数学教学中教师给学生进行操作活动,例如:剪纸、折叠、度量、摆弄实物等,能激发学生学习兴趣,提高学生学习的主动性,帮助学生较快地理解与掌握有关的数学知识,也有利于培养学生发现能力与动手解决问题的能力。一般说来,小学数学的大部分内容的教学,都可有机会让学生进行一些操作活动,特别是涉及几何图形的教学,可以更多地利用操作活动来进行教学。比如图形长度、面积、地 Teachers in mathematics teaching activities to students, such as: paper-cut, fold, measure, tweak kind, etc., can stimulate students interest in learning, improve students' learning initiative, to help students understand and grasp the mathematical knowledge faster, there are Help to develop students ability to find and solve problems. In general, teaching most of the content in elementary mathematics can give students the opportunity to conduct some operational activities, especially teaching related to geometry, so as to make more use of operational activities for teaching. Such as graphics length, area, and
