小学生学习数学的过程和具体的实践活动密不可分。操作实践是思维的源泉基础,是学生主动获取知识的良方。操作性的活动为学生积极探索、主动获取知识提供了机会,为学生感知数学的现实背景、来源创造了条件。因此,重视直观教学、重视实践活动和动手操作,重视让学生在活动中进行自主探索是发展学生思维,培养学生数学能力最有效的途径之一,更是学生学习方式的根本性转变。精心挑选操作内容,选择有效的操作方式、调控学生的操作过程、对学生操作结果的处 Primary school mathematics learning process and the specific practice are inseparable. Practice is the source of thinking is the basis for students to take the initiative to acquire knowledge of the recipe. Practical activities for students to actively explore and take the initiative to acquire knowledge provided an opportunity for students to understand the reality of mathematics background and source to create the conditions. Therefore, it is one of the most effective ways to develop students ’thinking and cultivate students’ math ability by emphasizing visual teaching, paying attention to practical activities and hands-on operations. Emphasis is placed on students ’autonomous exploration in activities. It is also a fundamental change of students’ learning styles. Carefully select the content of the operation, select an effective mode of operation, control the operation of the students, the result of the operation of the students
