小学高年级学生的思维仍以形象思维为主,在理解抽象的几何知识和形成初步的空间概念时,受到诸多因素的影响。在教学过程中,教师应该引导学生积极参加实践活动,能激发学生学习兴趣,加深对知识的理解,培养其思维能力。让学生真正地获取数学知识和研究数学的方法,学会用数学思想提出问题、分析问题、解决问题。一、改革教学方法,为学生理解而教传统数学教学中教师是课堂的主宰者,学生的学习是在教师牵引下的被动的学习。实践证明,这种以教师为中心 The thinking of upper primary students in primary school is still mainly based on image thinking. Many factors influence the understanding of abstract geometric knowledge and the formation of preliminary spatial concepts. In the process of teaching, teachers should guide students to actively participate in practical activities, which can stimulate students’ interest in learning, deepen the understanding of knowledge and develop their thinking ability. Let students really get mathematical knowledge and mathematical methods, learn to use mathematical thinking to ask questions, analyze problems and solve problems. First, the reform of teaching methods for students to understand and teach Traditional mathematics teaching teacher is the master of the classroom, the student’s learning is a passive learning under the guidance of teachers. Practice has proved that this kind of teacher-centered
