简便计算是生活应用的一个缩影,如果脱离生活实际教简便计算,那么计算将会陷入机械状态,而孩子的学习也成了死记硬背地“套用”。这种学习方式,对孩子来说,是种负担,效率也因为学习状态低迷而低效。为了让简便计算真正地减负增效,教师在简便计算的教学上要精心设计,摆脱低迷、低效的状态,走向高效、高质。一、减负:摆脱低迷、低效(一)趣味开道要想减轻孩子的负担,首先就要摆脱孩子低迷的状态,这就要求老师在教学设计时,要趣味开道,不要一味地教计 Simple calculation is a microcosm of the application of life, if calculated from the actual life of teaching, then the calculation will fall into a mechanical state, and children’s learning has become rote “apply.” This way of learning, for children, is a burden, efficiency is also low because of learning conditions and inefficient. In order to make the simple calculation truly reduce the negative effects and increase the efficiency, the teachers should design elaborately in the teaching of simple calculation, get out of the downturn and inefficient status, and move towards high efficiency and high quality. First, the burden: to get rid of the doldrums, inefficient (A) fun way In order to reduce the child’s burden, we must first get out of the child downturn, which requires teachers in the teaching design, fun and clear-cut, do not blindly teach
