First, be very, very strict. Don't smile and keep a straight face in class, pretend that no one will provoke my attitude, and severely punish students who don't listen carefully in class, so as to make an example for them and make them afraid to listen to your class;

Second, communicate with students after class, play activities and play interpersonal cards. Imagine that every student likes you very much, so you will obviously listen to your class carefully;

Third, change your teaching style, don't be too rigid, connect with reality, and always put boring formulas on what everyone is interested in, so that the classroom atmosphere will be active, and children who don't attend classes will ask the people next to them what the teacher said;

Fourth, don't leave too many difficult homework, which will not only burden students, but also make them lose confidence in mathematics and encourage them more. After all, I am a child, and I like to listen to other people's praise and praise. After answering, please contact your reality and make appropriate adjustments.
