Unit integration teaching is based on students' existing mathematical cognitive structure and learning ability, deeply analyzing the teaching materials, excavating the essence of the subject, re-integrating and creating relevant knowledge points.

Pay attention to the integrity and structure of knowledge, highlight the "theme" of the unit, and optimize teaching behavior and thinking with the training goal of "discipline core literacy"

Based on the integrated perspective, based on students' existing mathematical cognitive structure and learning ability, unit teaching deeply digs into the essence of mathematical knowledge, and establishes a unit teaching "theme" connected with the core literacy system of mathematics discipline to ensure the integrity and structure of students' learning content. On this basis, teachers should rationally plan and adjust the learning content, go beyond the characteristics of the subject, meet students' individualized learning needs and develop students' mathematical thinking.
