小学数学人教版五年级上册《解方程》说课稿
二、说教学目标知识与技能：初步理解“方程的解”和“解方程”的含义，以及之间的联系和区别。能用等式的性质解形如X±a=b的方程，掌握解方程的格式和写法。初步学会检验某个数是否是方程的解，培养学生检验的习惯，提高计算能力。过程和方法：通过探索、讨论、交流等活动，让学生初步理解“方程的解”和“解方程”的概念。经历运用等式的性质探究方程解法的过程，体会方程的解法和等式的性质之间的联系。情感、态度与价值观：1. 学生能积极参与数学学习活动，对数学有好奇心和求知欲。2. 在观察、猜想、验证等数学活动中，培养学生的数学素养。重点：方程的解和解方程的概念，初步掌握用等式性质来解简易方程的方法。难点：区别方程的解和解方程的含义。解方程的算理。三、说教法与学法教法：新课标指出，教师是学习的组织者、引导者、合作者，充分发挥学生的主体性。根据这一理念，我在教学中通过观察、猜想、验证等方式，自主探索、自主学习。有目的地运用知识迁移的规律，引导学生进行观察、比较、分析、概括，培养学生的逻辑思维能力。学法：①让学生学会以旧引新，掌握并运用知识迁移进行学习的方法；②让学生学会自主发现问题，分析问题，解决问题的方法。

方法总结：(1)若被开方数中含有负因数，则应先化成正因数，如(3)题．(2)将二次根式尽量化简，使被开方数(式)中不含能开得尽方的因数(因式)，即化为最简二次根式(后面学到)．探究点三：最简二次根式在二次根式8a，c9，a2＋b2，a2中，最简二次根式共有()A．1个 B．2个C．3个 D．4个解析：8a中有因数4；c9中有分母9；a3中有因式a2.故最简二次根式只有a2＋b2.故选A.方法总结：只需检验被开方数是否还有分母，是否还有能开得尽方的因数或因式．三、板书设计二次根式定义形如a（a≥0）的式子有意义的条件：a≥0性质：（a）2＝a（a≥0），a2＝a（a≥0）最简二次根式本节经历从具体实例到一般规律的探究过程，运用类比的方法，得出实数运算律和运算法则，使学生清楚新旧知识的区别和联系，加深学生对运算法则的理解，能否根据问题的特点，选择合理、简便的算法，能否确认结果的合理性等等．

属于此类问题一般有以下三种情况①具体数字，此时化简的条件已暗中给定，②恒为非负值或根据题中的隐含条件，如（1）小题。③给出明确的条件，如（2）小题。第二类，需讨论后再化简。当题目中给定的条件不能判定绝对值符号内代数式值的符号时，则需讨论后化简，如（4）小题。例3．已知a+b=-6,ab=5，求 的值。解：∵ab=5>0,∴a,b同号，又∵a+b=-6<0,∴a<0,b<0∴ .说明：此题中的隐含条件a<0,b<0不能忽视。否则会出现错误。例4．化简： 解：原式=|x-6|-|1+2x|+|x+5|令x-6=0，得x=6，令1+2x=0，得 ，令x+5=0，得x=-5.这样x=6, ,x=-5，把数轴分成四段（四个区间）在这五段里分别讨论如下：当x≥6时，原式=(x-6)-(1+2x)+(x+5)=-2.当 时，原式=-(x-6)-(1+2x)+(x+5)=-2x+10.当 时，原式=-(x-6)-[-(1+2x)]+(x+5)=2x+12.当x<-5时，原式=-(x-6)+(1+2x)-(x+5)=2.说明：利用公式 ，如果绝对值符号里面的代数式的值的符号无法决定，则需要讨论。方法是：令每一个绝对值内的代数式为零，求出对应的“零点”，再用这些“零点”把数轴分成若干个区间，再在每个区间内进行化简。

（1） 你是用什么方法解方程的？要求学生独立完成。请一位同学在黑板上计算。学生交流：等式的两边同时加上同一个数，等式仍然成立。也就是方程 x-9=15的两边同时加上9，抵消掉等式左边的9，这样等式的左边只剩下x。（2） 你会检验方程的解是否正确吗？指导学生把方程的解代入方程进行检验。2.出示：64页第2题的第2小题。提问：你是根据哪个等量关系列出方程的？（1） 标准体重+超出标准的重量=胖胖的体重（2） 标准体重-低于标准的重量=小明的体重提问：他们标准体重的计算方法有什么不同？学生交流：一个是等式两边同时减去同一个数，一个是等式两边同时加上同一个数。三、拓宽应用。1.解方程：x-5.3=10 75-x=402.65页第4题提问：你是怎样选出各方程的解的？把未知数的值代入方程，看看左右是否相等。3.65页第5题提示学生认真读题，注意选择题中所给出的条件是否有用。

二、探究交流，引导概括 —— 方程为了培养学生的发现和抽象概括能力，同时进一步理解方程的意义，我让学生分组学习，引导他们先找出②20+χ=100，⑥ 3χ=180，⑧100+2χ=3×50像上面三臄等式的有共同特征，然后归纳概括什么叫做方程？最后得出：像这样的含有未知数的等式，叫做方程。三、讨论比较，辨析、概念 —— 等式与方程的关系为了体现学生的主体性，培养学生的合作意识，同时让学生在解决问题的过程中得到创造的乐趣。通过四人合作用自己的方法创作 “ 方程 ” 与 “ 等式 ” 的关系图，并用自己的话说一说 “ 等式 ” 与 “ 方程 ” 的关系：方程一定是等式，但等式不一定是方程。四、巩固深化，拓展思维 —— 练习1 、“做一做”：2、判断是否方程3、“方程一定是等式，等式也一定是方程”这句话对吗？4、叫学生用图来表示等式和方程的关系。

（六）说教学策略1.专题性海量的媒介信息必须加以选择或者整合，以项目为依据，进行信息筛选，形成专题性阅读与交流；培养学生对文本信息“化零为整”的能力，提升跨媒介阅读与交流学习的充实感。2.情境化情境教学应指向学生的应用，建构富有符合时代气息的内容，与生活经验更加贴合，对学生的语言建构与运用有所提升，在情境中能够有效地进行交流。3.任务化以任务为导向的序列化学习，可以为学生构建学习路线图、学习框架等具体任务引导；或以跨媒介的认识与应用为任务的设置引导；甚至以阅读和交流作为序列化安排的实践引导。4.整合性跨媒介阅读与交流是结合线上线下的资源，形成新的“超媒介”，也能实现对信息进行“深加工”，多种媒介的信息整合只为一个核心教学内容服务。5.互文性语言文字是语文之生命，我们是立足于语言文字的探讨，音乐、图像、视频等文本与传统语言文字文本形成互文，触发学生对学习内容立体化和具体化的感悟，提升学生的审美能力。
