现在的小学数学课堂教学,因为课时比较少,作业题目比较多等种种原因,对于课堂上甚至是书本上的作业,大部分数学教师喜欢多讲作业,而很少深讲作业,导致学生数学思维浅显,思考问题方法单一。下面撷取课本中或作业本上的几道题目讲评案例,谈谈自己的一些体会。一、思维碰撞开出美丽花朵人教版数学三年级上册有这样一题:把10张卡片放入纸袋,随意摸一张,要使摸出数字1的可能性最大,数字5的可能性最小,卡片上可以是什么数字?请你
Nowadays, primary mathematics classroom teaching has many problems such as fewer classes and more homework assignments. Most math teachers prefer to do homework in class and even in books, while seldom explain homework, which leads students to think mathematically Shallow, think of the problem a single method. Below to retrieve textbooks or homework on the topic of several comments on cases, talk about some of their own experience. First, the collision of thinking out of a beautiful flower PEP three volumes have such a problem: the 10 cards into the paper bag, feel free to touch one, to make the possibility of finding out the largest number 1, the possibility of the smallest number 5 What is the number on the card?
