19—20学年五年级第一学期期末专项复习一(第2单元知识梳理及单元测试卷)
第二单元知识梳理1．平行四边形的面积计算(1)沿着平行四边形的任意一条高剪开，通过平移拼成(转化成)一个长方形。
长方形的长等于平行边形的底，长方形的宽等平行四边形的高。
长方形的面积拼成的平行四形的面积相等(等面积变形)，因为长方形的面积＝长×宽，所以平行四边形的面积＝底×高，用字母表示为S＝a×h。
注意点：每个平行四边形的底和高都有两组，计算面积时要用相对应的一组底和高相乘。
(2)把长方形框架拉成平行四边形，周长不变，但高变小了，所以面积也变小了；同理，把平行四边形框架拉成长方形，周长不变，高变大了，所以面积也变大了。
2．三角形的面积计算将两个完全一样的三角形拼成一个平行四边形，这个平行四边形的底等于三角形的底，平行四边形的高等于三角形的高，拼成的平行四边形的面积是每个三角形面积的2倍，每个三角形的面积是拼成的平行四边形面积的一半。
因为平行四边形的面积＝底×高，所以三角形的面积＝底×高÷2，用字母表示为S＝ah÷2。
3．梯形的面积计算将两个完全一样的梯形拼成一个平行四边形，这个平行四边形的底等于梯形的上底与下底的和，平行四边形的高等于梯形的高，拼成的平行四边形的面积是每个梯形面积的2倍，每个梯形的面积是拼成的平行四边形面积的一半。
因为平行四边形的面积＝底×高，所以梯形的面积＝(上底＋下底)×高÷2，用字母表示为S＝(a＋b)h÷2。
4．组合图形的面积计算(1)将组合图形分割成若干个简单图形，然后求各个图形的面积之和。
(2)将组合图形添补成学过的简单图形，然后用大图形的面积减去添补图形的面积。
5．用数方格的方法估计图形的面积至少：只数整格;至多：把不满整格的当作整格数；大约：先数整格的，再数不满整格的，把不满整格的按半格计算。
注：如果只数整格，实际面积会比数出的结果大一些;如果把不满整格的也当作整格数，实际面积会比数出的结果小一些只有先数整格的，再数不满整格的，把不满整格的按半格计算，数出的结果才比较合理。

19-20第一、二单元测试评讲课
第7-8 课时（10月8-9日）№：019-020教学内容：第一二单元测试评讲课教材简析：本试卷共包括五大项，第一项是直接写得数，第二项是填空，第三项是判断，第四项是用竖式计算，第五项是解决问题。
以上五项涵盖了第一二单元除法和认数的所有内容。
教学目标：通过检测和评讲，了解学生对第一二单元知识的理解和掌握情况，以及时进行查漏补缺。
重点难点：评讲典型错题。
教学准备：试卷、小黑板。
教学过程：一、宣布测试成绩2.表扬成绩进步比较大的同学周沫张涛陈姿旭黃继陈彦彦陆巍巍王启二、学生自查自析1.找出错题，分析错因。
2.订正错题。
3.小组交流：说出错误原因及改正方法。
三、重点讲评（二）填空。
1.很久以前，还没有计数符号的时候，我们的祖先常用的计数方法有（）、（）和刻痕计数。
分析：这道题出错最多，大部分的同学都没填，问其原因，都说上课时老师没讲。
这其实是课本第22页“你知道吗”的内容。
从反馈的情况看，学生阅读课本的习惯还不够，我们的教与学的方式还有待于改进。
÷2里可以填（）；要使商是一位数，里要填（）。
分析：被除数十位上的数字必须等于或大于2，所以里可以填的数字是2至9中的任意一个；而要使商是一位数，被除数十位上的数字必须小于2，所以只能填1。
好多同学由于没有认真分析，故出错较多。
(五)解决问题3.张叔叔要组装120辆玩具小汽车，工作3天后，还差27辆没装。
这3天张叔叔平均每天装多少辆？分析：正确的解法是：120-27=93（辆）93÷3=31（辆）有部分同学直接用120÷3=40（辆）了，还有部分同学式子列对了，但算错了。
分析数量间的关系，解决问题的能力还有待于练习和提高。
4.5个教师带62名学生坐船过河，每条船最多坐6人，至少要多少只船才能一次性把他们运走？分析：正确的解法是：5+62=67（人） 67÷6=11（只）……1（人）答：至少要12只船才能一次性把他们运走。

19除以20的竖式计算方法
19除以20的竖式计算方法
你看哈，咱先写好竖式的格式。
把19写在除号里面，20写在除号外面。
这就像是19个小宝贝要被20个小组来分呢。
然后呢，因为19比20小呀，不够除呢，这时候咱就在19的上面商0，这个0就像是一个小占位符，告诉大家这里暂时还没有分到东西呢。
接着呢，我们就在19后面添个0，变成190啦，就好像给这19个小宝贝找来了一些帮手，让它们能被分一分。
那20乘以9等于180呢，这个9就是我们试出来的商啦。
把180写在190的下面，然后做减法，190 - 180等于10呢。
这时候，我们发现还剩下10个小宝贝没被分完呢。
如果我们还想继续分的话，就又可以在10后面添个0，变成100，再继续除。
不过如果题目只要求到一定的精度，比如保留到小数点后一位或者两位，那咱们就可以停啦。
要是保留到小数点后一位呢，我们就看100除以20，20乘以5等于100，那商就是0.95啦。
这就像是把那些小宝贝分到得出了每个人能得到多少的结果呢。
宝子，竖式计算就是这么个有趣的过程，就像玩一个分东西的小游戏一样。
你要是多做几次这样的计算，就会越来越熟练啦。
