When entering junior high school, many students will be very uncomfortable at first. First, the content of learning may be more difficult. In addition, the teaching methods are more flexible. Teachers don't stare at you all day, hug you and pave the way for you like primary school, so what students need more is to learn to study independently. I think your child's class teacher will tell you all this at the parent-teacher meeting. I just graduated from junior high school to senior high school. When I first entered junior high school, people around me told me so. It seems that it took two months to adapt to junior high school teaching. In fact, to be honest, I think junior high school mathematics is not difficult. What did you learn when you first entered junior high school mathematics? I don't remember exactly. Is it rational or real? These are just dead concepts. Function is more important in junior high school, and there are some simple geometric proofs. Recently, the dynamic graphic function problem is popular in the senior high school entrance examination, and your child should not have learned it yet. Anyway, don't worry. It doesn't matter that junior high school grades are a little lower than those in primary school. It's just that they haven't adapted yet, and they will get better gradually. But pay attention to take more notes! In primary school, I never took notes, but in junior high school, I may not fully understand the examples in class and need to go home and think. It's best to write them down, but be careful not to write them down when the teacher is talking. You can't do two things at once. The teacher may have passed an important sentence when you remembered it, but you didn't hear it. Isn't that a pity? So take notes and seize the opportunity. When I was in Grade One and Grade Two, mathematics was not very top-notch in my class. Suddenly, I won the first place in the final exam of senior two, and I have been doing well in math since then. And I don't engage in crowd tactics. I never buy counseling books. In addition, the decline in grades is not necessarily due to your child's poor study. It may be that other students in the class are also very strong, so they seem to be somewhat declining.
