《现代汉语词典》修订本中解释:数学,研究现实世界的空间形式和数量关系的科学,包括算术、代数、几何、三角、微积分等。“数学”在数字中寻找、学习个中奥秘。(我从字面义分析)很奇妙的是,大街小巷中,不识字的老妪买卖东西时,算账又快又准。所以,我总在想,数学来源于生活,又服务于生活,最重要的就是计算。有许多绕头的实际问题,只要搞清数量关系,找到准确数据,就会迎刃而解。计算由易到难,重在引导学生探索算法。虽说基本技能的形成需要一定量的训练,但要适度,不能依赖机械的重复操作, The Dictionary of Modern Chinese Dictionary explains: Mathematics, the science that studies the relationship between the spatial form and the quantity in the real world, including arithmetic, algebra, geometry, trigonometry, calculus and so on. “Mathematics ” Find in numbers, learn the mystery. (I’m from a literal analysis) What’s amazing is that in the streets, when illiterate old people buy and sell things, they count them quickly and accurately. Therefore, I always think that mathematics comes from life, but also serve life, the most important thing is calculation. There are many practical problems around the head, as long as the number of relationships, find accurate data, it will be solved. Calculated from easy to difficult, focusing on guiding students to explore algorithms. Although the formation of basic skills requires a certain amount of training, but moderate, can not rely on mechanical repetitive operations,
