（3）教师在黑板上话好直线，在相应的点上用小图片代表大树和学生，在问怎样用数表示这些学生和大树的相对位置关系？（让学生把直线上的点和正负数对应起来。（4）学生回答，教师在相应点的下方标出对应的数，再让学生说说直线上其他几个点代表的数，让学生对数轴上的点表示的正负数形成相对完整的认识。（5）总结：我们可以像这样在直线上表示出正数、0和负数，像这样的直线我们叫数轴。（6）引导学生观察：A、从0起往右依次是？从0起往左依次是？你发现什么规律？B、在数轴上分别找到1.5和-1.5对应的点。如果从起点分别到.5和-1.5处，应如何运动？（7）练习：做一做的第1、2题。（二）教学例4：1、出示未来一周的天气情况，让学生把未来一周每天的最低气温在数轴上表示出来，并比较他们的大小。
人教版新课标小学数学六年级下册比例教案
一、回顾旧知，复习铺垫1、上节课我们学习了一些比例的知识，谁能说一说什么叫做比例？比例的基本性质是什么？应用比例的基本性质可以做什么？2、判断下面每组中的两个比是否能组成比例？为什么？6:3和8:4 : 和 :3、这节课我们继续学习有关比例的知识，学习解比例。（板书课题）二、引导探索，学习新知1、什么叫解比例？我们知道比例共有四项，如果知道其中的任何三项，就可以求出这个比例中的另外一个未知项。求比例中的未知项，叫做解比例。解比例要根据比例的基本性质来解。2、教学例2。（1）把未知项设为X。解：设这座模型的高是X米。（2）根据比例的意义列出比例：X:320=1:10（3）让学生指出这个比例的外项、内项，并说明知道哪三项，求哪一项。根据比例的基本性质可以把它变成什么形式？3x＝8×15。这变成了什么？（方程。）教师说明：这样解比例就变成解方程了，利用以前学过的解方程的方法就可以求出未知数X的值。

用空间向量研究直线、平面的位置关系（1）教学设计人教A版高中数学选择性必修第一册
二、探究新知一、空间中点、直线和平面的向量表示1.点的位置向量在空间中,我们取一定点O作为基点,那么空间中任意一点P就可以用向量(OP) ?来表示.我们把向量(OP) ?称为点P的位置向量.如图.2.空间直线的向量表示式如图①,a是直线l的方向向量,在直线l上取(AB) ?=a,设P是直线l上的任意一点,则点P在直线l上的充要条件是存在实数t,使得(AP) ?=ta,即(AP) ?=t(AB) ?.如图②,取定空间中的任意一点O,可以得到点P在直线l上的充要条件是存在实数t,使(OP) ?=(OA) ?+ta, ①或(OP) ?=(OA) ?+t(AB) ?. ②①式和②式都称为空间直线的向量表示式.由此可知,空间任意直线由直线上一点及直线的方向向量唯一确定.1.下列说法中正确的是( )A.直线的方向向量是唯一的B.与一个平面的法向量共线的非零向量都是该平面的法向量C.直线的方向向量有两个D.平面的法向量是唯一的答案:B 解析:由平面法向量的定义可知,B项正确.

“深入探究，把握主旨”这一步则是解决教学的重点难点，这里涉及到课文的深层意蕴，学生理解有难度，教师在通过问题引领学生探讨的基础上，还要适时启发、点拨，因为教学时间有限，让学生漫无边际的讨论，可能难以完成预定的教学任务，会使教学过程不完整。至于本文的写作特点的教学视时间而定，有时间可以让学生说一说，没有时间用小黑板出示一下，让学生了解就行，如果时间不够，甚至可以不讲。第三阶段是“延伸练习，巩固提高”。
