新课标提出,要培养学生的“应用意识”;华罗庚先生也曾说过:宇宙之大,粒子之微,火箭之速,化工之巧,地球之变,日用之繁,无处不用数学。这意味着数学与生活之间有着千丝万缕的联系。特别是小学数学,大都是实用性内容,与学生的日常生活联系更为密切。因此,培养学生的应用意识,应首先让学生认识到:数学离不开生活,生活中处处有数学。一、从生活中来1.数学知识起源于生活读数学史和数学符号史,笔者发现,数学知识的起源,大都来
The new curriculum proposed to train students “application awareness ”; Mr. Hua Luogeng also said: the universe, the micro-particles, the rocket speed, the cleverness of the earth, the change of the earth, the complexity of daily life, nowhere No math. This means that mathematics and life are inextricably linked. Especially primary school mathematics, mostly practical content, and students’ daily life more closely. Therefore, cultivating students’ sense of application should first make students realize that mathematics can not be separated from life and that there are maths everywhere in life. First, from life 1. Mathematical knowledge originated in life history of reading mathematics and mathematical symbols, the author found that most of the origins of mathematical knowledge
