I'm in grade one now, and I have some experience with my math teacher. It is not easy to be a good math teacher, especially a senior math teacher. Many topics have to be talked about more than ten times, but some people still can't. Especially in senior grades, we should teach students in accordance with their aptitude and use special methods for some very smart students, otherwise it will ruin the children's life. In addition, due to the relationship of mathematics, teachers will inevitably drag their feet, and students will have opinions and speak ill of you behind your back (as I did in fifth grade), so you have to bear with it. Kindness is often regarded as the liver and lungs of a donkey. So it is difficult to be a good primary school math teacher.
