所谓教师“懒一点”在本文是指,小学数学教师不要一味地认定小学学生年龄小,于是对学生们课前、课中和课后的所有大小事宜都为他们包办代替,而是不妨放放手,让学生自主去探寻数学的学习过程之美.钟启泉教师在课程与教学论中就指出:教学是教师与学生之间自由的交往过程,教学又是一种艺术化的存在.故,教师合理智慧的懒一点,将能够生发学生们的创造性思维和对数学美的鉴赏力和创造力.本文主要选取前置性学习、师生互动和课后练习三个 The so-called teacher “lazy ” in this article means that primary school mathematics teachers do not blindly assume that primary school students are young, so for students before class, after class and after all the size of the matter for them arranged instead, but may wish Release and let students autonomously explore the beauty of the learning process of mathematics.Zhong Qiguan pointed out in curriculum and teaching theory that teaching is a process of interaction between teachers and students and teaching is an artistic existence.Therefore, Reasonable and lazy, will be able to give birth to the students creative thinking and beauty of the aesthetic appreciation and creativity of mathematics.This paper mainly selects the pre-learning, teacher-student interaction and after-school exercises three
