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,教师要根据小学生的年龄特点和认识规律(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,培养能力,发展思维。 Mathematics is the gymnastics of thinking, and thinking begins with the action of man, cutting off the connection between action and thinking, and thinking can not be developed. Therefore, the teacher should according to the age characteristics of the pupils and the law of cognition (motion perception - the establishment of the image - the formation of the concept), actively create conditions according to the teaching content, organize students to operate learning tools, learning tools through participation in the formation of knowledge in learning In the process of knowledge, develop ability, develop thinking.
