Urgent! The child doesn't know the knowledge of division of mathematical fractions in primary schools. When I got home, my father and I took turns telling him that the child was still not good. What should I do? Maybe it's the wrong way to speak, and the child just can't understand. It is suggested to talk to the teacher to see where this part of knowledge is difficult, or where children find it difficult to understand. You can also buy a teaching aid, many of which are very detailed and vivid. For example, you can learn by yourself and explain it to your children in the way of knowledge explanation in the teaching assistant.
