数与形是数学中的两个最古老,也是最基本的研究对象。“数”与“形”是贯穿小学数学教学始终的基本内容。数是数量关系的体现,形是空间形式的体现,两者是对立统一的,我们在探讨数量关系时常常要借助图形直观地进行研究;而在研究图形时,又常常要借助图形间隐含的数量关系求解。“数形结合”对教师来说是一种教学方法、教学策略,对学生来说是一种学习方法,如果长期渗透,运用恰当,就能使学生形成良好的数学意识和思想,长期稳固地作用于学生的数学学习。
Number and shape are two of the oldest mathematics, but also the most basic research object. “Number ” and “Shape ” is the basic content that runs through elementary mathematics teaching. Number is the embodiment of the relationship between quantity, shape is the embodiment of the form of space, the two are opposites unity, we often explore the relationship between the number of graphics with the intuitive study; and in the study of graphics, often with the implicit in the graphics The relationship between the number of solutions. “Combination of numbers and numbers” is a teaching method and teaching strategy for teachers. It is a kind of learning method for students. If it is used for a long time, it can make students form good mathematical consciousness and thoughts. Long-term Stabilize the student’s maths learning.
