纵观近年来中考试题的命题,不难发现,命题者越来越重视能力考查.这就要求:数学学习应走出题海,立足课本例题和习题,通过变式、拓展等方式,提高数学学习能力.本文以苏科版教材八(下)“反比例函数”一章中的一道课本习题为例,通过变式拓展、类比延伸,把“小”题进行“大”做,变会做一道题为会做一类题,供大家学习和参考.原题:[新苏科版教材八(下)第145页“探索研究”的第13题]我们知道,一次函数y=x-1的图像可以
Throughout the examination questions in recent years, the proposition, it is not difficult to find that more and more people pay attention to the ability to test the proposition.This requires: mathematics learning should come out of the sea, based on textbook examples and exercises, through variation, expansion, etc., to improve mathematics learning Ability.This paper takes a textbook exercise in Chapter 8 of the Suke Textbook as an example, and expands it by analogy, extending “analogy” to “big” , Change will do a title will do a class of questions, for everyone to learn and reference. Original title: [The new Suke Edition textbook eight (next) p145 “explore the study,” the first 13 questions] We know that once Image of function y = x-1 can be
