Mathematical core literacy includes six aspects: mathematical abstraction, logical reasoning, mathematical modeling, mathematical operation, intuitive imagination and data analysis. 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.

Students' mathematical literacy can not be cultivated in a day or two, and it takes a long process to achieve it. In primary school mathematics teaching, optimizing and improving teaching methods plays an important role in cultivating students' mathematical literacy.

Methods of Cultivating Students' Core Literacy

1, 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.

2. 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.
