What a coincidence! I tried to talk about math in the third grade of primary school yesterday. There is no need to be nervous. If I didn't make other children more nervous than you, I only prepared two hours to go to the bookstore and buy a third-grade exercise book. You should show their parents that you are sincere and responsible for their children. You found several topics in your exercise book, including simple intermediate questions and questions. Let's see what level the child is at. I'll give you a student ID card first. Parents should take a look at their parents and understand their children's personality. Don't talk to him for a while. Ask him his name. Can you call him a nickname? This will bring him closer. Ask him what's interesting at school. Most children are nervous. Talk for a while and then ask him which subject he likes best. If he doesn't like math, don't be afraid to ask him why. Learning math well will make people smart. He talked about how he usually studied mathematics, and told him a set of your learning methods, using simple words as much as possible. They don't understand words such as knowledge points and test sites. Then, let him show his math level, that is, don't let him finish all the problems. You don't have to start one question after another. Let him talk about what the questions mean and how to solve them. Open the textbook catalogue and ask him what knowledge he uses to solve each question. In this process, I found that my child's application problems were not very good, so I focused on finding some application problems to teach her how to turn literal meaning into mathematical relations. We teach problem-solving methods, not just talking about problems. We should praise him occasionally, encourage him to have a good talk with his children after finishing the questions, ask him what doubts he has about you, and finally leave him your phone number, telling him that he can encounter difficulties in his study whether he is successful or not. After calling you, report to your parents about your child's general level and what you said, and tell them how you plan to coach your child in the future. I just followed this step, passed it once, and got the reward of trial. No problem. Take it easy. Good luck.
