So far, there is no strict and unified definition of mathematical literacy. Some people think that "mathematical literacy" is a relatively stable psychological state in which people acquire mathematical knowledge, skills, mathematical thinking methods, mathematical ability, mathematical concepts and mathematical thinking quality on the basis of congenital and influenced by acquired environment and mathematical education. In the words of Professor Gu Pei of Nankai University, "mathematical literacy" is what remains after all the mathematical knowledge you have learned has been discharged or forgotten. Primary school students' mathematical literacy includes five kinds of mathematical consciousness, namely, sense of number, sense of symbol, sense of space, sense of statistics and sense of mathematical application, four kinds of mathematical abilities, namely, mathematical thinking, mathematical understanding, mathematical communication and problem solving, and the development of mathematical values. I will talk to you about my superficial understanding of cultivating students' mathematical literacy from the following three aspects: 1. Understand the world from a mathematical point of view. Second, think in a mathematical way. Third, use mathematical methods to solve problems. First of all, look at the first aspect: understanding the world from the perspective of mathematics-the cultivation of mathematical consciousness. What is "mathematical consciousness"? For example, students can calculate "48÷4", which shows that students have the knowledge and skills of division. Students will understand, "there are 48 apples, with an average of 4 apples per person." How many people can you give them? " It shows that students have certain ability to analyze and solve problems, but none of them can show that students have mathematical consciousness. In physical education class, 48 students are jumping long ropes, and the teacher has prepared four long ropes, from which students can think of the formula "48÷4", which shows that students have a certain sense of mathematics. (1) Understand the meaning of numbers and the relationship between numbers, and cultivate a sense of numbers. There is a display board in the beijing museum of natural history: "1983, in the navigation survey conducted in the northeast, only two tigers were found in the forest of 7,000 square meters, so the Northeast Tiger was listed as a first-class protected animal." Xiao Yang of university of international business and economics thinks that a standard playground is bigger than 7,000 square meters. If there are two tigers in 7000 square meters, the number of tigers should be very large. How can they be listed as first-class protected animals? So why do so many tourists turn a blind eye to this explanation, while Xiao Yangcan finds the problem? On the one hand, I think Xiao Yang is good at observing and thinking, on the other hand, it shows that Xiao Yang has a good sense of numbers.
