人教版新目标初中英语八年级下册It’s a nice day, isn’t it教案2篇
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好！欢迎你！请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢？“噢，不！”与陌生人谈话太困难了。但是这也很有意思，并且你还能交到朋友。你该怎么做呢？闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员，不是吗？”“我希望自己能认识她，你呢？“今年的雨水很多，不是吗？”反意疑问句是一种礼貌用语。为了使得谈话成功，你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧，下次在英语课上，你会发现与大家展开谈话是一件很容易的事情，不信我们来试试。)

北师大初中八年级数学下册变形后提公因式因式分解教案
(3)分解因式：1＋x＋x(x＋1)＋x(x＋1)2＋…＋x(x＋1)n(n为正整数)．解析：(1)根据已知计算过程直接得出因式分解的方法即可；(2)根据已知分解因式的方法可以得出答案；(3)由(1)中计算发现规律进而得出答案．解：(1)因式分解的方法是提公因式法，共应用了3次；(2)分解因式1＋x＋x(x＋1)＋x(x＋1)2＋…＋x(x＋1)2015，需应用上述方法2016次，结果是(1＋x)2015；(3)1＋x＋x(x＋1)＋x(x＋1)2＋…＋x(x＋1)n＝(1＋x)n＋1.方法总结：解决此类问题需要认真阅读，理解题意，根据已知得出分解因式的规律是解题关键．三、板书设计1．提公因式分解因式的一般步骤：(1)观察；(2)适当变形；(3)确定公因式；(4)提取公因式．2．提公因式法因式分解的应用本课时是在上一课时的基础上进行的拓展延伸，在教学时要给学生足够主动权和思考空间，突出学生在课堂上的主体地位，引导和鼓励学生自主探究，在培养学生创新能力的同时提高学生的逻辑思维能力.
北师大初中八年级数学下册直接提公因式因式分解教案
解析：(1)首先提取公因式13，进而求出即可；(2)首先提取公因式20.15，进而求出即可．解：(1)39×37－13×91＝3×13×37－13×91＝13×(3×37－91)＝13×20＝260；(2)29×20.15＋72×20.15＋13×20.15－20.15×14＝20.15×(29＋72＋13－14)＝2015.方法总结：在计算求值时，若式子各项都含有公因式，用提取公因式的方法可使运算简便．三、板书设计1．公因式多项式各项都含有的相同因式叫这个多项式各项的公因式．2．提公因式法如果一个多项式的各项有公因式，可以把这个公因式提到括号外面，这种因式分解的方法叫做提公因式法．本节中要给学生留出自主学习的空间，然后引入稍有层次的例题，让学生进一步感受因式分解与整式的乘法是逆过程，从而可用整式的乘法检查错误．本节课在对例题的探究上，提倡引导学生合作交流，使学生发挥群体的力量，以此提高教学效果.
北师大初中九年级数学下册商品利润最大问题2教案
（8）物价部门规定，此新型通讯产品售价不得高于每件80元。在此情况下，售价定为多少元时，该公司可获得最大利润？最大利润为多少万元？若该公司计划年初投入进货成本m不超过200万元，请你分析一下，售价定为多少元，公司获利最大？售价定为多少元，公司获利最少？三、小练兵：某商场经营某种品牌的童装，购进时的单价是60元．根据市场调查，销售量y（件）与销售单价x（元）之间的函数关系式为y= –20 x +1800.（1）写出销售该品牌童装获得的利润w（元）与销售单价x（元）之间的函数关系式；（2）若童装厂规定该品牌童装销售单价不低于76元，不高于78元，那么商场销售该品牌童装获得的最大利润是多少元？（3）若童装厂规定该品牌童装销售单价不低于76元，且商场要完成不少于240件的销售任务，那么商场销售该品牌童装获得的最大利润是多少元？
北师大初中九年级数学下册二次函数与一元二次方程1教案
解：(1)设第一次落地时，抛物线的表达式为y＝a(x－6)2＋4，由已知：当x＝0时，y＝1，即1＝36a＋4，所以a＝－112.所以函数表达式为y＝－112(x－6)2＋4或y＝－112x2＋x＋1；(2)令y＝0，则－112(x－6)2＋4＝0，所以(x－6)2＝48，所以x1＝43＋6≈13，x2＝－43＋6<0(舍去)．所以足球第一次落地距守门员约13米；(3)如图，第二次足球弹出后的距离为CD，根据题意：CD＝EF(即相当于将抛物线AEMFC向下平移了2个单位)．所以2＝－112(x－6)2＋4，解得x1＝6－26，x2＝6＋26，所以CD＝|x1－x2|＝46≈10.所以BD＝13－6＋10＝17(米)．方法总结：解决此类问题的关键是先进行数学建模，将实际问题中的条件转化为数学问题中的条件．常有两个步骤：(1)根据题意得出二次函数的关系式，将实际问题转化为纯数学问题；(2)应用有关函数的性质作答．
北师大初中九年级数学下册解直角三角形1教案

首先请学生分析：过B、C作梯形ABCD的高，将梯形分割成两个直角三角形和一个矩形来解．教师可请一名同学上黑板板书，其他学生笔答此题．教师在巡视中为个别学生解开疑点，查漏补缺．解：作BE⊥AD，CF⊥AD，垂足分别为E、F，则BE=23m．在Rt△ABE中，∴AB=2BE=46(m)．∴FD=CF=23(m)．答：斜坡AB长46m，坡角α等于30°，坝底宽AD约为68.8m．引导全体同学通过评价黑板上的板演，总结解坡度问题需要注意的问题：①适当添加辅助线，将梯形分割为直角三角形和矩形．③计算中尽量选择较简便、直接的关系式加以计算．三、课堂小结：请学生总结：解直角三角形时，运用直角三角形有关知识，通过数值计算，去求出图形中的某些边的长度或角的大小．在分析问题时，最好画出几何图形，按照图中的边角之间的关系进行计算．这样可以帮助思考、防止出错．四、布置作业
北师大初中九年级数学下册利用三角函数测高2教案
问题2、如何用测角仪测量一个低处物体的俯角呢?和测量仰角的步骤是一样的，只不过测量俯角时，转动度盘，使度盘的直径对准低处的目标，记下此时铅垂线所指的度数，同样根据“同角的余角相等”，铅垂线所指的度数就是低处的俯角.活动三：测量底部可以到达的物体的高度.“底部可以到达”，就是在地面上可以无障碍地直接测得测点与被测物体底部之间的距离.要测旗杆MN的高度，可按下列步骤进行：(如下图)1.在测点A处安置测倾器(即测角仪)，测得M的仰角∠MCE=α.2.量出测点A到物体底部N的水平距离AN＝l.3.量出测倾器(即测角仪)的高度AC＝a(即顶线PQ成水平位置时，它与地面的距离).根据测量数据，就能求出物体MN的高度.在Rt△MEC中，∠MCE=α，AN=EC=l，所以tanα= ，即ME=tana·EC＝l·tanα.又因为NE＝AC＝a，所以MN＝ME+EN＝l·tanα+a.
