For such a thing, you can talk with the teachers of the school where your child belongs first, and get to know the main performance of your child's mathematics teaching at school. You need to firmly believe that the teacher still knows the children's learning status in the subjects he teaches. The reason why some children are unscientific and unreasonable is subjective, that is, they don't like teachers or teachers don't like students, which leads to the subject being abandoned by students for no reason. There are many ways to learn, and the way that suits you must be helped by the teacher and explored by yourself.
First of all, we must establish the specific reasons for students' poor grades. Some people don't like math and teachers, and teachers don't care about themselves. The surrounding learning environment is different from teachers, and they are lazy in thinking, and their way of thinking still stays in middle school. Many of my classmates are caused by students' emotional instability, not ability problems. Looking forward to communicating with children more, opening up the bad mood of learning mathematics and finding the root of the problem, excellent results are not far away. Shape your baby's self-confidence.
Don't let children be afraid of numbers, build up self-confidence that they can learn well. Secondly, to improve the basic knowledge of mathematics in middle schools, it is generally the lack of basic knowledge that will lead to unsatisfactory results in mathematics classes. Third, strengthen math practice and do more kinds of questions. The teaching strategies of high school teachers are completely different from those of middle schools and primary and secondary schools. Senior high school teachers don't change their homework, report their homework, send it back as it is, and then give the correct answers, so that students can grade and adjust themselves.
