Teaching content Compulsory education textbook Su teaching textbook fourth grade: vertical and parallel. 【Interpretation of knowledge】 “Intersection and parallelism” This part is one of the important basic knowledge in the field of “space and graphics”, which is of great significance to students’ further understanding and understanding of other related contents. On the other hand, The class opens up another spatial perspective for students to explore graphic research: the positional relationship can effectively help students accumulate learning experience of “space and graphics” and fully experience the unique value of activities such as observation, operation and exploration, which are beneficial to Improve students’ curiosity in mathematics and experience the fun of studying “Space and Graphics”.
