前苏联著名教育家斯托利亚尔在他所著的《数学教育学》一书中指出:“数学教学是数学(思维)活动的教学”。可见,数学活动应成为小学数学课堂教学中重要的教学形式。让学生动手操作有助于他们对概念的深刻理解,有助于发展学生的空间观念。因此,课堂中要多安排学生动手画画、剪剪、拼拼、量量、摸摸、数数等。让他们通过操作和实践获取知识、理解知识,从而积累活动经验,发展思维能 In his book Mathematical Education, Stallar, a famous educator in the former Soviet Union, pointed out: “Mathematics teaching is the teaching of mathematics (thinking) activities.” Visible, mathematics activities should be an important teaching form in primary school mathematics classroom. Getting students hands-on helps them understand the concept and helps to develop the student’s perception of space. Therefore, the classroom should arrange more students to draw, cut, spell, quantity, touch, number and so on. Let them gain knowledge and understand knowledge through operation and practice so as to accumulate experience of activities and develop thinking
