The fifth grade of primary school is a transitional period, and the psychology is a rebellious period. The knowledge points are difficult and complicated, which requires enough care and patience. In addition to listening carefully in class, you need to review and consolidate in time after class, otherwise you will fall behind! Especially in mathematics, there are many things to learn, and the knowledge points are easily confused. I suggest you be honest, that is, you must understand the knowledge points in class, and ask the teacher if you don't understand after class. I wish you success in your studies!
