三年级语文上册第4单元11第八次第1课时教案苏教版
11 第八次古代苏格兰王子布鲁斯带领军队英勇抗击外国侵略军,但屡战屡败,几乎丧失信心。
后来,他看到蜘蛛结网的过程重新燃起了信心,经过第八次抵抗,终于赶跑了外国侵略军。
课文主要是布鲁斯王子的信心的变化,其中受“蜘蛛织网”得到的启发,起到了至关重要的作用,从而能够弄懂布鲁斯成功的原因,体会布鲁斯不懈斗争的精神。
1.学会本课的生字、新词,结合文本内容理解,并能灵活运用;积累多音字“几”“磨”;能正确、流利地朗读课文,理清文章的脉络。
2.在熟读课文的基础上,抓住关键词句理解课文内容,重点读懂第3、4自然段,理解“第八次”成功蕴含的意义:面对困难,坚持不懈,有志者事竟成。
3.体会“几乎”“终于”等词语在表达效果上的不同,并借助这两个词语感受布鲁斯的心理变化,发挥想象,完成课后第4题。
【重点】学习用提取关键词的方法概括每个自然段的意思,进而理清故事的起因、经过、结果,能按照事情发展的顺序有条理、完整地概括文章的主要内容,掌握读懂全文的方法。
【难点】按事情发展的顺序条理、完整地概括故事的主要内容。
1.走进人物的内心,体会人物精神。
布鲁斯的内心变化大:信心因七次大败而几乎失去——信心从蜘蛛结网中重新找回——信心让其鼓起斗志,赶跑外国侵略军。
教学中,教师要引导学生体会布鲁斯不同时期的内心。
如:七次大败后,“布鲁斯唉声叹气、几乎失去信心”,此时可让学生想象人物的内心,并进行有感情的朗读;又如:布鲁斯在看完蜘蛛第八次织网成功后“感动极了。
(他)猛地跳起来,喊道:‘我也要干第八次!’”再次想象布鲁斯的内心,再次进行有感情的朗读,人物的精神也就感受到了。
而课后“练习4”的完成也就水到渠成了。
2.布鲁斯这一位王子的“英勇”形象可以在八次战斗中体会:七次大败几乎失去信心但没失去;从蜘蛛结网中重新找回信心,直至鼓起斗志,赶跑外国侵略军。
蜘蛛能成功进行第八次织网,给了布鲁斯巨大的震撼,这种震撼来自蜘蛛的屡战屡败却屡败屡战的精神,这也是布鲁斯的精神所在。

11减几教案-2
11减几一、教学目标1、知识与技能:使学生初步感悟11减几的计算方法，理解掌握“破十法”。
2、过程与方法：引导学生经历11减几算理的构建过程。
3、情感态度价值观：让学生体验11减几计算方法的多样化，用自己喜欢的方法计算。
二、教学重难点构建“破十法”的表像，理解算理三、教具准备小棒，计算卡片，PPT课件四、教学过程（一）复习导入师：孩子们喜欢玩游戏吗？今天老师带你们到数学王国玩一玩闯关游戏，你准备好了吗？第一关：计算卡片抢答（要求说出计算过程）18-2= 16-5= 17-4= 19-8= 14-3= 11-3=师：前面的计算孩子们都说得很好，为什么最后一个就有困难了呢？11-3还能用前面的方法来计算吗？为什么？这节课我们就一起来学习个位不够减的减法——11减几。
（板书课题）（二）探究新知第二关:文具迷宫（一）教学例一1、获取数学信息，提出问题师：你能从图中获取哪些数学信息？根据这些数学信息，你能提出什么数学问题？2、独立思考，列出算式师：11-2为什么要用减法计算呢？3、动手操作，探究算法师：怎样从1捆零1支铅笔中拿出2只铅笔？请同学们用小棒代替铅笔摆一摆，拿一拿，算一算还剩几根。
4、汇报交流，明确算法生1;把一捆小棒打开变成10根，先拿走单独的一根，再从10根里拿一根还剩9根。
生2：把一捆小棒打开变成10根，先从10根里面拿走2根还剩8根，再把剩下的一根合起来就是9根。
师：为什么要打开一捆小棒，打开一捆小棒在算式中怎样表示？重点引导学生明白算理：个位上不够减，把十位1个十变成10个一再减，先算10-2=8，再算8+1=9。
小结：像这种个位不够减，把十位1个十变10个一再减的方法叫“破十法”。
师：还有其他的方法吗？生1：倒着数，10，9。
生2：做减法想加法：想2+9=11，所以11-2=9。
5、总结归纳，优化算法第二关：勇闯难关（二）教学例21、看图说数学信息，列出算式。
2、用小棒摆一摆，把摆的过程和同桌说一说。
