Three Key Points of Elementary Mathematics Teaching Design from the Perspective of Deep Learning: Taking "Area of Parallelogram" as an Example

Deep learning has become a hot topic in the field of education. With the core content of primary school mathematics subject as the core content of mathematics subject, through carefully designing problems, it causes students' cognitive conflicts, guides students to participate in learning activities, and explores deeply around challenging learning topics, so that students can experience the meaningful learning process of success and development. Deep learning focuses on students 'overall understanding of a kind of knowledge content, forms the transfer of knowledge and methods, grasps the mathematical essence of the content they have learned, experiences the mathematical thinking method of the content they have learned, and promotes the development of students' key abilities and core qualities. Taking "the area of the parallelogram" as an example, this paper explores the three main points of deep learning teaching design, closely following the core content of the subject, highlighting the nature of mathematical knowledge and the connection between communication knowledge.
