数学教材中的“你知道吗?”栏目,如同美味佳肴中的调味料,菜肴因为有它而变得更加鲜美。同样,教材中也因有它才使得数学学习更贴近生活,它所蕴含的古今中外数学计算方法,计算工具的产生和发展史,中外数学家的奇闻趣事更是不可多得的数学营养。但这么宝贵的内容仅仅因为不列入考试而变得暗淡无光,没能得到师生应有的重视。所以,尝试着在课前使用链接资料,作为新课的导入;课中使用链接资料,作为重难点的突破;课后使用链接资料,作为知识的拓展。以这种灵活处理教材的方式,为链接资料提供了更多创造性发挥的空间,从而使得链接资料更好地服务于新课,全面提升学生的数学素养。
“Did you know that?” Column in math textbooks, like sauces in delicacies, because dishes become more delicious because of it. Similarly, teaching materials also make mathematics learning closer to life because of it, which contains the ancient and modern mathematics calculation method, the calculation tool generation and development history, Chinese and foreign mathematician’s Gonzo is rare mathematical nutrition. However, such a precious content has just become dull because of not being included in the examinations, failing to receive the due attention of teachers and students. Therefore, try to use the link before the class information, as the introduction of the new class; the use of link data in class, as a heavy and difficult breakthrough; after-school use of link information, as the expansion of knowledge. With this kind of flexible processing of teaching materials, more creative space for linking information is provided, so that the link information can better serve the new curriculum and improve students’ mathematical accomplishment.
