二年级数学5的乘法口诀教学反思(二套)目录：二年级数学5的乘法口诀教学反思一二年级数学乘法口算练习题二- 1 - / 10二年级数学5的乘法口诀教学反思一 本节课是乘法口诀教学的第一节课，由于学生已经学习了乘法的初步认识，了解到乘法的基本意义，也有了五个五个数数的经验，因此很容易得出2个5、3个5、4个5、5个5的和.先出现5的乘法口诀能较好地凸现乘法口诀的教学.学生在理解的基础上掌握5的乘法口诀，就为学习2、3、4的乘法口诀打下良好的基础.学生对于5的乘法口诀已经比较熟悉，一方面通过前面的学习，同学们能通过乘法的意义轻松的将加法算式改为乘法算式，另一方面5的乘法比较容易记，编口诀也不难.为了让学生学的更有趣一些，我对“5的乘法口诀”进行了适当的更改.由于5的乘法口诀是学习乘法口诀的开始，为了吸引学生我没有用课本上的情境图，而是用了孩子们都非常熟悉的手.在简单的复习之后使学生们动手画自己的小手，这样既锻炼了学生的动手能力又恰当的引入了课题.而手掌每个同学都有,一只手掌有五个手指就是1个5，两只手就有10个手指，也就是2个5，并列出加法算式.以此类推，一直到5只手，也就是5个5，写出加法算式.让学生根据写出的加法算式，改写成乘法算式并且引导学生从1个5开始编出口诀，让学生从具体的、直观的角度去理解乘法口诀的含义，更加符合学生的心理，不但有利于学生快速地记忆口诀，而且对学生理解乘法问题，解决乘法问题很有帮助.编口诀是这节课的重点，我先让学生说说意图，然后引导学生想到此处有几只手也就是有几个5，再让学生据此编口诀，通过乘法的意义理解口诀的意思，在这整个环节中，我很相信学生的能力，学生能解决的就让学生自己来解决，而不是由老师传授给他们.目的是尊重学生已有的生活知识，让学生来展现自己的本领，关注学生的情感、态度，体现学生的价值观，提高学生学习的兴趣和自信心.整节课学生参与的热情很高涨，效果也很好编完后大部分孩子都能背过5的乘法口诀.作为一节课的承担者，在没有走进课堂之前，对自己的设计还是很满意的，但是当你真正课堂去实施的时候，你会发现，这样那样的不足：首先此次课是赛课内容之一，赛课的重点是小组合作成效的一个考察，虽然这对于低年级的学生要求不是很高，但我们二年级的学生在此次课程的表现中还是不够好，虽然他们所有的小组成员是簇拥到了一起，但是有的还是没有把自己的真正想法大胆的说出来，让组员们进行商讨，有的甚至是自己在自己的草稿本上写写画画，已到达思考的效果，这就使得小组合作成效度有所降低，但大部分同学还是在积极的思考讨论.其次，自己没有把5的连加示意图画的仔细，以至于没能达到一目了然的效果.再次是板书没有安排恰当，以至于显得杂乱及没能达到更好的服务本节课知识的讲解.最后是上课时间的把握上有一些误差，尤其是在请同学回答问题时，有的同学不够大胆，不敢站起来直接说出思考结果，这就的要求在以后的学习中对这种同学多加训练.当然作为一个才走上讲台的新老师需要学习的东西还很多，希望以后在教学中，能够避免这样的事情再次发生在自己的课堂上，使自己的业务水平有所提升.4
