在小学数学教学中,除了要使小学生学会某些基础知识和基本技能外,适时地渗透一些数学思想,这对发展小学生的智力,提高小学生的素质,是很需要也是很必要的。例如学习自然数,我们知道,自然数既有基数的意义(表示集合中元素的个数),又有序数的意义(表示集合中元素的排列次序),而在我们的日常生活中,不同的地方需要使用不同意义的自然数。当我们让一队学生从排头开始报数,如果最后一个学生报出的数是“十
In primary school mathematics teaching, in addition to enabling pupils to learn some basic knowledge and basic skills, it is necessary and necessary to develop some mathematics ideas in a timely manner. This is necessary and necessary for developing pupils' intelligence and improving the quality of pupils. For example, to learn natural numbers, we know that natural numbers have the meaning of cardinality (indicating the number of elements in a collection) and the meaning of ordinal numbers (indicating the order of elements in a collection). In our daily life, different places need Use different meanings of natural numbers. When we let a group of students report from the beginning of the row, if the last student reported a number of "ten
