    联系实际辨别意义效果好

     

    教学体积和容积的意义,为了帮助学生区分体积和容积的意义,特意结合即将到来的中秋节,引导学生回想看过的月饼礼盒,学生立刻兴奋起来,都说月饼礼盒很假!

     

    我明知故问:为什么月饼礼盒假呢?

     

    学生争先恐后的诉说月饼礼盒的罪状:从外面看,很大,很漂亮,可是打开一看,里面只有几个月饼,里面塞了很多泡沫和布匹。

     

    我沿着学生的思路追问:那联系我们今天所学的内容,说明月饼礼盒的什么较大?什么较小?

     

    很多人举手,请一个基础不太好的学生解答:也就是说月饼礼盒的体积较大,容积较小。

     

    我又趁势追问:为什么?

     

    再请一个基础较好的学生回答:因为从外面看,月饼礼盒较大,也就是说它占的空间大,打开一看,里面只装了几个月饼,说明礼盒能容纳的物体较少,也就是容积较小。

     

    说的真好!我们同学在生活中,可千万不要做像月饼礼盒一样,从外面看很大,很气派,很漂亮,,而从里面看却很少,很没有内容,要做表里一致的人。

     

    结合体积和容积意义的教学,我还不露痕迹的给学生上了一节思想教育课,可谓效果很好,而之所以能取得这样的效果,则要归功于能够联系实际引导学生辨别体积和容积的意义。所以,今后,我们要更多的联系生活实际来备课,来教学。
