分数是小学数学的教学重点,它不仅表示一个具体的数,也表示部分与整体的关系,还可表示两个量的比值,可以说分数是学生从“真实可感的现实数学”向“纷繁复杂的抽象数学”的一次跨越。为此,分数教学决不能停留在“分数”本身,而要通过“分数”的教学找寻隐藏在其背后的数学支撑,从而让学生真正走进分数的世界。一、要经历“等分”的操作过程,不能重“结论”而轻“经
Score is the primary focus of mathematics teaching, which not only represents a specific number, but also that part of the relationship with the whole, but also that the ratio between the two quantities, it can be said that the score is from the students ”Complex Abstract Mathematics “ a leap. For this reason, the fraction teaching can not stop at ”score“ itself, but through the ”score“ teaching to find the mathematical support hidden behind, so that students really into the score of the world. First, to go through the ”“ points ”operation process, can not be heavy “ conclusion ”and light " by
