数学思想是数学的灵魂,只有领悟了数学思想,才能体会数学的奥妙,掌握数学的精髓.下面谈谈怎样将数学思想渗透于“有理数”一章的学习之中.一、分类思想学习了有理数之后,很自然地得到分类:(?)在绝对值一节中有:|a|=(?)在有理数的乘方运算中有:(-1)`n=(?) Mathematical thinking is the soul of mathematics. Only by comprehending mathematics thinking can we understand the mysteries of mathematics and master the essence of mathematics. Now we will talk about how to permeate mathematics ideas into the study of the chapter “Rational Numbers.” I. Classification thoughts have learned rational numbers. After that, it is natural to get the classification: (?) In the Absolute Values ​​section: |a|=(?) In the power of rational numbers, there are: (-1)`n=(?)
