2023年鲁班和橹板答案(十篇)
在日常的学习、工作、生活中,肯定对各类范文都很熟悉吧。那么我们该如何写一篇较为完美的范文呢?以下是我为大家搜集的优质范文,仅供参考,一起来看看吧
鲁班和橹板答案篇一
认识橹板首先肯定是从课文中的插图开始的,我利用插图让学生看看橹板,而后从橹板迁移到老艄公的表情,猜猜用这样的橹板来摇船轻松吗?孩子们都可以从图上看出用橹板摇船省力多了!我就要求孩子找出课文写船走得快的句子进行朗读。
在这之前,老艄公并没有这么轻松的,他用什么摇船呢?摇得结果与现在比一比,怎么样呢?让学生从课文中找出句子来读读。学生又进入了第一自然段的学习,我抓住“十分吃力”“满头大汗”这两个词语来体会老艄公的累。鲁班的爱动脑的习惯我是从两个词语来体会的,“盯着”“出神”通过这两个词语的表演与举例,告诉学生只有动脑筋思考才会学好知识,才会有新创造。从“出神”再引出“眼睛一亮”,让学生懂得是什么东西让鲁班有了新的想法,有了新的发明的,学生很自然就想到了是鸭子帮了鲁班的忙。
第三自然段我先用图片让学生认识鸭子的“脚蹼”,然后边说边示范鸭子脚蹼拨水的样子,接着让学生走入情境:“现在你们就是那群小鸭子,你们的手就是脚蹼,快来拨水吧!”学生用手做拨水的样子,同时提醒学生把手并起来会游得更快些(拨与划的区别),学生的兴趣被调动起来,接着提高难度,请学生带上表情,加上动作来读这一小节,一次,两次……学生的情绪高涨,在游戏中将文本的朗读提高到了一个层次。
第四自然段是全文的重点。我接着提出鲁班设计的“橹板”是什么样子,你知道吗?学生在理解第4自然段的基础上通过读、说(先……然后……再……)做等手段认识“橹板”的样子、体验鲁班制作的过程。(鲁班看到鸭子用脚蹼拨水那么轻快,“眼睛一亮,马上找来一根粗木棍”,做橹板的过程用动画的形式放出来,学生在轻松的氛围中明白了橹板的制作过程。接着我又安排了让学生动手制作“橹板”。力力求通过动手让学生记忆“橹板”的形状,体会制作过程,激发学生去动手制作、创作的兴趣。我再提出鲁班为什么要把“橹板”做成这个样子。第三小节讲鸭子在水中用脚蹼拨水的样子,是鲁班发明橹板的关键之处,这里我重点抓着“拨”体会鲁班将“橹板”制作矶成鸭爪样子的原因。
写字是低年级语文教学的一项重要任务,在每一课时都应有写字教学,因此我在教学生字时尽量注意做到加强板书示范,端正学生的写字姿势,加强基本笔画教学,指导运笔。采取多种方法调动学生的主观能动性和写字的积极性。当然,在教学中仍有许多不足,今后还须多多努力,提高教学质量。

鲁班和橹板答案篇三
《鲁班和橹板》是苏教版语文一年级下册第22课。它讲述了我国历史上著名的能工巧匠鲁班受鸭子游泳的启示而发明橹板的故事。课文叙事具体明白,通过朗读要让学生感受到鲁班爱观察、勤思考、能创造的优秀品质。
(友情提醒:查找本课更多资料,请在站内搜索课文题目)
处理第一自然段的时候,我提问:你从哪里看出老艄公很吃力?学生找到了关键词“满头大汗”,指导读好。这里我应该设计一个想像训练:想像老艄公满头大汗是怎样的情景?从而来体会鲁班对艄公的同情。
在处理第二自然段的时候,我是抓住了“盯”这个字,同时让学生说说你还知道哪些词语也是表示“看”的意思?然后出示了一个相关的练习:用“看、望、盯、瞧”填空。这个设计是好的,可是这样一来,就把学生从课文中拉了出来,等到练习完成了,还要再把学生拉进来,就比较麻烦。可以把这个练习放到课堂结束的时候,这样会更好一些。
第三自然段主要是抓住两个象声词和“轻快”来理解鸭子滑行的轻松。
第四自然段重点是抓住“出神”和“眼睛一亮”来体会鲁班思考的认真。鲁班在“出神”,那他此时在看什么呢?再回到前文,他又会想些什么呢?同时如果能抓住前文中的“盯”来理解,进行比较,学生的理解会更深刻一些。
最后,为什么称这个工具为“橹板”?可以让学生说一说。人们为了纪念鲁班发明了这样一个省力的工具,所以起名叫“橹板”。
总结这节课,我应该把重点放在理解课文上。课文是由词语和句子组成的,光理解词语还不行,还要把词语放到特定的语文环境中,为以后的语文教学打下坚实的基础。

鲁班和橹板答案篇五
《鲁班和橹板》是苏教版一年级下册第八单元中的一篇课文。讲述了我国历史上著名的能工巧匠鲁班受鸭子游泳的启示而发明橹板的故事,课文叙事具体明白,通过朗读要让学生感受到鲁班爱观察、勤思考,能创造的优秀品质。
复习时,我设计了两道填充题,让学生填出带拼音的字,并读通句子,这样既复习了上节课学习的7个生字,又回顾了全文的主要内容,在教学第一自然段时,我紧扣“十分吃力”、“满头大汗”,让学生联系生活理解“满头大汗”,从而感受老艄公用竹篙撑船的辛苦,为下文鲁班的“想”作铺垫。第二自然段我紧扣鲁班的动作“两眼盯着”,“默默地想”,让一个孩子上台来做“两眼盯着”的动作,帮助孩子理解“两眼盯着”就是眼睛一动也不动地看着一个地方。在讲解鸭子拨水时,让学生抓住“往后拨水,身子向前”来明白鸭子拨水的轻快,第四小节抓住“眼睛一亮”再现鲁班思考的过程。
课文的第三小节讲鸭子在水中用脚蹼拨水的样子,是鲁班发明橹板的关键之处,这一小节我先用图片让学生认识鸭子的“脚蹼”,然后边说边示范鸭子脚蹼拨水的样子,接着让学生走入情境:“现在你们就是那群小鸭子,你们的手就是脚蹼,快来拨水吧!”学生用手做拨水的样子,同时提醒学生把手并起来会游得更快些,学生的兴趣被调动起来,接着提高难度,请学生带上表情,加上动作来读这一小节,一次,两次……学生的情绪高涨,在游戏中将文本的朗读提高到了一个层次。
课文的第4小节是全文的重点。鲁班看到鸭子用脚蹼拨水那么轻快,“眼睛一亮,马上找来一根粗木棍”,做橹板的过程用视频动画的形式放出来,学生在轻松的氛围中明白了橹板的制作过程。
另外,用“竹篙撑船“的吃力和用“橹板摇船“的轻松学生不易理解,这两种场景学生在生活中几乎没有见过,同样通过视频的演示,学生也能轻而易举地明白两种行船工具的好与次了。
当然,在教学中仍有许多不足,对于字的教学只设计了教学“忽”和“安”两个字,低年级的生字教学是非常重要的,在今后的教学中,我将时刻以《课标》为基准,研读教材,备透学生,把新课程的理念切实用在每一节课上,让学生在轻松、愉悦的氛围中接受知识。

鲁班和橹板答案篇八
《鲁班和橹板》是苏教版一年级下册第八单元第23课。故事讲述了我国历史上著名的能工巧匠、创造发明家鲁班受鸭子游泳的启示而发明橹板的故事,课文叙事具体请楚,我立足于利用朗读、观察、动手操作等方式让学生感受到鲁班爱观察、勤思考、能创造的优秀品质。
第二课时复习,我设计了两道选字填空题,让学生进行同音异形、形似字的比较,并学会使用。在教学第一自然段时,我紧扣"十分吃力"、"满头大汗",让学生联系生活理解"满头大汗",从而感受老艄公用竹篙撑船的辛苦,又让学生体会到隐含的鲁班的要发明“橹板”的原因。第二自然段我紧扣鲁班的动作"两眼盯着","默默地想",让一个孩子上台来做"两眼盯着"的动作,帮助孩子理解“两眼盯着”就是眼睛一动也不动地看着一个地方。在讲解鸭子拨水时,让学生抓住"往后拨水,身子向前"来明白鸭子拨水的轻快,第四小节抓住“眼睛一亮”再现鲁班思考的过程。
课文第4自然段是本文的重点。为了能抓住重点我并没有采用学生习惯的顺序学习的思路。我采用倒叙的方法:
1、 复习第一自然段后提出鲁班最终有没有想出好办法,设计出省力的工具?这个工具叫什么?学生自然会想到到课文的最后去找答案。并给这样的答案:想出好办法,这个工具叫“橹板”。
2、 我接着提出鲁班设计的“橹板”是什么样子,你知道吗?学生在理解第4自然段的基础上通过读、说(先……然后……再……)做等手段认识“橹板”的样子、体验鲁班制作的过程。(强调制作与创作的区别)。
3、 我再提出鲁班为什么要把“橹板”做成这个样子。第三小节讲鸭子在水中用脚蹼拨水的样子,是鲁班发明橹板的关键之处,这里我重点抓着“拨”体会鲁班将“橹板”制作矶成鸭爪样子的原因。
第三自然段我先用图片让学生认识鸭子的“脚蹼”,然后边说边示范鸭子脚蹼拨水的样子,接着让学生走入情境:“现在你们就是那群小鸭子,你们的手就是脚蹼,快来拨水吧!”学生用手做拨水的样子,同时提醒学生把手并起来会游得更快些(拨与划的区别),学生的兴趣被调动起来,接着提高难度,请学生带上表情,加上动作来读这一小节,一次,两次……学生的情绪高涨,在游戏中将文本的朗读提高到了一个层次。
课文的第四自然段是全文的重点。鲁班看到鸭子用脚蹼拨水那么轻快,“眼睛一亮,马上找来一根粗木棍”,做橹板的过程用动画的形式放出来,学生在轻松的氛围中明白了橹板的制作过程。接着我又安排了让学生动手制作“橹板”。力力求通过动手让学生记忆“橹板”的形状,体会制作过程,激发学生去动手制作、创作的兴趣。
朗读教学是贯穿始终的,一开始让学生通过看图片读出老艄公的累,通过朗读感受鲁班在想办法,通过朗读感受鲁班的"眼睛一亮",想出了办法,通过朗读感受一个"嗬"字,体会老艄公摇橹的轻松。
全文抓住鲁班的看——想——看——做展开,在讲解文本中,我在每个小节的过渡时都抓住了这条线索,循循善诱,层层推进,最后到“做”,顺理成章,水到渠成。
当然,在教学中仍有许多不足,对于字的教学只设计了教学“忽”和“安”两个字,低年级的生字教学是非常重要的。同时练习量的不足,没有很好的巩固过程。
鲁班和橹板答案篇九
《鲁班和橹板》这篇课文叙事具体明白,我从“你能说一说橹板和橹板之间的关系吗”导入新课,然后抓住两个主要问题“橹板为什么要发明橹板?鲁班是怎样发明橹板的”引导学生从课文中去寻找答案并展开讨论。我利用以下几点,突破了重难点,使学生在具体形象的环境中很快理解了课文。
课文第四自然段写鲁班受鸭子拨水滑行的启示,终于造出了摇船的新工具,这一段是文章的重点。可是,我们许多学生根本没见过鸭子,也不知道鸭子的脚有什么特别的。于是,我找来鸭子的图片,并且放大它的脚蹼,让学生观察鸭子的脚有什么特别之处,从而帮助学生理解脚蹼的作用。然后我又出示鸭子在河里轻快地游泳的动画,让学生观察:鸭子是怎样游泳的?它游得怎么样?此时,把鸭子轻快游泳与老艄公吃力地摇船相比较,让学生产生与鲁班类似的想法:要是能让老艄公摇船也像鸭子一样轻快就好了。站在鲁班的角度体会他的心路历程,更便于理解课文内容。在鲁班发明了橹板后,我又通过简笔画画出橹板的大体形状,又把橹板和鸭子的腿进行了逐一的对照,使学生更清楚地明白鲁班是根据鸭子的什么发明了橹板,体会鲁班的聪明、能干。
在鲁班发明了橹板后,我又把前后文联系起来,抓住“十分吃力”、“累得满头大汗”、“一摇……嗬……”、“不光……也……”,进行对比,体会这种新工具给艄公带来的好处,感悟鲁班“善于观察,勤于动脑”的品质。
在课文学完后,通过结合上学期《人有两个宝》的学习,以及视频《鲁班发明锯子》理解鲁班的爱思考、爱创造。我又让学生讲讲你还知道关于鲁班或其他人的发明小故事,进一步地体会鲁班等发明家善于观察、善于联想、积极动手尝试的优秀品质。教育学生从小就要养成这样的好习惯。
