I think the child's math performance in the first grade is poor. As parents, we can accompany our children to do homework every day, help them preview and see what is the reason for his poor math. Sometimes a child is very clever, but in class, the teacher makes progress too fast for him to keep up, so he has no confidence in mathematics and his grades will get worse. First of all, you can communicate with your child and see where the reason is. If your child can explain the reason to you clearly, then it is good to solve the problem according to the reason. If your child is introverted, you can study math with him every day. Slowly see if the child's academic performance is really poor, or there are other reasons. Sometimes it's not that his children's learning ability is poor, but that they dare not take the initiative to ask questions when they encounter problems that they can't, which leads to backward and worse grades. When children's academic performance is poor, psychological pressure is also great, so when communicating with children, we must pay attention to ways and means, and never blame them loudly. When I was in junior high school, my math scores were very poor, because the teacher spoke too fast, and I couldn't keep up at all. Later, I gradually felt that mathematics was too difficult for me, and the class taught by the teacher was like a gobbledygook. I also blame myself for not taking the initiative to ask the teacher when I found out I couldn't, which led to poor grades. Fortunately, I got my grades back in the third grade, and I got good grades in the senior high school entrance examination. Therefore, as a parent, you don't need to worry too much, just communicate with your child and find out the reasons to help him improve his grades. Besides communicating with children, we should also communicate with their teachers. If the teacher speaks too fast, parents can also give suggestions to slow him down appropriately. Of course, everything still depends on the learning ability of the students in the class, and parents can't say whatever they want. But I believe that as long as * * * is the same, it will be effective, and I usually care more about my child's mood. Only when children are in a better mood will they be more motivated to learn.
