认识序数的教学 进行序数变式的练习:“序数”是反映序列中每个物体的位置,序列是多样的,序列的方向不是固定的。但序数教学却多是排成整齐的横列,多是从左向右认序数。在初进行认序数时,这样做是必要的,整齐地排列,习惯性地排序,有助于幼儿较快地认识序列中的序数关系,但若总是这样让幼儿认序数,则会对序数的认识狭隘而固定,不利于形成序数的概念。因此,应在序数教学中,多进行一些序数变式练习,如下:
Ordinary number of teaching to understand the ordinal number of exercises: “ordinal number” is to reflect the position of each object in the sequence, the sequence is diverse, the direction of the sequence is not fixed. However, ordinal teaching is mostly arranged in neat rows, mostly from left to right to recognize the number. It is necessary to do this in the early stages of recognition of ordinal numbers. It is neatly arranged and habitually ordered, which helps young children understand the relationship of ordinal numbers in the sequence faster, but if so, The definition of narrow and fixed, is not conducive to the formation of the concept of ordinal number. Therefore, ordinal teaching should be more practice some ordinal variant, as follows:
