人教版新课标小学数学二年级上册两位数减两位数（不退位减）说课稿2篇
说教材：(1)教学内容：人民教育出版社出版的九年义务教育六年制小学数学教科书第三册中的第16—17页的例1及“做一做”，练习三1、2、3、4、题。(2)教材分析（教材的前后联系，地位作用及编排意图）：两位数减两位数是学生学习笔算减法的开始，也是以后学习多位笔算减法的基础。由于笔算减法是在口算减法的基础上进行教学的，所以教材先安排了口算整十数减整十数、两位数减整十数、两位数减一位数的复习，为理解笔算做好准备。教材由两位数减一位数的不退位减法口算引出两位数减一位数的不退位减法的笔算。说明这种口算题也可以写成竖式，用笔算。然后，对照直观图说明计算时要把相同数位对齐，从个位减起的计算顺序。(3)教学目标：根据教材的编排意图以及学生的实际，我确定本课的教学目标是：使学生理解笔算两位数减两位数的算理，掌握竖式的写法和计算方法，并能正确的笔算。培养学生知识迁移的能力和口头表达能力，培养学生仔细计算的良好学习习惯。
人教版新课标小学数学二年级上册两位数减两位数（退位减）说课稿2篇
一、说教材1、教学内容本节课是义务教育课程标准实验教材人教版小学数学第三册１８至１９页的内容。它是在学生学习了20以内的退位减法、两位数减一位数和两位数减整十数以及两位数减两位数的不退位减法笔算的基础上学习的。它是以后学习多位数减法的重要基础。2、教学目标（1）、知识目标：使学生在理解算理的基础上初步掌握两位数退位减法的计算方法，并能正确的进行计算。（2）、技能目标：培养学生的动手操作能力，发展学生的思维和语言表达能力。（３）、情感目标：通过情景的创设，培养学生的爱国之情，同时让学生在自主探索算法的基础上体验到成功的喜悦。3、教学重点：本节课的重点是理解笔算两位数退位减的算理，能正确用竖式计算。4、教学难点：理解两位数减两位数退位减法的算理。

二、说教学目标1、结合具体情境进一步理解加减法的意义，能正确口算得数是百以内数的两位数加减法。2、能利用所学知识，在教师的指导下提出并解决简单的实际问题，了解同一问题可以用不同的方法解决。3、经历与他人交流各自计算方法的过程，体验解决问题策略的多样性，感受学数学、用数学的乐趣。三、说教法、学法教法：为了使学生掌握好百以内的两位数加减两位数的口算这部分知识，达到以上教学目的，突破以上教学重难点，我采用了迁移法、引导法、讲解法、联系法、自主探索法来进行教学。学法：通过本课的学习，使学生学会利用旧知构建新知的方法、合作探究的方法，调动学生主动探索的积极性。四、说教学过程（一）创设情景、导入新课1、谈话：同学们，大千世界无奇不有。我们所处的人类的社会是由一个个担任不同工作的人所组成的，而和我们生活密切相关的蜜蜂也跟人类一样，它们生活在一个蜜蜂王国里，今天我们就一起到那里了解一下蜜蜂的生活吧。
人教版新课标小学数学三年级下册两位数乘两位数乘法估算说课稿2篇
当学生说出估算思路时，老师可以及时适当进行赏识性的表扬。与此同时，教师对各种估算方法都不急于评价，而是积极引导学生采用多种算法。在刘兼教授的访谈录中，曾经有这么一句话：在提倡算法多样性的同时，老师要不要提出一种最好的解法呢？所谓最好的方法，要和学生的个性结合起来，没有适合全体学生的方法。每个学生的学习方式、思维方式都是独特的，我们要尊重学生自己的选择，不能以一个或一批学生的思维准则来规定全体学生必须采用的所谓最好的方法。因此，教学中我是这样引导学生的：你喜欢用哪一种方法？并说说你喜欢的理由。这样不仅尊重了学生个性的思维方法，还培养了学生的个性发展。探究新知后，我安排有层次性的练习，让学生在练习中巩固估算方法，培养估算意识，增强估算信心。（三）、巩固提高1、基本练习“学以致用”，学习新知识后的练习是学生内化知识的主要环节，也是学生巩固估算方法的环节。
人教版新课标小学数学五年级上册从不同角度观察两个物体说课稿2篇
自主探究法：教学中强调以学生为主体，强调学生参与知识的形成过程，始终做到为学生提供充足的学习素材、创设充分学习的空间、时间，让学生自主探究，体验知识形成的过程，培养主动探究的能力。观察法：例1观察物体教学中的观察是很好的学习方法。例如，教学例1时，观察目的明确。教师通过让学生观察长方体物体学会从不同角度观察物体的方法。这一安排不仅给学生独立思考的机会，而且教给学生观察的思维方法。四、说教学程序在提出问题中，引发学生思考；在自主探索中，激发学生创新思维；在展示交流中，感受学生的个性；在总结陈述中，体验成功的乐趣；在联想记忆中进一步发挥学生的创造才能。在设计这节课时，我在尊重教材的基础上，力求体现新课标的新理念、新思想，导学案中设计了以下几个教学环节：
人教版新课标小学数学四年级下册整数加法运算定律推广到小数说课稿2篇
1．揭示课题那么，这个运算定律是否对分数加法也适用呢？现在我们就来研究这个问题。板书课题：整数加法运算定律推广到分数加法。2．研究运算定律对分数加法的适用性出示式题：提问：上面每组算式的左右两边有什么关系？得数是否相等？先指名学生练习，算出得数后，再引导学生观察。提问：这两组试题有何共同之处？组织学生开展小组讨论，共同概括总结出他们的共同点，得出规律性的认识，从而使学生体会到整数加法运算定律，对分数加法同样适用。通过讨论明确：加法的交换律、结合律中的数，既包括了整数，又包括了小数和分数。【设计意图】通过具体的实践活动，直观感知了加法运算定律同样也适用于分数加法。这种通过自己实践得来的东西，学生理解得更透，掌握得更牢。
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。

北师大版初中数学八年级下册一元一次不等式与一次函数说课稿2篇
由于任何一个一元一次不等式都能写成ax+b>0（或<0）的形式，而此式的左边与一次函数y=ax+b的右边一致，所以从变化与对应的观点考虑问题，解一元一次不等式也可以归结为两种认识：⑴从函数值的角度看，就是寻求使一次函数y=ax+b的值大于（或小于0）的自变量x的取值范围。⑵从函数图像的角度看，就是确定直线y=ax+b在x轴上（或下）方部分所有的点的横坐标所构成的集合。教学过程中，主要从以上两个角度探讨一元一次不等式与一次函数的关系。1、“动”―――学生动口说，动脑想，动手做，亲身经历知识发生发展的过程。2、“探”―――引导学生动手画图，合作讨论。通过探究学习激发强烈的探索欲望。3、“乐”―――本节课的设计力求做到与学生的生活实际联系紧一点，直观多一点，动手多一点，使学生兴趣高一点，自信心强一点，使学生乐于学习，乐于思考。4、“渗”―――在整个教学过程中，渗透用联系的观点看待数学问题的辨证思想。

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
