数学是思维的体操。而思维则是从人的动作开始的,切断了动作和思维的联系,思维就不能得到发展。因此,我们要根据小学生的年龄特点和认识知规律(动作感知——建立表象——形成概念),根据教学内容积极创设条件,组织学生操作学具,通过学具操作参与知识的形成过程,在学习知识的过程中,提高数学能力,发展数学思维。在小学数学学习中,实践能力培养的一个很重要的方面就是动手操作。因 Mathematics is the gym of thinking. The thinking is from the human action began, cut off the connection between the action and thinking, thinking can not be developed. Therefore, according to the age characteristics of pupils and their cognizance of cognitive rules (action perception - establishment of appearances - formation of concepts), we should actively create conditions according to the teaching content, organize students to operate learning tools and participate in the formation of knowledge through learning tools. In the process of learning knowledge, improve mathematics ability and develop mathematical thinking. In primary school mathematics learning, practical ability training is a very important aspect of hands-on operation. because
