人教版新课标小学数学二年级下册用乘除法两步计算解决问题说课稿
例2是面包房买卖面包的情境。解决问题的重点是学会使用小括号列综合算式，并了解小括号的作用。通过学生熟悉的购买面包的情境，解决“还剩多少个”这个实际问题。仍然可以引导学生从不同的角度思考问题，启发列式为54-8-22或为54-（8+22）。第二种解法的综合算式，教材中特别强调“如果写成一个算式，应该使用小括号”，并明确“计算时先算小括号里面的”。因为是初次在列式时需要使用小括号，如果学生产生疑问，教师可组织学生通过回顾旧知，利用现实情境，明确使用小括号的必要性及使用方法。教学例2时可以采用与例1相似的教学方式。首先让学生观察下页图，也可以利用电教媒体创设情境，由学生提出问题，并启发学生思考如何解决。让学生充分交流研讨，畅谈自己的想法，然后着重说明解决问题的思路。列式计算时可以先分步列式，同时强调两种列式方法的内在联系，列综合算式时着重说明使用小括号的目的。
人教版新课标小学数学二年级下册万以内的加法和减法（一）整理和复习说课稿
三、估算度的把握。《标准》在计算教学方面强调的内容之一是重视估算，培养估算意识。我们认为重视估算，就是对学生数感的培养，具体体现在能估计运算的结果，并对结果的合理性作出解释。本节课的设计就是让学生在具体情境中，学会两种估算方法，结合具体情况作出合理解释。四、教会学生单元整理与复习的方法，使学生终身受益。我们知道授人以渔而非鱼的道理。在本节课中，老师设计了引导学生学会整理与复习的方法，如：带着问题看书，将算式分类、归纳、总结出本单元所学内容，计算方法，注意地方，最后进行有针对性的练习。如果我们的老师从小就有意识地对学生进行学习方法的培养，学生将终身受益。我想我们教学研讨活动就是为了实现教育的最高境界：今天的教是为了明天的不教。
人教版新课标小学数学五年级下册假分数化成整数或带分数说课稿2篇
一、说教材（一）教材简析《假分数化成整数或带分数》是小学数学五年级（下册）第六单元中的内容。本节内容安排了两个例题。这部分内容是在学生掌握了假分数的意义后，进一步学习把假分数化成整数或带分数，有利于以后进行分数计算打下坚实的基础。（二）教学目标根据教材编排特点，我确定以下教学目标：1、知道带分数是假分数，是整数与真分数合成的数。2、会把假分数化成整数或带分数。3、使学生经历假分数化成整数或带分数的探索过程，进一步发展数感。4、培养良好的学习习惯，树立学好数学的信心。（三）教学重、难点会把假分数化成整数或带分数。二、说教法、学法通过这一环节的教学，把假分数化成整数或带分数时，先要让学生根据假分数的含义进行思考。在这个基础上，再启发学生根据分数与除法的关系计算出结果，并把用不同方法求得的结果进行比较，认识到每种方法都是有道理的。
人教版新课标小学数学五年级下册整数加法的运算定律推广到分数加法说课稿
（一）教学内容：我说课的内容是第5单元中内容，（二）教材地位：加法是数学中最基本的运算之一。从教材的纵向联系来看，几年前已学过整数加法和小数加法，以及加法的运算定律，知道它不仅适用于整数加法，而且也适用于小数加法。那么是否也适用于现在所学习的分数加法呢？这就是我们这节课要研究的问题，当然，结果是肯定的。通过本课的学习，将整数加法的运算定律推广到分数加法，可使学生对加法的认识从感性上升到理性。为后面学习分数加法的简便计算打好基础，同时也为学习小数、分数混合运算奠定基础。其次，将整数加法的运算定律推广到分数加法，也拓展了加法运算定律的使用范围，丰富其内涵。而且加法运算定律字母表示形式，为以后代数知识的学习奠定了初步基础。
人教版新课标小学数学五年级下册同分母分数加减混合运算说课稿
4、简单小结，内化知识引导学生总结出学习的课题（教师板书），学生再明确表达出“同分母分数加减混合运算的顺序与证书加减混合运算的顺序完全相同，计算方法与同分母分数加减法的计算方法相同，即分母不变，分子相加减。注意能月份的一定要约成最简分数为止。”，（三）巩固练习、拓展应用1、基础练习2、引申练习3、解决实际问题 【精心设计练习，既有与例题程度相当的“保底”题，又有与生活密切相关的变式题，拓展思维，培养创新意识，展现数学的应用价值，让学生体会到学习数学有用，生活处处离不开数学。同时适时进行环保教育和爱国主义教育，起到了教书育人的作用。】五、说板书设计此板书力图板书的简洁美，能突出教学的重难点，提示了方法过程。

新人教版高中英语必修2Unit 1 Cultural Heritage-Discovering Useful Structure教案一
This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本节语法思考：定语从句在复合句中的作用是什么？ 关系词有哪些？定语从句在复合句中的作用相当于形容词，它在句中作定语修饰名词或代词。他们在先行词和定语从句之间起到联系作用，同时在意义上代表先行词并在定语从句中担任一个成分。被定语从句所修饰的词称先行词，定语从句一般放在先行词的后面。
