三年级数学课本下册除和 除以的不同？

1、三年级数学课本下册除和 除以的位置不同

2、“除”和“除以”是对除法算式的两种不同读法。想要弄清楚“除”和“除以”，必须先搞懂什么是“除数”和“被除数”。所谓的“除数”，是一个数学概念，指的就是除法算式中除号后面的那个数，如“14÷2”中的“2”就被称为除数。

大班下册雨天的色彩教案？

活动目标：1.欣赏绘本画面，感受作品所呈现的色彩和布局之美。

2.运用涂画、拓印的方式进行大胆的创作，表现雨天之美。活动实录： 一、 谈话导入，让幼儿尝试用涂画的方式表现雨天的天空 1.师：“你们喜欢雨天吗？为什么？” 幼：“不喜欢，因为不能出去玩。”“喜欢，因为可以给车子洗洗澡”…… 2.师：“你们有没有观察过雨天的天空？是什么样子的？” 幼：“黑黑的。”“有的天深，有的天淡。” 师：“哦，你看见了有变化的天空。” 3.师：“老师这里有黑色、白色的颜料，还有水，请你们想办法把天空画出来，时间有规定，五分钟。” 4.（幼儿操作，教师指导） 5.师：“我想问一问，你们是怎么画出来的？用了什么方法？” 幼：“黑的白的加在一起，变成灰色。”…… 师：“原来，白色颜料和黑色颜料在一起会变成灰色，再加水会变淡。” （这一个环节先是让幼儿把自己印象中的雨天的天空用涂画的方法画出来，并且让幼儿在尝试的过程中自己发现，黑色和白色颜料加在一起会变成灰色，加水会变淡，但是我觉得在这个环节中，教师可以选取两个幼儿的画做一个对比，让幼儿发现，水加的多颜色会更淡并且更均匀。） 二、 观看课件，感受作品的色彩之美 1.师：“灰蒙蒙的雨天，你的心情怎么样？有没有什么好听的词形容。” 幼：“心里没有彩虹”“很舒服”“很平静”…… 2.（观看课件《多彩的雨天》） 3.师：“小黄是谁？” 幼：“黄色的雨伞。” 4.师：“它为什么说雨天是鲜艳的呢？你看到了哪些颜色？” 幼：“红色、黄色、蓝色、粉色……” 师：“可以用什么好听的词形容这么多颜色？” 幼：“五颜六色、色彩缤纷。” （这一部分是让幼儿感受灰色的雨天有了那么多五颜六色的伞变的更好看了，让幼儿体会到作品中的色彩之美。教师适当的给了幼儿一些词语，比如“色彩缤纷”） 三、 观察图片，感受作品的布局之美 1.（出示四幅图）师：“你更喜欢哪一张？为什么？” 2.师：“这幅都是伞的画上面都有哪些颜色的伞？你喜欢什么颜色？” 总结：“有的颜色深，有的颜色浅，雨伞铺满了画面，丰富就是一种美。3.师：“你还喜欢哪幅？为什么？” 总结：“雨伞们一个跟着一个走楼梯，有的在一起，有的走在前面，有规律的排列就是一种美。” 4.师：“还有的小朋友喜欢哪幅？为什么？”“谁和谁走在了一起？”（渗透遮挡的概念。） 总结：“有的一起，有的分开，这是一种变化的美。” 5.师：“最后一幅你喜欢吗？为什么？” 总结：“简单也是一种美，红黄蓝是三原色，他们互相拉手，能变出各种颜色。” （这一个环节是让幼儿感受四幅画中不同的布局之美，但是一幅幅分析，花的时间有点久了，幼儿不专注。幼儿的收获很大，虽然不一定能一下子接受，但是，幼儿的美术欣赏能力和表现能力本就是在一个个活动中慢慢积累起来的。）
