新课标的改革使“空间与图形”这一新知识走进了小学低年级的数学课本。低年级的小学生学习此课程时,需要在老师的指导下,结合生活经验来对几何图形的概念加以理解,教师也要相应的帮助学生进行图形认识。结合小学低年级在“空间与图形”认知上的特点,对教师如何合理开展该课程的教学进行了研究。 The reform of the new curriculum makes the new knowledge of “space and graphics” into the lower primary mathematics textbooks. When studying this course, students in lower grades need to understand the concept of geometry under the guidance of their teachers and teachers. Teachers also need to help students to understand the figures accordingly. Combined with the cognitive features of “space and graphics” in the lower grades of primary school, this paper studies how teachers should rationally carry out the teaching of this course.
