数学源于生活,从生活中产生、发展、升华,生活中充满着数学,小学数学教材中的许多概念、原理都可以在生活中找到其原型,进入小学学习的学生有了一定的生活经历和经验,已经积累了相当多的数学表象,如果教学中不重视数学知识与实际生活的联系,只重视培养学生的计算能力和解题能力,学生的实际应用能力自然就差了,也就更谈不上数学意识的培养了。一、让数学法则“生活化”在三年级教学“加减法的一些速算法”中有“324+199=324+
Mathematical origins in life, from life, development, sublimation, life is full of mathematical, primary school mathematics textbooks in many of the concepts, principles can find their prototype in life, entering primary school students have a certain life experience and Experience, have accumulated a considerable number of mathematical representations, if the teaching does not attach importance to the connection between mathematical knowledge and real life, only focus on training students’ ability to solve and solve problems, the practical ability of students naturally worse, also talk more No mathematic awareness training. First, let the mathematical rules ”life “ in the third grade teaching ”some of the addition and subtraction algorithm “ in the ”324 +19 = 324 +
