10的分与合教学反思.pdf

学习必备欢迎下载10 的分与合教学反思赖自伦本节课是分与合单元最后一个新授课，由于前面学生已经学习了 25、6、7 的分与合、8、9 的分与合，再学习类似内容，学生可能会没觉得新鲜感，但是这一节课又显得十分重要，因为10 的分与合是用“凑十法”教学进位加法和用“凑十法”教学退位减法的基础。所以，基于以上两个冲突，我在教学时，组织学生多样化的学习，让学生在多样化的学习活动中感受学习数学的快乐，学好本节课。为了突出重点，突破难点，在教学方法上我主要采用情境教学和引探教学法。一、创设情境、导入新课。这一环节我创设了猴妈妈带猴宝宝到果园里收果，请学生帮忙分9 只猴宝宝的生活情境，把学生从严肃的课堂气氛中带入到实际生活中，以此来调动学生学习的积极性，使学生产生强烈的学习欲望，从而形成良好的学习动机，为学习10 的分与合教学作了很好的铺垫。二、主动探索、学习新知。这一环节我先让学生数每串智慧珠有几个，并同时板书“10 的分与合”。接着我让学生观察，比一比，第一串和其它四串有什么不同?记得有这样的一句话“儿童的智慧在他的手指尖上”，所以我有目的、有意识地安排了让学生分一分、涂一涂、说一说等实际操作，启发学生学会用手操作、用眼观察、用脑思考、动口归纳的学习方法。接着让学生说看到了10 的这五种分法，还能想到什么?我根据学生说学习必备欢迎下载出的不同分法，板书 10 的另外五种分法，接着引导学生观察第一种方法从大到小的顺序；第二种方法从小到大的顺序。这一层次我注重让学生自主探究，主动递构建知识结构，注意让学生自己动手实践，积累感性认识，并经过大脑的加工思考，达到理性的认识。学生不仅有序地分，自己总结出了对10 的分与合的有序表述和有序记忆的方法，而且获得了数学活动的经验。三、智慧闯关游戏活动，应用拓展。在练习巩固的“想想做做”中的习题，我以智慧闯关游戏活动，因为一年级的学生刚从幼儿园过渡到小学，他们注意的稳定性和持久性较差，所以这一环节我利用课件设计了五关闯关游戏，再次激发学生参与学习的积极性。例如：学唱儿歌谁最棒，猜一猜、摘果游戏、芝麻开门、开火车。让学生在愉快的情境中有效巩固了10 的分与合，集知识性、趣味性、活动性为一体，使学生在知识和情感反面达到双重升华。在课堂作业中，我发现：学生基本上会做有关10 的分与合的练习，（只有两个学生由于智力问题没能掌握），并能有次序的记住10的分与合。我认为本节课能突破教学重难点。不足之处：学生的个性没有得到充分的发挥。在上新课的环节怕维持不了纪律，没能让学生进行讨论，今后要逐步改变，在教学中要让学生学会在合作交流中学习。今后打算：我将进一步加强自身的业务知识水平，并加强学生的教学常规训练。文档编码:CY4F7X2H7T5 HN2P8A6W5N1
