First, a clear teaching objectives, a reasonable set of unit teaching methods:

When designing elementary school mathematics unit teaching from the perspective of discipline, teachers need to make clear that the knowledge content of textbooks is set according to different units. Therefore, when teaching, teachers need to combine the knowledge content of textbooks and students' actual learning situation to formulate corresponding teaching objectives, so that the teaching plan can meet the teaching standards.

Second, pay attention to students' situation and make clear the basis of unit teaching design;

From the perspective of discipline concept, teachers should actively pay attention to the actual situation of students, deeply understand students, and comprehensively analyze students' mathematical basic reserves, hobbies, mathematical literacy development, study habits, learning cognition and so on.

Third, analyze the teaching requirements and put forward specific unit teaching objectives:

From the perspective of subject concept, teachers should combine the above-mentioned learning situation, aim at the core concepts and combine the basic requirements of teaching, refine the overall knowledge of the unit in a planned and purposeful way, decompose the knowledge points of the unit, and formulate specific and clear teaching objectives.

Fourth, build a knowledge framework and integrate unit knowledge content:

From the perspective of subject concept, teachers should further construct the unit knowledge framework, highlight the subject concept, clarify the core concepts of the unit curriculum, sort out and integrate the unit knowledge content, and present the unit knowledge teaching content to students in an intuitive and clear form.

Five, the basic problem guidance, driving students to explore the subject knowledge system independently:

From the perspective of big concept, teachers should realize the important role of questions, put forward mathematical questions, guide students to think deeply after the questions, and urge students to actively explore mathematical curriculum knowledge. Teachers should grasp students' subjective consciousness and let students explore and solve problems actively.

To sum up, the subject concept is a novel teaching concept. It is necessary to think about the knowledge content of mathematics textbooks from a holistic perspective, design teaching, implement teaching plans and build a scientific unit teaching model based on the mathematical knowledge system.
