If a traffic accident happens and someone is injured, the following steps can be used to treat the injured.In the first place, we should make sure that the accident scene is safe so that we won’t get hurt. We should ask the injured person if he is OK, and see if he is breathing. What’s more, we should check for cuts and wounds. If he is bleeding badly, it is vital that we should try to stop the bleeding by applying pressure to the injury. This is because if a person loses too much blood, he may die. If necessary, take the injured person to the hospital as soon as possible.Do remember: when giving first aid, please be sure to place the person in a recovery position.

教学目标：1．会画直棱柱（仅限于直三棱柱和直四棱柱）的三种视图，体会这几种几何体与其视图之间的相互转化。2. 会根据三视图描述原几何体。教学重点：掌握直棱柱的三视图的画法。能根据三视图描述原几何体。教学难点：几何体与视图之间的相互转化。培养空间想像观念。课型：新授课教学方法：观察实践法一、实物观察、空间想像观察：请同学们拿出事先准备好的直三棱柱、直四棱柱，根据你所摆放的位置经过 想像，再抽象出这两个直棱柱的主视图，左视图和俯视图。绘制：请你将抽象出来的三种视图画出来，并与同伴交流。比较：小亮画出了其中一个几何体的主视图、左视图和俯视图，你认为他画的对不对？谈谈你的看法。拓展：当你手中的两个直棱柱摆放的角度变化时，它们的三种视图是否会随之改变？试一试。
北师大初中数学九年级上册复杂图形的三视图1教案
解析：熟记常见几何体的三种视图后首先可排除选项A，因为长方体的三视图都是矩形；因为所给的主视图中间是两条虚线，故可排除选项B；选项D的几何体中的俯视图应为一个梯形，与所给俯视图形状不符.只有C选项的几何体与已知的三视图相符.故选C.方法总结：由几何体的三种视图想象其立体形状可以从如下途径进行分析：（1）根据主视图想象物体的正面形状及上下、左右位置，根据俯视图想象物体的上面形状及左右、前后位置，再结合左视图验证该物体的左侧面形状，并验证上下和前后位置；（2）从实线和虚线想象几何体看得见部分和看不见部分的轮廓线.在得出原立体图形的形状后，也可以反过来想象一下这个立体图形的三种视图，看与已知的三种视图是否一致.探究点四：三视图中的计算如图所示是一个工件的三种视图，图中标有尺寸，则这个工件的体积是（）A.13πcm3 B.17πcm3C.66πcm3 D.68πcm3解析：由三种视图可以看出，该工件是上下两个圆柱的组合，其中下面的圆柱高为4cm，底面直径为4cm；上面的圆柱高为1cm，底面直径为2cm，则V＝4×π×22＋1×π×12＝17π（cm3）.故选B.

北师大版初中数学八年级下册图形的平移说课稿
1、数数格子，认清方向（完成想想做做第1题）设计意图：本题在于让学生认清平移的方向和距离，感受平移的不同方法。在教学中，让学生自己独立思考完成，自由发言。鼓励学生说出不同的平移方法。2、小试牛刀（完成想想做做第2题）设计意图：本题主要是让学生掌握按要求画平移后的图形。这是本节课的难点。在教学中，先让学生独立画图，教师巡视作图情况，对有困难的学生给予指导。在学生完成作图后，投影部分学生的作品，交流平移的过程与方法。最后在多媒体课件上展示画法。.3、平移的运用(“想想做做”第3题)设计意图：本题在于使学生学会运用平移的知识画平行线，体会平移的价值。（四）课堂小结，升华提高提问：今天你有哪些收获?设计意图：以问题为载体，引领学生对本节课的归来总结。让学生再次理解图形的斜向平移可转换成横向平移和竖向平移。
北师大版初中数学九年级上册图形的放大与缩小说课稿
说教学难点：图形的放大与缩小的原理是“大小改变，形状不变“。针对小学生的年龄和认知特点，教材中“图形的放大与缩小”从对应边的比相等来进行安排，而对应角的不变也是形状不变必备的条件，是学生体会图形的相似所必需的。学生在学习的过程中很有可能会质疑到这一问题。（为什么直角三角形只需要同时把两条直角边放大与缩小？）所以我把“学生在观察、比较、思考和交流等活动中，感受图形放大、缩小，初步体会图形的相似。（对应边的比相等，对应角不变）”做为本节课的难点。说教法、学法：通过直观演示，情景激趣，结合生活让学生形成感性认识；引导学生经过观察、猜想、分析、操作、质疑、小组交流、合作学习、验证等过程形成理性认识。教学过程：（略）

【高教版】中职数学拓展模块：3.2《二项式定理》教学设计
一、定义： ，这一公式表示的定理叫做二项式定理，其中公式右边的多项式叫做的二项展开式；上述二项展开式中各项的系数 叫做二项式系数，第项叫做二项展开式的通项，用表示；叫做二项展开式的通项公式．二、二项展开式的特点与功能1. 二项展开式的特点项数：二项展开式共（二项式的指数+1）项；指数：二项展开式各项的第一字母依次降幂（其幂指数等于相应二项式系数的下标与上标的差），第二字母依次升幂（其幂指数等于二项式系数的上标），并且每一项中两个字母的系数之和均等于二项式的指数；系数：各项的二项式系数下标等于二项式指数；上标等于该项的项数减去1（或等于第二字母的幂指数；2. 二项展开式的功能注意到二项展开式的各项均含有不同的组合数，若赋予a，b不同的取值，则二项式展开式演变成一个组合恒等式．因此，揭示二项式定理的恒等式为组合恒等式的“母函数”，它是解决组合多项式问题的原始依据．又注意到在的二项展开式中，若将各项中组合数以外的因子视为这一组合数的系数，则易见展开式中各组合数的系数依次成等比数列．因此，解决组合数的系数依次成等比数列的求值或证明问题，二项式公式也是不可或缺的理论依据．
