一、说教材本节课是北师大版小学二年级数学上册第六单元测量中第一课内容。课标要求经历“直接比较、运用非标准长度单位测量、运用标准长度单位测量”三个过程,这样可以帮助学生对标准长度单位的意义有充分的理解。本节课通过测量活动,让学生体会量的概念,为后续正式学习长度单位做好准备。二、学情分析学生在一年级时已经积累了比较直接长、短的活动经验,对长和短有了一定的认识,能想出很多测量的方法。但由于学生年龄小,引导学生小组内互助解决问题尤为重要。三、说教学目标1.知识目标:积累测量活动经验,发展度量意识和能力。2.能力目标:经历用不同方式测量教室长度的过程,体会测量方式、测量工具的多样性。3.情感态度价值观:在测量活动中培养学生互助、交流表达的能力。四、说教学重、难点教学重点:积累测量活动经验,发展度量意识和能力。教学难点:在测量活动中培养学生合作互助、交流表达的能力。
一、教材的地位与作用 本节主要学习一元一次不等式组及其解集的概念,并要求学生会用数轴确定解集。它是一元一次不等式的后续学习,也是一种基本的数学模型,也为下节和今后解决实际生产和生活问题奠定了坚实的知识基础。另外,整个学习的过程中数轴起着不可替代的作用,处处渗透着数形结合的思想,这种数学思想会一直影响着学生今后数学的学习。二、学情分析从学生学习的心理基础和认知特点来说,学生已经学习了一元一次不等式,并能较熟练地解一元一次不等式,能将简单的实际问题抽象为数学模型,有一定的数学化归能力。但学生将两个一元一次不等式的解集在同一数轴上表示会产生一定的困惑。这个年龄段的学生,以感性认识为主,并向理性认知过渡,所以,本节课的设计是通过学生所熟悉的问题情境,让学生独立思考,合作交流,从而引导其自主学习。
在第1环节基础上,再让同学认识到函数Y=2X-1的图象与方程2X-Y=1的对应关系,从而把两个方程组成方程组,让学生在理解二元一次方程与函数对应的基础上认识到方程组的解与交点坐标的对应关系,从而引出二元一次方程组的图象解法。3、例题训练,知识系统化通过书上的例1,用作图象的方法解方程组,让学生明白解题步骤与格式,从而规范理顺所学的图象法解方程组,例题由师生合作完成,由学生说老师写的方式。4、操作演练、形成技能让学生独立完成书P208随堂练习,给定时间,等多数学生完成后,实物投影其完成情况,并作出分析与评价。5、变式训练,延伸扩展通过让学生做收上P208的试一试,而后给一定时间相互交流,并请代表发言他的所悟,然而老师归纳总结,并让学生通过自已尝试与老师的点拔从“数”与“形”两个方面初步体会某些方程组的无解性,进一步发展学生数形结合的意识和能力。6、检测评价,课题作业

一、知识和能力目标通过本单元教学,使学生能运用所学英语,正确地描述物体的颜色;同时进一步学习分辨人物的用语,并加以运用。二、过程和方法目标本单元口语训练应当自始至终在一种鲜明的色彩背景下进行,旨在营造那种为学生所喜爱的欢快气氛,教师应当在十种颜色上大做文章;在使用实物时要使颜色醒目;在组合图画时,要尽量用大色块;在使用投影时要使颜色突出来。教师可以从教室环境上入手营造色彩气氛,如:选取十种颜色的硬色板,剪成各个大写字母;或者将色板剪成各种卡通动物形象,悬挂在教室当中或在墙上,注明各种颜色的英语字块。三、情感态度和价值观目标用各种可以调动学生积极性的活动来提高学生的活跃性,激发他们参与讨论的热情。同时可以对学生进行美育教育,从小培养他们对美的正确认识。
本单元主要学习名词所有格 ('s 所有格 ) 的构成和使用。在初次接触 “ 名词所有格 ” 时,学生较难理解的可能是 “ 所有格 ” 这个名称,对于它的构成,学生也许会觉得较容易。教师可通俗地告诉学生 “ 所有格 ” 的意思是表示 “…… 的 ” ,这样学生反而容易接受。在使用 “ 名词所有格 ” 形式时,学生容易犯错误或混淆的主要是:将这种一 's 构成形式与 is 的缩写形式混淆,如: My father's name's Jin Zhi .,可以这样告诉学生:名词所有格的后面一般应接名词;勿将这种一 's 结构盲目套用与人称代词上,代替物主代词使用,如 He's father's name is Li Cheng 。在教学初期,可不讲授名词所有格的其它形式,待时机成熟,再向学生介绍复数名词所有格形式的结构一 ' ,如: the students' bikes 。 Self Check 教学内容 Self Check( 教材 P52) 教学目标 知识与能力 复习词汇 birthday , date , month , January , February , March , April , May , June , July , August , September , October , November , December , date , birth , age , old , speech . contest . trip , party , event , an , festival , pop , concert , chorus , lecture , music ;引导学生复习、巩固“询问和谈论日期”的目标语言并运用所学知识安排活动。
