教学重点和难点:运用所掌握的语言描述,比较不同地点的特点。在练习中学习掌握英语比较级和最高级的用法。课前准备分配小组,每组五至六人。通过上网或翻阅报刊杂志等方法,确定旅游线路,做出基本的旅游计划。教学设计:本节课流程图 学法指导:1.由于这是一堂新课,在教学中应注意面向全体,发挥学生的主体性,引导学生积极参与,激发学生的求知欲和学习积极性,指导学生积极思维,主动获取知识,养成良好的学习方法。逐步学会独立解决问题。总之要尽可能调动学生的非智力因素促进智力因素的发展。教法选择:1.电化教学法2.课堂讨论法3.任务型教学法采用这些方法的目的是为了充分调动学生的学习积极性,使学生变被动学习为主动学习。通过电脑形象的演示,加强印象,提高兴趣,突破难点,提高教学效率,进而增大教学的容量和信息量。充分体现教师为主导,学生为主体的教学原则。
内容提示1.本单元主要内容是学会used to结构。Used to +动词原形表示过去经常、以前常常,只用于过去式中,用来表示现在已不存在的习惯或状态。例如:They used to play football together.他们过去常在一起蹋足球。(现在不在一起踢了)2.used to的疑问形式和否定形式为Did you use to…?和I didn’t use to… 也可以用Used you to…?和I used not to…但现在多使用前者。例如:Did you used to swim in the river? 你过去常在河里游泳吗?I didn’t use to play the piano. 我以前并不经常弹钢琴。教学目标一、学习目标(Language Goal) 1.学会陈述自己过去常做的事情。2.学会陈述自己过去的爱好等。3.能够表达自己现在和过去在外表、性格、娱乐等方面的变化。4.能够表达朋友、家人等现在和过去的变化。二、语言结构(Language Structures) 1.I used to be short when I was young. 我年轻时个子很矮。 2. —Did you use to have straight hair? 你过去是直发吗?—Yes, I did. 是的。 3. —Did you use to play the piano? 你过去弹钢琴吗?—No, I didn’t. 不,我不弹。 4.I used to be afraid of dark. 我过去害怕黑暗。 5.I’m terrified of the snakes. 我害怕蛇。

先让学生自己总结,然后互相交流,得出结论。解一元一次方程,一般要通过去分母,去括号,移项,合并同类项,未知数的系数化为1等步骤,把一个一元一次方程“转化”成x=a的形式。解题时,要灵活运用这些步骤。板书:解一元一次方程一般步骤:1、 去分母-----等式性质22、 去括号----去括号法则3、 移项----等式性质14、 合并同类项----合并同类项法则5、 系数化为1.----等式性质2【课堂练习】练习:解下列一元一次方程解方程: (2) ;思路点拔:(1)去分母所选的乘数应是所有分母的最小公倍数,不应遗漏。(2)用分母的最小公倍数去乘方程的两边时,不要漏掉等号两边不含分母的项。(3)去掉分母后,分数线也同时去掉,分子上的多项式用括号括起来。回顾解以上方程的全过程,表示了一元一次方程解法的一般步骤,通过去分母—去括号—移项—合并同类项—系数化为1等步骤,就可以使一元一次方程逐步向着 =a的形式转化。
小明说:“我姐姐今年的年龄是我去年的年龄的2倍少6,”已知姐姐今年20岁,问小明今年几岁?若取小明今年为x岁,则依据下面的等量关系式列方程:姐姐今年的年龄=小明去年年龄的2倍-6.得2(x-1)-6=20.例5解方程-3(x+1)=9总结:根据乘法分配律和去括号法则(括号前面是“+”号,把“+”号和括号去掉,括号内各项都不改变符号;括号前面是“-”号,把“-”号和括号去掉,括号内各项都改变符号)去括号时要注意:1、 不要漏乘括号内的任何一项;2、若括号前面是“-”号,记住去括号后括号内各项都变号.习题训练:解方程,如课本P122练一练1,P113练一练2等.思维拓展,解简单的应用题,如课本P123练一练3或补充一些题,如含小括号、中括号、大括号的方程(这方面课本安排几乎没有,只限浅显问题,教师不必深究)
两道例题,第一道题师生共同分析,第二道题学生自己分析。部分学生在运用方程解答问题时,等量关系的寻找还是有困难,规范解题不够合理,仍需在作业过程中教师给予适当的指导。四、课堂小结这节课我们学习了有关打折销售的知识,其实类似的问题我们小学也遇到过,今天在分析实际问题时又用到了列表法,通过这节课的学习,谈谈你在知识方面的收获。提示学生通过对《日历中的方程》《我变高了》以及本节《打折销售》学习还有以往经验,让学生分组讨论,用一元一次方程解决实际问题的一般步骤是什么?目的:让学生进一步体会方程的作用,这里教师又提到学生的小学学习,目的是想提示学生,将今天的方程解法与小学学过的算术方法相对比。此活动的目的是使学生不再处于被动状态,而成为积极的发现者。
由②得y=23x+23.在同一直角坐标系中分别作出一次函数y=3x-4和y=23x+23的图象.如右图,由图可知,它们的图象的交点坐标为(2,2).所以方程组3x-y=4,2x-3y=-2的解是x=2,y=2.方法总结:用画图象的方法可以直观地获得问题的结果,但不是很准确.三、板书设计1.二元一次方程组的解是对应的两条直线的交点坐标;2.用图象法解二元一次方程组的步骤:(1)变形:把两个方程化为一次函数的形式;(2)作图:在同一坐标系中作出两个函数的图象;(3)观察图象,找出交点的坐标;(4)写出方程组的解.通过引导学生自主学习探索,进一步揭示了二元一次方程和函数图象之间的对应关系,很自然的得到二元一次方程组的解与两条直线的交点之间的对应关系.进一步培养了学生数形结合的意识,充分提高学生数形结合的能力,使学生在自主探索中学会不同数学知识间可以互相转化的数学思想和方法.
3.想一想在例1中,(1)点B与点C的纵坐标相同,线段BC的位置有什么特点?(2)线段CE位置有什么特点?(3)坐标轴上点的坐标有什么特点?由B(0,-3),C(3,-3)可以看出它们的纵坐标相同,即B,C两点到X轴的距离相等,所以线段BC平行于横轴(x轴),垂直于纵轴(y轴)。第三环节学有所用.补充:1.在下图中,确定A,B,C,D,E,F,G的坐标。(第1题) (第2题)2.如右图,求出A,B,C,D,E,F的坐标。第四环节感悟与收获1.认识并能画出平面直角坐标系。2.在给定的直角坐标系中,由点的位置写出它的坐标。3.能适当建立直角坐标系,写出直角坐标系中有关点的坐标。4.横(纵)坐标相同的点的直线平行于y轴,垂直于x轴;连接纵坐标相同的点的直线平行于x轴,垂直于y轴。5.坐标轴上点的纵坐标为0;纵坐标轴上点的坐标为0。6.各个象限内的点的坐标特征是:第一象限(+,+)第二象限(-,+),第三象限(-,-)第四象限(+,-)。
第一环节:情境引入内容:(一) 情境1实物投影,并呈现问题:在一望无际的呼伦贝尔大草原上,一头老牛和一匹小马驮着包裹吃力地行走着,老牛喘着气吃力地说:“累死我了”,小马说:“你还累,这么大的个,才比我多驮2个.”老牛气不过地说:“哼,我从你背上拿来一个,我的包裹就是你的2倍!”,小马天真而不信地说:“真的?!”同学们,你们能否用数学知识帮助小马解决问题呢?请每个学习小组讨论(讨论2分钟,然后发言).教师注意引导学生设两个未知数,从而得出二元一次方程.这个问题由于涉及到老牛和小马的驮包裹的两个未知数,我们设老牛驮x个包裹,小马驮y个包裹,老牛的包裹数比小马多2个,由此得方程 ,若老牛从小马背上拿来1个包裹,这时老牛的包裹是小马的2倍, 得方程: .
意图:课后作业设计包括了三个层面:作业1是为了巩固基础知识而设计;作业2是为了扩展学生的知识面;作业3是为了拓广知识,进行课后探究而设计,通过此题可让学生进一步认识勾股定理的前提条件.效果:学生进一步加强对本课知识的理解和掌握.教学设计反思(一)设计理念依据“学生是学习的主体”这一理念,在探索勾股定理的整个过程中,本节课始终采用学生自主探索和与同伴合作交流相结合的方式进行主动学习.教师只在学生遇到困难时,进行引导或组织学生通过讨论来突破难点.(二)突出重点、突破难点的策略为了让学生在学习过程中自我发现勾股定理,本节课首先情景创设激发兴趣,再通过几个探究活动引导学生从探究等腰直角三角形这一特殊情形入手,自然过渡到探究一般直角三角形,学生通过观察图形,计算面积,分析数据,发现直角三角形三边的关系,进而得到勾股定理.
