【Abstract】In the context of the stable development of the new curriculum reform, a variety of new teaching models are integrated into each stage of teaching, which promotes the effective improvement of education and teaching efficiency and provides more help for students' learning. Among them, in the process of junior high school mathematics teaching, due to the relatively high difficulty of mathematics knowledge involved, it is often difficult for students to efficiently master the content of textbooks when studying. Therefore, in order to effectively improve the efficiency of classroom teaching, teachers can appropriately use attributes and ideas, and incorporate cases to carry out teaching, mobilize students' interest in learning, and promote the improvement of mathematics classroom teaching. This article mainly analyzes the importance of the combination of number and shape in junior middle school mathematics teaching, and expounds relevant countermeasures for reference only.

一、應用数形结合思想的重要意义
数形结合思想的要点在于把数字概念和图形整合,而且初中阶段学生的学习需要得到教师的重视,部分学生对基础知识掌握不够充分,再加上数学难度相对较高,导致学生的学习效率无法得到有效提升。因此,要想提高教学效率,教师应该先提高学生学习的信心,并适当地将学生感兴趣的知识融入课堂,使学生掌握更多学习方法。在这过程中,数形结合思想对初中生的学习将产生较大的积极影响,学生运用这种思想能有效避免在学习的过程中受多种因素影响而无法完成知识的学习,帮助学生掌握知识概念,为学生日后的学习与解题提供更多帮助。不仅如此,应用数形结合思想,还能帮助教师在教学的过程中不断拓展教学模式,引导学生积极参与数学学习,并调动学生的学习兴趣,为学生未来的数学学习提供更多帮助。……
