人教版新课标小学数学一年级上册分类教案
教学目标：1．能选择不同的标准对同一类物品进行不同的分类，掌握分类的方法。2．初步感知不同标准分类的意义，体验分类结果在不同标准下的多样性。3．培养学生思维的灵活性和发散性，养成良好的学习、生活习惯。4．培养学生的操作能力、观察能力、判断能力、语言表达能力和合作交流的意识。5．让学生体会到生活中处处有数学，学会用学到的知识解决生活中的实际问题。教学重、难点：重点：选择不同标准分类难点：思维的发散性 关键：在直观中拓展思维的时空教学准备：铅笔、实物卡片、学具袋（各种形状、颜色各异的物品）教学过程：一、观察分析 多重分类1．师出示如书本P39页的铅笔。（1）观察这些铅笔有什么不同？并把它们分分类。（2）四人一小组交流、讨论可以怎么分类？是按什么分的？比比哪一组的分法最多。
人教版新课标小学数学三年级上册测量教案
教学目标1、认识长度单位毫米，建立1毫米的长度概念，会用毫米厘米度量比较短的物体的长度。2、培养学生的估测意识和能3、培养学生的动手实践和合作学习的能力，并感受生活中处处有数学。教学重点：认识长度单位毫米，会用毫米度量物体长度。教学难点：培养学生的估测方法。教学过程一、引言二、估测数学书的长、宽、厚的长度。师：请同学们观察数学书的长、宽、厚，并估一估大约有多长，然后把估测的结果填入下表？估计实际测量数学书的长数学书的宽数学书的厚生1：数学书的长大约是21厘米、宽大约是14厘米、厚有1厘米。师：你是怎么想的？生1：因为1厘米大约有一个指甲长那么长，数学书的长大约就有21个指甲长那么长，数学书的宽有14个指甲长那么长，数学书的厚有1个指甲长那么厚。
人教版新课标小学数学三年级上册四边形教案
教具、学具准备：各种形状的纸、树叶、绳子、直尺、卷尺等。教学过程：一、今天，老师给大家带来了一些物品和平面图形，你们认识吗？（逐一出示）谁知道周长是什么意思？请你具体指一指，你所喜欢的图形的周长是指什么样的长度。（一生指）二、探究求长方形和正方形周长的计算方法长方形和正方形的周长怎么求呢？正方形的周长只要量一条边长，乘4就可以了。（板书：边长×4）如果量出正方形的边长是5厘米，它的周长是多少？5×4＝20（厘米）。长方形的周长呢？量出四条边的长度，加起来就好了。长＋宽＋长＋宽（板书）。如果长是6厘米，宽是4厘米，它的周长就是：6＋4＋6＋4＝20（厘米）。只要量两次就可以了，量一个长再乘2，量一个宽再乘2就行。长×2＋宽×2。即：6×2＋4×2＝20（厘米）。如果让你求长方形的周长，必须要知道什么条件？正方形呢？想清楚了，我们来解决一些实际问题。
人教版新课标小学数学六年级上册圆教案
教学追记：本堂课，在我带领着学生利用教具进行操作，在此基础上，让学生自主发现圆的面积与拼成长方形面积的关系，圆的周长、半径和长方形的长、宽的关系，并推导出圆的面积计算公式。教学环形的面积计算时，我充分放手给学生，让学生通过思考讨论领悟出求环形的面积是用外圆面积减去内圆面积，并引导他们发现这两种算法的一致性，同时提醒学生尽量使用简便算法，减少计算量。圆的周长和面积的练习课教学目标：1、通过教学使学生理解并掌握圆的周长和面积计算方法。2、培养学生分析问题和解决问题的能力，发展学生的空间观念。3、灵活解答几何图形问题。教学重点：认真审题，分辨求周长或求面积。教学过程：一、复习。1、求出下面圆的周长和面积并用彩笔描出周长，用阴影表示出面积。

人教版新目标初中英语八年级下册If you go to the party, you’ll have a great time教案2篇
区分宾语从句、定于从句和状语从句宾语从句和状语从句，都叫做主从复合句。宾语从句主要是中考必考的，是初中阶段必掌握的从句，宾语从句主要是掌握三要素，所谓宾语从句，就是宾语在主从复合句当中充当宾语的一个句子，叫做宾语从句。主句的谓语动词是及物动词，后面如果是词或者是短语的话，是简单句，如果是句子的话，肯定是宾语从句。I know that he good at English.就是宾语从句，三要素，一要素是要注意连词，连词一共学了三类连词，一类连词是that口语当中可以省略，就像刚才说的那一句，I hear he is good at English.还有疑问代词、疑问副词，how where when，疑问代词、疑问副词。还有一类连词weather是否的意思，不是状语从句当中的如果，这一定要和如果区分开，这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序，要用陈述举语序。比如说你家有几口人，我们都说How many people are there in you family?但是这是简单句，一旦说成宾语从句，你可以告诉我你家有几口人吗？Could you tell me how many people there are in you family ?

北师大初中八年级数学下册旋转作图教案
解析：整个阴影部分比较复杂和分散，像此类问题通常使用割补法来计算．连接BD、AC，由正方形的对称性可知，AC与BD必交于点O，正好把左下角的阴影部分分成(Ⅰ)与(Ⅱ)两部分(如图②)，把阴影部分(Ⅰ)绕点O逆时针旋转90°至阴影部分①处，把阴影部分(Ⅱ)绕点O顺时针旋转90°至阴影部分②处，使整个阴影部分割补成半个正方形．解：如图②，把阴影部分(Ⅰ)绕点O逆时针旋转90°至阴影部分①处，把阴影部分(Ⅱ)绕点O顺时针旋转90°至阴影部分②处，使原阴影部分变为如图②的阴影部分，即正方形的一半，故阴影部分面积为12×10×10＝50(cm2)．方法总结：本题是利用旋转的特征：旋转前、后图形的形状和大小不变，把图形利用割补法补全为一个面积可以计算的规则图形．三、板书设计1．简单的旋转作图2．旋转图形的应用教学过程中，强调学生自主探索和合作交流，经历观察、归纳和动手操作，利用旋转的性质作图.

北师大初中七年级数学上册应用一元一次方程——“希望工程”义演教案1
方法总结：解题关键是要读懂题目的意思，根据题目给出的条件，找出合适的等量关系，列出方程再求解.探究点三：工程问题一个道路工程，甲队单独施工9天完成，乙队单独做24天完成.现在甲乙两队共同施工3天，因甲另有任务，剩下的工程由乙队完成，问乙队还需几天才能完成？解析：首先设乙队还需x天才能完成，由题意可得等量关系：甲队干三天的工作量＋乙队干（x＋3）天的工作量＝1，根据等量关系列出方程，求解即可.解：设乙队还需x天才能完成，由题意得：19×3＋124（3＋x）＝1，解得：x＝13.答：乙队还需13天才能完成.方法总结：找到等量关系是解决问题的关键.本题主要考查的等量关系为：工作效率×工作时间＝工作总量，当题中没有一些必须的量时，为了简便，应设其为1.三、板书设计“希望工程”义演题目特点：未知数一般有两个，等量关系也有两个解题思路：利用其中一个等量关系设未知数，利用另一个等量关系列方程
北师大初中七年级数学上册有理数的加减混合运算的实际应用教案
(1)本周哪一天河流水位最高，哪一天河流水位最低，它们位于警戒水位之上还是之下，与警戒水位的距离分别是多少？(2)与上周末相比，本周末河流的水位是上升还是下降了？解析：(1)先规定其中一个为正，则另一个就用负表示．理解表中的正负号表示的含义，根据条件计算出每天的水位即可求解；(2)只要观察星期日的水位是正负即可．解：(1)前两天的水位是上升的，第1天的水位是＋0.20米；第2天的水位是＋0.20＋0.81＝＋1.01米；第3天的水位是＋1.01－0.35＝＋0.66米；第4天的水位是＋0.66＋0.13＝＋0.79米；第5天的水位是0.79＋0.28＝＋1.07米；第6天的水位是1.07－0.36＝＋0.71米；第7天的水位是0.71－0.01＝＋0.7米；则水位最低的是第一天，高于警戒水位；水位最高的是第5天；(2)＋0.20＋0.81－0.35＋0.13＋0.28－0.36－0.01＝＋0.7米，则本周末河流的水位上升了0.7米．方法总结：解此题的关键是分析题意列出算式，用的数学思想是转化思想，即把实际问题转化成数学问题．探究点二：有理数的加减混合运算在生活中的其他应用
