For the subject of mathematics, mathematics learning needs both logical thinking ability and logical thinking ability. In this regard, Bacon once said that "mathematics makes people cautious" is a well-known golden sentence. In fact, according to the data, children's 3-8 years old is the critical period of thinking cultivation, and 6 years old is the explosive period of thinking development.
