand the problem-solving ideas. For mathematics learning, the most important thing is the cultivation of problem-solving ability and knowledge application ability. If a student only remembers the basic knowledge such as formulas and concepts, but doesn't know how to use these knowledge to solve problems, then his mathematics learning ability is very poor, and his learning efficiency and quality are also very low.

2. Broaden the thinking of solving problems

In mathematics teaching, teachers will guide students to think and find different methods to solve problems. Therefore, students should make good use of these opportunities, broaden their way of thinking and cultivate their own thinking ability. Through these methods, students can exercise their thinking ability and adaptability, learn to draw inferences from others, and thus improve their math scores.

3. Make good use of the wrong set of questions

In the process of learning, students will inevitably make mistakes. At this time, it is necessary to integrate and summarize the wrong questions and establish a set of wrong questions. With the help of the wrong problem set, students can know the reasons for their mistakes and master the correct problem-solving methods, so as to avoid making the same mistakes again. In addition, in the process of learning, we should always look through the wrong set of questions to deepen our impression, so as to remove the shortcomings of knowledge and make up for the loopholes in knowledge.
