苏霍姆林斯基说过:“手和脑之间有着千丝万缕的联系,手使脑得到发展,使它更明智;脑使手得到发展,使它变成思维的工具和镜子。”课堂活动就是把学生手的动作和脑的思维结合起来,以活动促思维,调动学生各种感官参与学习。新课程标准指出:“有效的数学学习过程不能单纯地依赖模仿与记忆,教师应引导学生主动地从事观察、实验、猜测、验证、推理与交流等数学活动,从而使学生形成自己对数学知识的理解和有效的学习策略。”因此与生活相关的、有趣的和探索性的数学学习活动将成为数学课程内容的有机组成部分,特别是小学阶段,数学课更应该多开展课堂活动,让学生 Suhomlinski said: “There are inextricably links between the hand and the brain, and the hand develops the brain to make it more sensible. The brain develops its hand so that it becomes a tool and a mirror for thinking . ”Classroom activities are the combination of the actions of the students’ hands and the thinking of the brain, which promote the thinking through activities and mobilize the various senses of students to participate in the study. The new curriculum standard states: “Effective mathematics learning process can not rely solely on imitation and memory. Teachers should guide students to take the initiative to engage in mathematical activities such as observation, experiment, speculation, verification, reasoning and communication so that students can form their own knowledge of mathematics Understanding and effective learning strategies. ”" Life-related, entertaining and exploratory math learning activities will thus become an integral part of the content of math curricula, especially in primary school, and math classes should be more classroom activities to allow student
