北师大初中数学九年级上册正方形的性质1教案
在Rt△ABC中，AC＝AB2＋BC2＝12＋12＝2(cm)，∴FC＝AC－AF＝2－1(cm)，∴BE＝2－1(cm)．方法总结：正方形被对角线分成4个等腰直角三角形，因此在正方形中解决问题时常用到等腰三角形的性质与直角三角形的性质．【类型三】 利用正方形的性质证明线段相等如图，已知过正方形ABCD的对角线BD上一点P，作PE⊥BC于点E，PF⊥CD于点F，求证：AP＝EF.解析：由PE⊥BC，PF⊥CD知四边形PECF为矩形，故有EF＝PC，这时只需说明AP＝CP，由正方形对角线互相垂直平分可知AP＝CP.证明：连接AC，PC，如图．∵四边形ABCD为正方形，∴BD垂直平分AC，∴AP＝CP.∵PE⊥BC，PF⊥CD，∠BCD＝90°，∴四边形PECF为矩形，∴PC＝EF，∴AP＝EF.方法总结：(1)在正方形中，常利用对角线互相垂直平分证明线段相等；(2)无论是正方形还是矩形，经常连接对角线，这样可以使分散的条件集中．

北师大初中七年级数学上册从三个方向看物体的形状教案2
【教学目标】1．经历从不同方向观察物体的活动过程，发展空间观念；能在与他人交流的过程中，合理清晰地表达自己的思维过程．2．在观察的过程中，初步体会从不同方向观察同一物体可能看到不同的图形．3．能识别简单物体的三视图，会画立方体及其简单组合体的三视图．【基础知识精讲】1．主视图、左视图、俯视图的定义从不同方向观察同一物体，从正面看到的图叫主视图，从左面看到的图叫左视图，从上面看到的图叫做俯视图．2．几种几何体的三视图(1)正方体：三视图都是正方形．圆锥的主视图、左视图都是三角形，而俯视图的图中有一个点表示圆锥的顶点，因为从上往下看圆锥时先看到圆锥的顶点，再看到底面的圆．3．如何画三视图 当用若干个小正方体搭成新的几何体，如何画这个新的几何体的三视图？
北师大初中七年级数学上册代数式的求值教案1
（1）请你用代数式表示水渠的横断面面积；（2）计算当a＝3，b＝1时，水渠的横断面面积.解析：（1）根据梯形面积＝12（上底＋下底）×高，即可用含有a、b的代数式表示水渠横断面面积；（2）把a＝3、b＝1带入到（1）中求出的代数式中，其结果即为水渠的横断面面积.解：（1）∵梯形面积＝12（上底＋下底）×高，∴水渠的横断面面积为：12（a＋b）b（m2）；（2）当a＝3，b＝1时水渠的横断面面积为12（3＋1）×1＝2（m2）.方法总结：解答本题时需搞清下列几个问题：（1）题目中给出的是什么图形？（2）这种图形的面积公式是什么？（3）根据公式求图形的面积需要知道哪几个量？（4）这些量是否已知或能求出？搞清楚了这些问题，求解就水到渠成.三、板书设计教学过程中，应通过活动使学生感知代数式运算在判断和推理上的意义，增强学生学习数学的兴趣，培养学生积极的情感和态度，为进一步学习奠定坚实的基础.
北师大初中七年级数学上册代数式的求值教案2
解 由题意可得，今年的年产值为a·(1＋10%) 亿元，于是明年的年产值为a·(1＋10%)·(1＋10%)＝ 1．21a（亿元）．若去年的年产值为2亿元，则明年的年产值为1．21a ＝1．21×2 ＝ 2．42（亿元）．答：该企业明年的年产值将能达到1．21a亿元．由去年的年产值是2亿元，可以预计明年的年产值是2．42亿元．例3 当x＝－3时，多项式mx3＋nx－81的值是10，当x ＝ 3时，求该代数式的值．解 当x＝－3时，多项式mx3＋nx－81＝－27m－3n－81, 此时－27m－3n－81＝10, 所以27m＋3n＝－91．则当x＝3，mx3＋nx－81 ＝( 27m＋3n )－81＝－91－81＝－172．注：本题采用了一种重要的数学思想——“整体思想”．即是考虑问题时不是着眼于他的局部特征，而是把注意力和着眼点放在问题的整体结构上，把一些彼此独立，但实质上又相互紧密联系着的量作为整体来处理的思想方法．
北师大初中七年级数学上册等式的基本性质教案1
方法总结：对等式进行变形，必须在等式的两边同时进行，即同加或同减，同乘或同除，不能漏掉一边，且同加或同减，同乘或同除的数必须相同.探究点二：利用等式的基本性质解方程用等式的性质解下列方程：（1）4x＋7＝3； （2）12x－13x＝4.解析：（1）在等式的两边都减7，再在等式的两边都除以4，可得答案；（2）在等式的两边都乘以6，再合并同类项，可得答案.解：（1）方程两边都减7，得4x＝－4.方程两边都除以4，得x＝－1；（2）方程两边都乘以6，得3x－2x＝24，x＝24.方法总结：解方程时，一般先将方程变形为ax＝b的形式，然后再变形为x＝c的形式.三、板书设计教学过程中，强调学生自主探索和合作交流，通过观察、操作、归纳等数学活动，感受数学思想的条理性和数学结论的严密性.
北师大初中七年级数学上册等式的基本性质教案2
教学目标1、知识目标：掌握等式的性质；会运用等式的性质解简单的一元一次方程。2、能力目标：通过观察、探究、归纳、应用，培养学生观察、分析、综合、抽象能力，获取学习数学的方法。3、情感目标：通过学生间的交流与合作，培养学生积极愉悦地参与数学学习活动的意识和情感，敢于面对数学活动中的困难，获得成功的体验，体会解决问题中与他人合作的重要性。教学重点与难点重点：理解和应用等式的性质。难点：应用等式的性质，把简单的一元一次方程化为“x=a”的形式。教学时数 2课时（本节课是第一课时）教学方法 多媒体教学教学过程（一） 创设情境，复习导入。上课开始，给出思考，（算一算，试一试）能否用估算法求出下列方程的解：（学生不用笔算，只能估算）
北师大初中七年级数学上册普查和抽样调查教案1
判断下面抽样调查选取样本的方法是否合适：（1）检查某啤酒厂即将出厂的啤酒质量情况，先随机抽取若干箱（捆），再在抽取的每箱（捆）中，随机抽取1～2瓶检查；（2）通过网上问卷调查方式，了解百姓对央视春节晚会的评价；（3）调查某市中小学生学习负担的状况，在该市每所小学的每个班级选取一名学生，进行问卷调查；（4）教育部为了调查中小学乱收费情况，调查了某市所有中小学生.解析：本题应看样本是否为简单随机样本，是否具有代表性.解：（1）合适，这是一种随机抽样的方法，样本为简单随机样本.（2）不合适，我国农村人口众多，多数农民是不上网的，所以调查的对象在总体中不具有代表性.（3）不合适，选取的样本中个体太少.（4）不合适，样本虽然足够大，但遗漏了其他城市里的这些群体，应在全国范围内分层选取样本，除了上述原因外，每班的学生全部作为样本是没有必要的.
北师大初中七年级数学上册生活中的立体图形教案1
解析：此题作为一道开放型题，分类的方法非常多，只要能说明分类的理由即可．但要注意：按某一标准分类时，要做到不重不漏，分类标准不同时，分类的结果也就不尽相同．解：本题答案不唯一，如按柱体、锥体、球体分类：(2)(3)(5)和(6)都是柱体，(4)(7)是锥体，(1)是球体．方法总结：生活中常见几何体有两种分类：一种按柱体、锥体、球体分类；一种按平面和曲面分类．探究点二：几何体的形成笔尖画线可以理解为点动成线．使用数学知识解释下列生活中的现象：(1)流星划破夜空，留下美丽的弧线；(2)一条拉直的细线切开了一块豆腐；(3)把一枚硬币立在桌面上用力一转，形成一个球．解析：解释现象关键是看其属于什么运动．解：(1)点动成线；(2)线动成面；(3)面动成体．方法总结：生活中的很多现象都可以用数学知识来解释，关键是要找到生活实例与数学知识的连接点，如第(1)题可将流星看作一个点，则“点动成线”．如图所示，将平面图形绕轴旋转一周，得到的几何体是()
