一、展现操作活动过程,在“做”中自主学习教师选择教学方法应根据学生思维的特点,结合内容的需要,有序地开展操作活动,让学生在操作活动中建立表象,在感性的基础上形成数学概念。例如,下面两题是两种不同的分法,因而确定了两个算式的含义不同。教师应引导学生通过操作活动,借助直观进行对比,抽象出除法运算的含义。 (1)把6个桃子平均分成3盘,每盘放几个? (2)把6个挑子每3个放一盘,能放几盘?
First, to show the process of operating activities, in “doing” independent learning Teachers choose teaching methods should be based on the characteristics of students thinking, combined with the content needs, orderly to carry out operational activities, so that students establish the appearance of operational activities, in the emotional basis On the formation of mathematical concepts. For example, the following two questions are two different divisions, thus determining that the two formulas have different meanings. Teachers should guide students through the operation of activities, with the intuitive comparison, abstraction from the meaning of division. (1) The average of 6 peaches divided into 3, put a few per plate? (2) Put 6 pick every 3 a plate, can put a few plates?
