Secondly, mathematical methods refer to the methods and strategies used by students in learning mathematical knowledge and solving mathematical problems. Mathematical methods mainly include observation, induction, deduction, variation, abstraction and popularization. Observation means that students find clues to solve problems by observing the laws and characteristics of problems. Induction means that students can find out the general rules by observing the known facts and examples, so as to solve problems. Deduction means that students draw conclusions through known premises and certain logical reasoning. Variant means that students can change the data and conditions in the problem and find out the essence of the problem or other solutions. Abstraction means that students can simplify complex problems into forms that are easy to understand and solve. Promotion means that students can apply existing knowledge and methods to other similar problems. Cultivating students' mathematical method ability can make them use mathematical knowledge to solve problems more flexibly and improve the effect of mathematics learning.
Finally, mathematical emotion refers to students' emotional experience and attitude in the process of learning and solving mathematical problems. Mathematics emotion mainly includes initiative, interest, self-confidence and patience. Initiative refers to the process that students can actively participate in mathematics learning and problem solving. Interest means that students are interested in and happy with the content of mathematics learning and problem solving. Self-confidence means that students have some confidence in their ability to learn mathematics and solve problems. Patience means that students can persevere in the face of difficulties and setbacks and don't give up easily. Cultivating students' mathematical emotional ability can enhance their enthusiasm and initiative in learning mathematics and improve their learning interest and learning effect.
To sum up, the core literacy of primary school mathematics includes three aspects: mathematical thinking, mathematical methods and mathematical emotions. Cultivating students' mathematical thinking ability can improve their problem-solving ability and innovative thinking; Cultivating students' mathematical method ability can make them use mathematical knowledge to solve problems more flexibly; Cultivating students' mathematical emotional ability can improve their enthusiasm and initiative in learning mathematics. By comprehensively cultivating these three qualities, students' mathematical ability and interest in learning can be comprehensively improved.
