一、仔细阅读,抓关键词法数学学习中概念、公式及规律的掌握是必不可少的,为了更好地掌握这些规律和概念,就要抓住其中的关键词。例如:判断题,一组对边平行的四边形叫梯形。对比梯形的概念,学生就会发现少了“只有”一词,而“只有”是梯形概念中最容易被忽略也是非常关键的一个词。少了这个词,“一组对边平行”就包括了“只有一组对边平行”和“两组对边平行中其中的一组对边平行”两种情况,与梯形的概念相悖,因此是错的。二、看清要求,查数量法
First, read carefully, grasp the law of mathematics learning concepts, formulas and laws of master is essential, in order to better grasp these laws and concepts, we must seize the key words. For example: determine the problem, a group of parallel to the side of the quadrangle called trapezoid. Contrasting the notion of trapezoids, students find that there is less word “only ” and “only ” is the most easily overlooked and crucial word in trapezoidal concepts. In the absence of this word, “a set of parallel to the side” includes both the “parallel set of only one set of parallel sides” and the “set of two parallel sets of side-to-side parallelism” in both cases, with The concept of trapezoids runs counter to each other and is therefore wrong. Second, see the requirements, check the number of law
