I think starting from the fact that children's math scores are poor, in the process of communicating with math teachers, we should first express a positive attitude towards improving children's math scores, so that children's math teachers can clearly feel that your communication with him or her is to cooperate with teachers and improve children's math scores.

Never let the teacher think that you are blaming, so that the atmosphere is harmonious in the process of communication. With this premise, even if you say something inappropriate, the teacher can understand. It's best to apologize for the trouble caused by children's poor grades, so that teachers can help them.
