名师精编优秀教案第 七册 第一单元认识更大的数教学计划天河区柯木塱小学数学科四年级备课组一、学生学习情况分析四年级（1）班 42 人（2）班 45 人，两个班课堂纪律都比较好，但总感觉课堂气氛不够活跃，爱提问题、爱表达的同学比较少。经摸查，四（1）班学生有 92%能对 100 以内及万以内数进行正确的读写。四（2）班学生有 87%能对 100以内及万以内数进行正确的读写。二、单元教学目标1、经历收集日常生活中常见的大数的过程，感受学习更大数的必要性，体会大数的实际意义。2、通过操作活动认识数的计数单位，了解各单位之间的关系，并会正确读、写以及比较数的大小。3、在描述数据的过程中，认识数据改写单位的必要性，能用万、亿为单位表示大数。4、理解近似数在实际生活中的作用，能够根据实际问题的需要求一个数的近似数。三、单元学习内容的前后联系1、已学过的相关内容：一年级100以内数的认、读、写及二年级万以内数的认、读、写。2、后续学习的相关内容：四年级下册的求积、商的近似值。四、教学重点、难点名师精编优秀教案重点：1、感受学习大数的必要性、体会较大数的实际意义。2、会正确读、写亿以内的数。3、把较大的整万、整亿数改写成以万、亿为单位的数。4、用“四舍五入”法求一个数的近似数。难点：1、相邻计数单位之间的关系。2、能正确读、写每级中间或末尾有零的多位数。3、多个大数按大小顺序进行排列。4、能根据不同需要求近似数。五、单元评价要点本单元知识技能主要是亿以内数的计数单位的改写、读写，大数的比较与单位的改写以及用“四舍五入”法求近似数。六、各小节教学目标及课时安排本单元计划课时数：11 节教学内容教学目标计划课时授课日期备注数一数：体会较大数的实际意义通过数正方体等操作活动,在具体情景中认识较大的数；体会较大数的实际意义。1 09-05 认一认认识“十万”“百万”“千万”“亿”等较大的计数单位，了解相邻单位之间的关系。1 09-06 文档编码:CW7K3Y5O7C2 HQ8N8Y3N7C2 ZH10S2Y4L8T7文档编码:CW7K3Y5O7C2 HQ8N8Y3N7C2
