Since it is the concept of reading, I think it is normal for students to be listless. After all, memorizing concepts in mathematics is boring and unnecessary. Generally, the concept of remembering is not the backrest, but it is generally familiar and remembered in the process of doing the problem.
I have a little suggestion, you might as well try it.
You can try to talk to your math teacher and ask him/her if he/she can ask some questions, which will usually familiarize students with the key concepts he/she asks to recite. I remember we did this when we were in the third year of high school (we don't have to learn math early in junior high school), and the effect was good. I really think it's not good to recite math.
You don't have to make a report, but just discuss the countermeasures with the teacher, otherwise you may have a bad relationship with your classmates. But you can ask your opinion and see what they want. It is estimated that they don't want to study. You should at least ask them to stop arguing and read books and do their own problems, otherwise they will probably waste their time chatting.
Try it first. This kind of problem is very common among students. Of course, some enterprising class cadres can make everyone obey by themselves, but if you don't have the courage, you can try to get on well with everyone first, because if you have a good relationship, they will confide in you even if they don't listen to you. Only by knowing what they think of you can you solve the problem.
