小学数学知识不仅具有严格性,规范性的一面,而且具有灵活性,变通性的一面,二者是对立统一的。注意数学知识变通性的教学,恰当处理教材中的“一般”和特殊,“通常”和例外,不仅可以促进学生对知识的理解和掌握,达到融会贯通,而且有利于学生树立科学的世界观,提高创造性思维能力。本文试就如何进行数学知识变通性的教学谈几点粗浅看法。一、新授时为知识的变通性留出余地教学中,常有教师担心学生认知能力弱,把握不好知识的规律,习惯于过窄、过死地强调课本上的现 Primary school mathematics knowledge not only has a strict, normative side, but also has the flexibility, flexibility side, the two are the unity of opposites. Attention should be paid to the teaching of math knowledge variability, proper handling of “general” and special, “usual” and exceptions in textbooks, not only to promote students' understanding and mastery of knowledge, to achieve mastery, but also to help students to establish a scientific worldview and enhance creativity thinking ability. This article tries to talk about how to carry out the teaching of maths flexibility. First, the new teaching time to make room for flexibility of knowledge Teaching, teachers often worry about the students cognitive ability is weak, grasp the law of poor knowledge, used to too narrow, too stressed that the textbook is
