Walking into the paradise of mathematics with students is a part of Wu Zhengxian and Elementary Mathematics. What impressed me most about this film is how to cultivate students' interest in learning. There are many examples, which are especially worth learning. Such as; When studying "Year, Month and Day", Mr. Wu asked the students to carefully observe the "calendar card" and say the number of days in each month. Students soon discovered the rule of 3 1 day and 30 days per month, except for February. Teacher Wu seized this phenomenon and designed the activity of "testing teachers". The students reported the year of their "calendar card". Please guess the number of days in February. The accuracy of the teacher's answer surprised the students, so they began to explore the law of knowledge in the year, month and day with questions and surprises.

There is also a lesson about the nature of decimals, in which students tell their feelings about "0" in an anthropomorphic tone. "The past' 0' how proud you are! How proud! If you stand behind the natural number, this number will expand because of your arrival. If you stand one, expand it by 10 times. Two stations are 1000 times bigger, and three stations are1000 times bigger ... which makes you always strut in front of the other nine brothers. Today we learned the nature of decimals, haha! It turns out that people don't pay much attention to the' 0' at the end of the decimal part. You won't change the size of the number with or without you. It seems that your existence is insignificant. 0' Ah, it's time for you to know yourself. Remember, modesty and prudence are virtues. "Under the guidance of Mr. Wu, the boring mathematical concepts filled students' hearts with the taste and interest of learning.

Mr. Wu also picked up interesting stories from ancient times, which are both delicious and can inspire children's wisdom. For example, after the death of Diophantu, a great mathematician in ancient Greece, his tombstone was engraved with a poem that attracted worldwide attention. The main idea of the inscription is: passers-by this is the place where Diophantine was buried. Please calculate the following figures to know how many winters and summers he has experienced in his life. One sixth of his life was a happy childhood, and one twelfth was a carefree teenager. In another seventh year, he will build a happy family. Five years later, my son was born, only to find that his son died four years earlier than his father, but his age was only half that of his father. The poor who lost their children in their later years. They spent their old age in grief. Please calculate, how old did Diophantine live to meet death?

Teacher Wu thinks that the task of primary school math teachers is not only to teach students the knowledge in textbooks. At best, it is a "porter." In order to enrich students' knowledge and improve their mathematical literacy, teachers should fully tap curriculum resources and introduce interesting historical materials and stories captured in the vast mathematical world into the classroom. Let children enjoy ancient classics and modern classics in a happy mood. Appreciate the charm of mathematics in solving problems, and experience the ideas and methods of mathematics in the process of appreciation. Only those of us who teach mathematics are first infected by the charm of mathematics, and those who study mathematics can be attracted by the charm of mathematics. We should make a fuss about improving students' mathematical literacy, and strive to let children solve practical problems scientifically and skillfully with mathematical ideas and methods.
