有一种战术称持久战,一般都是用在军事上的一种战术,是抗战时期的重要战术之一。持久战的意思是指持续时间较长的作战。从小学低段开始在数学教学中有意识地向学生渗透数形结合的思想,这样对教师今后的数学教学以及对学生的后续学习都具有十分重要的意义。可是想从低段提及数形结合的数学思想并不是件容易的事情,数与形在小学数学教学中是一个重要的数学思想,又是解决数学问题的重要方法。我认为要在低龄儿童中渗透
There is a tactic called protracted war, which is generally used in military tactics and is one of the important tactics during the war of resistance against Japan. Protracted war means longer-duration operations. Beginning from the lower part of primary school in mathematics teaching consciously to penetrate the idea of combining numbers with form, so that the teachers in the future of mathematics teaching and follow-up study of students are of great significance. However, it is not an easy task to refer to mathematical combination of figures and figures from the lower part. Number and shape are an important mathematical thought in primary mathematics teaching and an important method to solve mathematical problems. I think we should infiltrate the younger children
