在课堂教学中,我们要善于挖掘数学内容中的生活情景,从学生熟悉的生活情景和感兴趣的事情出发设计数学活动,使学生如身临其境,激发学生去发现、去探究、去应用,真正体会到生活中充满着数学,感受到数学的真谛与价值。例如,有一次,我在数学活动课时,顺手拿起讲台上的大半瓶墨水瓶说,这只墨水瓶,下面是长方形,上面是无名形体。新买来的墨水瓶装得满满的;净重1000克,现在墨水用去了一些,已经到了瓶的长方形体的部分,谁能想办法算出剩下的墨水还有多少克呢?题目一出,同学们七嘴八舌地议论开了,经过一阵子的讨论,基本上达成了共识:①第一种方法:可以用秤称:
In classroom teaching, we should be good at digging the life scene in mathematics content, design the mathematics activities from the students’ familiar life scenes and interesting things, so as to make the students immersive, inspire students to discover, explore and apply , I really feel that life is full of math, feel the truth and value of mathematics. For example, on one occasion, during my math activity class, I picked up most of the inkwell on the podium and said that the inkwell was rectangular below with no name on it. Newly purchased ink bottles loaded full; net weight of 1000 grams, now the ink used to some, has come to the rectangular part of the bottle, who can think of a way to figure out how much of the remaining ink grams? Topic a, The students rumbled to open the discussion, after a while of discussion, basically reached a consensus: The first method: you can use the scale said:
