This section guides students to pay attention to the typical context of vocabulary use, helps students accumulate vocabulary around the key vocabulary of this unit, and uses the learned words and word chunks in different contexts to deeply understand their meaning and usage, so as to achieve the purpose of review and consolidation.The teaching design activities aim to guide students to pay attention to the typical context in which the target vocabulary is used, as well as the common vocabulary used in collocation, so that students can complete the sentence with correct words. In terms of vocabulary learning strategies, this unit focuses on cultivating students' ability to pay attention to collocation of words and to use word blocks to express meaning.For vocabulary learning, it is not enough just to know the meaning of a single word, but the most important thing is to master the common collocations of words, namely word blocks.Teachers should timely guide students to summarize common vocabulary collocation, such as verb and noun collocation, verb and preposition collocation, preposition and noun collocation, and so on.1. Guide students to understand and consolidate the meaning and usage of the vocabulary in the context, 2. Guide the students to use the unit topic vocabulary in a richer context3. Let the students sort out and accumulate the accumulated vocabulary, establishes the semantic connection between the vocabulary,4. Enable students to understand and master the vocabulary more effectivelyGuiding the Ss to use unit topic words and the sentence patterns in a richer context.

四个同学为一个合作小组;每个小组利用教师为其准备的各类三角形,作出它们的高.比一比,看哪一个小组做得最快,发现的结论多. 师生行为:学生操作、讨论,教师巡视、指导,使学生理解【设计意图】通过让学生操作、观察、推理、交流等活动,来培养学生的动手、动脑能力,发展其空间观察.活动结论:1.锐角三角形的三条高都在三角形内; 2.直角三角形的一条高在三角形内(即斜边上的高),而另两条高恰是它的两条直角边; 3.钝角三角形的一条高在三角形内,而另两条高在三角形外.(这是难点,需多加说明) 总之:任何三角形都有三条高,且三条高所在的直线相交于一点.(我们把这一点叫垂心)课堂小结 1.三角形中三条重要线段:三角形的高、中线和角平分线的概念. 2.学会画三角形的高、中线和角平分线.
(一)、创设情景,导入新课摸牌游戏:三位同学持三组牌,指定三位同学分别任意摸出一张,看谁能摸到红牌,他们一定能摸到红牌吗?请手持牌的同学根据自已手中牌的情况,用语言描述一下抽出红牌的情况。总结:在一定条件下,有些事情我们事先能肯定它一定发生,这些事情成为 事件。有些事情我们事先能肯定它一定不会发生,这些事情称为 事件。 事件和 事件统称为确定事件。许多事情我们事先无法肯定它会不会发生,这些事情称为 事件,也称为 事件。
我们不妨将主旨放在“庄生晓梦迷蝴蝶,望帝春心托杜鹃。沧海月明珠有泪,蓝田日暖玉生烟。”二联之前,那么,事情就变得简单起来了:华年如庄生晓梦迷蝴蝶;华年如望帝春心托杜鹃;华年如沧海月明珠有泪;华年如蓝田日暖玉生烟。从课下注释,我们很容易就可以看出,这四句每一句都在用典。因此,我们通过对典故的解读,然后加以整理,将其理顺,似乎就可以完成对诗歌内容的解读;至于什么悼亡、爱情,不妨抛之脑后,毕竟,没有那些其他的主题,也并没有让诗歌失色,而加上这些捉摸不定的主题,只是让诗歌增加了所谓的神秘色彩,徒增阅读难度而已。
3)乘除运算①有理数的乘法法则:(老师给出,学生一起朗读)1. 两数相乘,同号得正,异号得负,并把绝对值相乘;2. 任何数与零相乘都得零;3. 几个不等于零的数相乘,积的符号由负因数的个数决定,当负因数有奇数个数,积为负;当负因数的个数为偶数个时,积为正;4. 几个有理数相乘,若其中有一个为零,积就为零。②有理数的除法法则:(老师提问,学生回答)1. 两个有理数相除,同号得正,异号得负,并把绝对值相除;2. 除以一个数等于乘以这个数的倒数。③关系(老师给出)除法转化为乘法进行运算。
小学五年级的学生应该具备一些生活技能, 学做家常菜是我们生活的必需,是每个,人都应该掌握的生存技能。本主题的目的通过学习做简单的家常菜,引领小学生走进家务劳动,锻炼生活的自理能力和提高适应生活的能力,体会生活和学习的乐趣,激发学生将学校学习和家务劳动密切结合起来,形成积极的生活和学习的态度。本主题安排了“问题与思考”“学习与探究”“实践与体验”总结与交流“拓展与创新”五个环节,从提出问题开始,到探究与体验,最后到学有所用,循序渐进,引导学习走进中式餐饮文化,学做日常生活中的家常菜,掌握劳动的技能和方法,体验做家务劳动带来的快乐和享受,激发学生对家常菜的探究与实践的兴趣,逐步掌握日常生活所需的基本技能,培养热爱劳动、热爱生活的意识。
本节的内容主要是反比例函数的概念教学.反比例函数概念的建立,不能从形式上进行简单的抽象与概括,而是对这些实例从不同角度抽象出本质属性后,再进行概括。教材设计的基本思路是从现实生活中大量的反比例关系中抽象出反比例函数概念,让学生进一步感受函数是反映现实世界中变量关系的一种有效数学模型,逐步从对具体反比例函数的感性认识上升到对抽象的反比例函数概念的理性认识. 同时本节的学习内容,直接关系到本章后续内容的学习,也是继续学习其它各类函数的基础,其中蕴涵的类比、归纳、对应和函数的数学思想方法,对学生今后研究问题、解决问题以及终身的发展都是非常有益的.基于以上分析,本节教学设计是建立在一个个数学活动的基础上,经过对情境理解、本质抽象的积累而形成的.让学生对一类问题情境中两个变量间的关系,在充分经历写表达式,计算函数值和观察函数值随自变量变化规律的过程中,逐步概括形成反比例函数的概念.针对教学实际,我选取了贴学生现实的,有价值的实例“文具店里买学习用品”和“剪面积为定值的长方形纸片”等作为问题情境.

《锦瑟》的主旨颇多,悼亡、恋情、自伤身世,每一种都有其支持者的长篇论述,但其首联中“一弦一柱思华年。”从这个角度来看,似乎将主题定调为对“华年”的追思,似乎更为妥帖。当我们有了一个明确的基调之后,后面几联在解读时就有了一个准确的方向。
(一)知识与能力 1、指导学生基本掌握诵读本诗的要领,培养学生声情并茂、准确传达情感的诵读能力. 2、帮助学生初步了解“初读—精读—悟读—美读”的诗歌鉴赏方法,培养学生鉴赏古典诗歌的能力。(二)、情感态度与价值观 1、走近李白的激情、浪漫、诗性和放达,感受全诗恢宏的气魄。 2、激发学生与文本、文人和文化的亲近之情
