The core literacy of mathematics can be understood as the comprehensive ability that students should achieve in learning mathematics. Core literacy does not refer to specific knowledge and skills, nor is it general mathematical ability. Core literacy is based on mathematical knowledge and skills, which is higher than specific mathematical knowledge and skills. Core literacy reflects the essence and thought of mathematics, which is formed in the process of mathematics learning and has comprehensiveness, integrity and durability. Mathematical literacy is the quality that people have when they learn to know, understand and deal with things around them through mathematics. Usually it is the way of thinking and problem-solving strategies when people interact with their surroundings.

Second, teachers should change their teaching concepts.

In the past, for the sake of students' exam results, we used to make them recite concepts and formulas, do a lot of exercises and engage in sea tactics, thinking that they were "well informed." The more topics they practice, the more familiar and relaxed they will be in the exam, and of course the better their grades will be. But the fact is that mathematics, as a basic subject, especially our primary school mathematics, has laid a foundation for students' future study and work. If we only let them learn to cope with the exam now, they will feel very boring, which is very unfavorable to their study. If we strive to cultivate students' core literacy in mathematics teaching, these abilities can accompany them all their lives. For example, mathematical operations are always inseparable from our work and life; There is also data analysis, which we often use. The simplest example is to go shopping in the supermarket. We want to buy cheap detergent, and we have to analyze all the data collected before, and finally come to a conclusion: a brand of detergent is the cheapest. Therefore, in teaching, in order to cultivate and improve students' core literacy, our teachers must change their ideas, from the past thinking of attaching importance to exam results to developing students' ability and cultivating students' core literacy.

Second, to cultivate students' mathematical thinking

As we all know, mathematics is a subject that can best cultivate students' thinking ability, because everyone thinks that learning mathematics is not only to acquire mathematical knowledge, but also to cultivate and exercise our thinking ability in the process of solving problems. Mathematics teaching must be based on the cultivation of thinking, so as to improve students' mathematics core literacy. For example, when teaching this simple operation, for Uncle Li in the first picture, "I read 66 pages on the first day and 34 pages on the second day. This book has 234 pages. How many pages are there? " Then the textbook shows three children's algorithms and asks the students which is easier. I didn't ask students directly in class, but let them read the topic clearly first. Because textbooks are combined with our real life, we must let students understand the meaning of the topic. Whether "seeing" and "seeing" in the question are the same meaning requires students to read carefully, which is actually a step to train students to carefully examine the questions. This topic is not difficult. Observe the topic, see what the relationship between these numbers is, think about how we can calculate faster, and let them think about what law this is based on. Under such guidance, students will naturally transition from intuitive thinking to abstract thinking and know how to induce.

2 to improve the quality of mathematics classroom teaching

First, be good at activating students' existing experience in class.

Mathematics comes from life, and there is mathematics everywhere in life. In teaching, teachers should be able to consciously connect mathematics knowledge with students' real life and life experience according to the teaching objectives of each class, skillfully design lively, interesting and challenging activities, and turn mathematics knowledge into students' problems of exploring life, which can deepen students' understanding of the value of learning mathematics, stimulate students' feelings of exploring mathematics knowledge, and promote students' participation in classroom learning, thus improving the effectiveness of classroom teaching.

Second, actively create an open classroom

In mathematics class, we should provide students with opportunities to think, create, express and succeed, let students actively develop themselves, let teachers and students have a relaxed and rich class, organize colorful activity classes, organically combine education and teaching activities inside and outside the class, and stimulate students' interest in learning mathematics through a lot of hands, mouth and brain practice activities. Create questioning situations and present them with vivid and interesting examples to create a relaxed and harmonious teaching environment for students and encourage them to ask questions boldly. Only with questions can students think further, find something and create something. In this way, students will take the initiative to explore and develop, let students learn in activities, take the initiative to develop, gain wisdom in cooperation, innovate in improvement, encourage students to question boldly, make the classroom a place for students' personality development, and make the mathematics teaching process a process for students to fully express themselves and develop themselves. Such a free and open classroom is more conducive to the development of students' creativity.

Third, be good at capturing students' psychology.

Students at the same stage also have different psychology, just like some students like singing, some like dancing, some like painting, and so does math classroom learning. Some students like to raise their hands to answer questions, even if they are wrong, some students don't raise their hands easily even if they have answers in their hearts, and some students dare not raise their hands if they want to. At this time, it is necessary to prescribe the right medicine and mobilize the enthusiasm of all kinds of students. Good children can brag, especially primary school students. They are easily satisfied and easily injured. Every child has self-esteem and ambition, and they dream of surpassing others. They have the right to be recognized by society, classmates and teachers, but some students lack a strong sense of competition and self-confidence and need our support and help. We should try our best to arouse their enthusiasm for learning and encourage them to know and understand mathematics in practice and exploration.
