1、学习好资料欢迎下载小学数学二年级上册说课稿乘法的初步认识一、说教材(一)人教版义务教育课程标准实验教科书数学二年级上册P.4446 乘法的初步认识(二)教学目标与策略选择1、教材分析本节教材主要是让学生在具体情境中体会乘法运算的意义,使学生认识相同数相加可以用乘法计算和乘法是相同数相加的简便方法。让学生掌握乘法算式的写法和读法,知道乘法算式中各部分的名称。2、学情简析学生已经学过加法、减法,表内乘法是学生学习乘法的开始,它是今后学习表内除法和多位数乘、除法的基础。由于学生没有乘法的概念,而且这个概念又难以建立,在这种情况下,教材一开始就专列了这一节内容,使学生理解乘法的含义,为以后学习乘法的其
2、它知识奠定十分重要的基础。3、设计意图根据“新课标”精神,我们在使用教材时,在深刻体会教材编排意图的基础上,一方面充分运用教材呈现的教学资源,另一方面又根据新理念,对教材资源做了适当的补充和调整,力图为学生创造一个和谐的氛围,使学生的学习活动通过自主探索获得成功体验,在生动活泼的情境中获得主动发展,并使学习过程富有个性化。4、目标预设 在认识几个几的基础上理解乘法的含义,认识乘号,会读、写乘法算式。在与相同加数连加的比较中体会用乘法写比较简便。培养观察、推理能力和学习数学的兴趣及合作意识。感受到数学与生活的密切联系,体验到生活中处处有数学。5、教学重点、难点理解乘法的含义学习好资料欢迎下载二、
3、说教法和学法本节课教学设计从四导入手,导入新课、导学新知、导练、导总结。教师在课堂教学中只起着带路人向导作用,学生困惑时给予启发,阻塞时给予点拨,上台阶时给予铺垫。攀登时,给予鼓劲。让学生在教师指导下自觉地发现新知,探究新知。参与知识形成的全过程。(一)、联系实际,设疑导新。好的开头是成功的一半。新课导入是课堂教学的重要环节,是一堂课成功的起点。本节课一开始从生活实例引入,让学生看图,听录音,算一算本班捐款情况。这样把数学与生活实际联起来,使学生感到生活中处处有数学,学起来有用处,就容易激发兴趣。然后设疑,问学生在“解答的过程中遇到什么困难?”怎么解决这种困难?”让学生产生去发现问题,解决问题
4、的强烈欲望,从而导入新课,学生跃跃欲进,激发了学生探求新知的欲望,为探求新知创下良好的开端。(二)、由 扶 到放,导学探究叶圣陶先生曾说:”当教师像是帮助小孩走路。扶他一把,要随时准备放,能放手就放手。例 1 的教学有三个层次,第一个层次是师生共同摆红花,教师指导写乘法算式。第二个层次是让学生自己摆方块,尝试写乘法算式。第三个层次是学生看图说留意,独立写乘法算式:这样由“扶”到“放”,逐步让学生探究新知。学生学习方法的指导也是先由教师指导写算式的方法,然后让学生小组交流小结写乘法算式的方法。一文档编码:CL2V6E3J9J4 HT10X3G9N10N10 ZK8J1L5X2V7文档编码:CL2

12、生积极主动参与知识的全过程,领悟到知识的真谛。同时,在由“扶”到“放”的过程中,始终遵循学生的认识规律:由具体形象到抽象,由感性到理性。引导学生通过自己的观察、思考、比较到动口说一说,概括出乘法的含义,建立表象,形成新的知识结构。同时也培养了学生探究新知的思维品质,促进思维的发展。3合理设计练习导练,强化新知。要达到学生掌握知识。最终发展能力的目的,学生的思维就必须经过反复多次,循序渐进的实际应用。本节课的练习有两个层次,第一个是基本练习,是让学生看图写出加法算式和乘法算式,使学生初步掌握求几个相同加数的和,还可以用乘法算,并能正确写出乘法算式。第二个层次是综合练习。形式上多种多样,生动有趣,
