2012级初三英语总复习教案数词【使用教材和授课内容】义务教育课程标准试验教材（新目标）Go for it!九年级中考专项复习之数词【教学背景分析】1学生分析：今年我所教的两个班各有学生50人，其中优等生各14人，有一半的学生对英语充满着浓厚的兴趣，但是每班有20来个学生学习英语几乎没有兴趣，成绩很差，两极分化非常严重。2教学手段：本节课以课时学案为主要教学手段，运用洋思中学“先学后教、当堂训练”的教学模式，鼓励帮助学生自主、合作和创新学习。3资料准备：在准备资料时，我精心搜集数词的有关素材，对数词相关知识的系统复习做到心中有数，并从20082011年各省市的中考真题中收集数词的相关试题，以便更好地承载所复习的知识，吸引学生的注意力。4前期教学状况：关于数词的知识，在七年级就已经开始接触了，并且在教学中几乎每节课都要涉及到，在生活中应用更是非常广泛，可见数词的学习尤为重要。其实，在新授课过程中已经反复训练了，因此本课通过一系列的课堂活动进行完整的复习。【教学目标设计】1知识目标：参考2008年至2011年绵阳市四年的中考试题分析考点、钻研考点，使学生们对数词有更准确地把握和认识。1掌握基数词和序数词的构成形式和基本用法。 2熟练掌握时间及日期的基本表达方法。 3掌握日常交际活动中的数词常见用法。 4理解数词的某些特殊用法。5、了解英语数词部分成语和习语的惯用表达法2能力目标：通过听力和回答练习学会用所学的相关知识表达生活中的场景和情感，例如：电话号码、天气温度、时间的表达、数量统计等的使用。3过程与方法：先利用听力测试来检测学生对数词的掌握程度和真实水平，让他们感觉到数词的使用就在身边，就在自己的实际生活中，以便激起学生对数词复习的愿望和激情。然后结合各省市近几年的中考试题有关数词的考查，让学生自己通过分析找到中考考点，从而习得规律。在根据考试规律和认识，展开数词总复习，让学生根据学案的提示，自己动手、动脑去总结归纳和分析，把课堂放开留给学生。最后强化训练，查漏补缺，提升能力，增强信心。4情感态度与价值观：课堂上立足于复习内容，设计了一些能激趣的活动形式，既活跃课堂气氛，有培养学生学英语的兴趣。 【课前准备】 要求学生对所学过的数词作系统归纳。 1基数词的构成和用法 2、和序数词的构成和用法3分数表达法： 4小数表达法：5、百分数的表达 6、倍数表达7、约数表达 8、常用加减法的表达9、时刻表达法 10、数量表示法11 年、月、日时间表达法 12、部分成语和习语的惯用表达法【复习重点】1基数词的构成和用法2、序数词的构成和用法3、时刻表达法4、数量表示法5 年、月、日时间表达法：【教学过程】一、知己篇：考考自己（学生做练习，体会英语数字在日常生活中的运用）1、听力训练A) B) C) A) The No. 7 Middle School.
