Details are as follows:

1, lack of spatial imagination, poor classroom teaching effect. For example, when teaching courses such as the translation of graphics and the height of triangles, students have the characteristics of slow acceptance of knowledge and high error rate in practice.

2. Low computing power. For example, memorizing the multiplication formula, forgetting to carry, copying the wrong numbers, misusing the algorithm, slow operation and so on.

3. Poor ability to solve practical problems and lack of understanding of basic quantitative relations.

4. Inference ability is low, and questions are perceptual, jumping and imprecise.

5. It is easy to be distracted in class, slow to respond to teachers' questions, and lack necessary interaction with teachers and classmates (including eye contact and thinking exchange).

6. Lack of interest in math learning. The overtime of homework is serious, which leads to physical and mental fatigue, or seriously occupies the study time of other subjects.
