1、云南省二一四学年第 二学期学 科劳动技术班 级五年级教 师（学校）劳动技术学科（五年级下 册）教学计划一、学情分析两个班共有学生108 人。学生情况分析：本学期我担任的五1、五 2 两个教学班，由于我担任这两个班的数学课，所以对学生比较熟悉。学生对劳动技术课还是比较喜欢，他们喜欢动手，喜欢做实验，这对我来说有利于上好本学期的劳动技术课。但是也有极个别的学生上课不认真，比较随便，影响了上课，这学期对这些学生要加强教育。所以，我有信心上好五年级的劳动技术课。二、本册教材分析：这一册教材包括下面一些内容：图形的变换、长方体和正方体的认识、分数的意义和性质、分数的加法和减法、统计、数学广角和综合应用等

2、。其中因数和倍数，长方体和正方体，分数的意义和性质，分数的加法和减法，统计等是本册教材的重点内容。（一）、本册教材的特点：1、优化编排结构，突出数学的文化特色，为培养学生的数感提供丰富素材。2、计算教学内容的编排体现改革的理念，注重培养学生灵活的计算能力，发展学生的数感。3、提供丰富的空间与图形的教学内容，注重实践与探索，促进学生空间观念的发展。4、加强统计知识的教学，使学生的统计知识和统计观念得到进一步提升。5、有步骤地渗透数学思想方法，培养学生数学思维能力和解决问题的能力。6、情感、态度、价值观的培养渗透于数学教学中，用数学的魅力和学习的收获激发学生的学习兴趣与内在动机。（二）、本册教学重

3、点：因数和倍数，长方体和正方体，分数的意义和性质，分数的加法和减法，统计等（三）、本册教学难点：因数和倍数，长方体和正方体三、实施教学的主要措施：1、理解分数的意义和基本性质，会比较分数的大小，会把假分数化成带分数或整数，会进整数、小数的互化，能够比较熟练地进行约分和通分。2、掌握因数和倍数、质数和合数、奇数和偶数等概念，以及2、3、5 的倍数的特征；会求100 以内的两个数的最大公因数和最小公倍数。3、理解分数加、减法的意义，掌握分数加、减法，会解决有关分数加、减法简单实际问题。4、知道体积和容积的意义及度量单位，会进行单位之间的换算，感受有关体积和容积之间的实际意义。5、结合具体情境，探索

4、并掌握长方体和正方体的体积和表面积的计算方法，探索某些实物体积的测量方法。6、能在方格纸上画出一个图形的轴对称图形，以及将简单图形旋转90 度；欣赏生活中的图案，灵活运用平移、对称和旋转在方格纸上设计图案。7、通过丰富的实例，理解众数的意义，会求一组数据的众数，并解释结果的实际意义；四、教学进度周次教学内容课时数备注1 插花1 文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编码:CW6X

20、喷雾器等。4、演示插花步骤：立意构思：也就是在进行艺术创作之前先要确定意图。根据需要确定插花的造型：直立形、倾斜形、下垂形、直上形或对称形。确定花插的形状或大小，也叫打底。根据造型选用确定插入焦点花材，也就是确定视点中心，困此，要选择鲜艳、富有神采形状的花材。另外要有高低的搭配，要具有合谐性。5、请同学们自愿分成小组制作插花：35 人都可以，人数不限。请各小组的同学讨论一下，你们的花想送给谁或想摆放在哪里？你们想选择什么花材？请每组派一名代表到前面来选择插花容器和花材。在大家插花之前，我有个要求：请给作品起出名字，并派一名代表说一下你们的立意构思及寓意。下面就请大家运用自己灵巧的双手来进行你们

21、的创作吧。7、作品展评：请大家把作品放到前面。你们比较喜欢哪个作品？为什么？请作者说一下你的创意吧。8、插花的保鲜。9、插花的注意事项及质量要求。三、小结：同学们的作品都很有想象力和创造性。插花，不是单纯的花草组合，也不是简单的造型，它是融艺术、生活与一体的艺术活动。我相信大家通过花与草的构筑一定会将我们的生活创造的更加美满富有情调。课堂练习家庭作业板书设计教学反思参考资料学 科五年 级(第二册)备课教师授课时间第周月日教学内容电冰箱的使用课时1 课时教学目标通过教学，使学生认识双门电冰箱的结构，并掌握一些使用和保养电冰箱的知识，并能把这些知识运用到生活实际中去。文档编码:CW6X5B10I8

46、持续的滴水在短时间内就会浪费掉不知道多少水费。如何修理水龙头滴水呢？二、教学新知：1、认识普通水龙头的结构（看课本23 页图 2）2、学习普通水龙头漏水修理的步骤方法（看课本24 页的内容及图3，看完后交流）步骤 1：关闭供水，卸下在水龙头把手上面或后面的小螺丝以拆下固定在水龙头主体上的把手。一些螺丝藏在金属按钮、塑料按钮或塑料片下面，这些按钮或塑料片卡入或拧入把手。您只要把按钮打开，就会看到装在顶部的把手螺丝。如果有必要，使用一些像WD-40 规格的渗透润滑油来使螺丝变松。步骤 2：卸下把手，查看水龙头的部件。用大鲤鱼钳或可调扳手取下填密螺母，小心不要在金属上留下划痕。向与您打开水龙头时旋转

47、的同一方向旋转阀芯或轴以把它们拧下来。步骤 3：取下固定垫圈的螺丝。如果有必要，使用渗透润滑油来使螺丝变松。检查螺丝和阀芯，如果有损坏要更换新的。步骤 4：用一个完全相同的新垫圈换掉旧垫圈。与旧垫圈几乎完全匹配的新垫圈一般都可以让水龙头不再滴水。您还要注意到旧垫圈是有一个斜面的还是平的，并且用相同的新垫圈进行更换。只针对冷水设计的垫圈在有热水流过时会剧烈膨胀从而堵塞出水口，使得热水流变慢。有些垫圈在冷热水中都可以工作，但是您要确定您买的用于更换的垫圈与原来的是一模一样的。步骤5：将新的垫圈固定到阀芯上，然后把水龙头中的各部件重新装好。向顺时针方向旋转阀芯。阀芯就位后，把填密螺母重新装上。小心不

48、要让扳手在金属上留下划痕。步骤 6：重新安装把手并把按钮或圆盘装回去。重新开启供水，检查是否还有漏水。3、学习水龙头漏水修理的注意事项 4、水龙头漏水修理的质量要求。课堂练习文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编码:CW6X5B10I8V6 HD6V7S1V6A10 ZI6L7G3F6H5文档编
