However, it is normal if the decline is not much. In junior high school, the study pressure will be much greater. When you enter a new environment and face many new classmates and teachers, you will inevitably feel a little uneasy. Moreover, in junior high school, mathematics is a new stage, which is completely different from primary school. Some declines are normal, but you should control them, not too hard or too relaxed.

For math learning, follow the following points, I believe it is enough to go up a storey still higher:

1, on this basis, master the basic knowledge;

2. Do a good job in knowledge points and sort out difficulties;

3. Make a mind map of each unit to ensure that you master book knowledge;

4. Do more hands-on verification of mathematical formulas, and get better results through practice than rote memorization;

5, do more questions, not brush questions, but see why the teacher wants to ask questions, what knowledge points he wants to test, and what knowledge points can be combined.

In addition, pay attention to cultivate children's interest in mathematics learning.
