四年级下册混合运算(人教版)
人教版小学四年级下册数学 6.1《小数加减混合运算》 -含答案
加油！有志者事竟成答卷时应注意事项１、拿到试卷，要认真仔细的先填好自己的考生信息。
２、拿到试卷不要提笔就写，先大致的浏览一遍，有多少大题，每个大题里有几个小题，有什么题型，哪些容易，哪些难，做到心里有底；３、审题，每个题目都要多读几遍，不仅要读大题，还要读小题，不放过每一个字，遇到暂时弄不懂题意的题目，手指点读，多读几遍题目，就能理解题意了；容易混乱的地方也应该多读几遍，比如从小到大，从左到右这样的题；４、每个题目做完了以后，把自己的手从试卷上完全移开，好好的看看有没有被自己的手臂挡住而遗漏的题；试卷第１页和第２页上下衔接的地方一定要注意，仔细看看有没有遗漏的小题；５、中途遇到真的解决不了的难题，注意安排好时间，先把后面会做的做完，再来重新读题，结合平时课堂上所学的知识，解答难题；一定要镇定，不能因此慌了手脚，影响下面的答题；６、卷面要清洁，字迹要清工整，非常重要；７、做完的试卷要检查，这样可以发现刚才可能留下的错误或是可以检查是否有漏题，检查的时候，用手指点读题目，不要管自己的答案，重新分析题意，所有计算题重新计算，判断题重新判断，填空题重新填空，之后把检查的结果与先前做的结果进行对比分析。
亲爱的小朋友，你们好! 经过两个月的学习，你们一定有不小的收获吧，用你的自信和智慧，认真答题，相信你一定会闯关成功。
相信你是最棒的！1小数的加法和减法（第1课时）小数加减混合运算一、口算 2.6＋l.4＝ 1.9＋ 0.8l＝ 0.58＋0.42＝ 1.63—1.23＝ 0.9－0.25＝ 9.9—0.01＝ 4—2.3＝ 3.2一1.7＝ 7.05－0.05＝ 0.78—0.38＝ 3.5十5.5＝ 5.5—3.9＝ 二、用竖式计算并验算 8.42＋9.48＝ 42.56＋3.124＝ 91.26－30.35＝ 验算：验算：验算： 15.6十0.237＝ 80－52.l＝ 7.35—1.41＝ 验算：验算：验算： 三、用小数计算 2吨50千克十630千克 5米80厘米十4米15厘米 5元6角十8元3角 四、选择题 1.用“米”作单位计算，“ 8米6厘米十5米60厘米”的正确算式是（）。

人教版四年级下册数学四则运算教案5篇
人教版四年级下册数学四则运算教案5篇四则混合运算应该是用来记录情境问题的步骤或解题计划的，是情境问题的另一种表述，四则混合运算式题是数字化的情境问题，所以从情境图入手是再合适不过了。
这里给大家分享一些关于人教版四年级下册数学四则运算教案，方便大家学习。
人教版四年级下册数学四则运算教案篇1教学内容：人教版四年级数学下册2——5页一、教学目标：1、熟练掌握一、二级运算单列式从左到右的运算顺序。
2、培养学生列综合算式解决实际问题的能力。
3、感受教学与生活的紧密联系。
二、教学重点、难点：1、同级运算的运算顺序。
2、发现并总结概括出没有括号的混合运算顺序。
三、教具、学具准备：主题图练习本四、教学过程(一) 创设情境，导入新课冬天你最喜欢什么运动?(堆雪人、打雪仗、滑冰、滑雪)这节课我们就来了解认识有关滑冰场情况。
(出示“冰雪天地”主题图)让学生认真观察图。
根据主题图和提示提出问题。
1、肯定学生的积极表现，引导学生回顾和本节内容相关的旧知识。
2、出示信息，多媒体展示问题。
(二) 结合情境，探究新知。
(1)天山滑雪场上午有72人，中午有44人离去，又有85人到来，现在有多少人在滑雪?A：师：根据信息你能提出什么数学问题?生：下午有多少人?生：滑雪场一共有多少人?师：你能有什么解决办法?师：引导学生交流，鼓励学生发表自己的看法。
B：给学生一定的思考时间，鼓励学生独立列算式，然后求解，师生共同总结。
C：表扬表现积极的学生，多媒体展示问题二：“冰天雪地”3天接待987人，照这样计算，6天预计接待多少人?D：请学生先进行独立思考，然后相互讨论。
E：强调算式的多样化，帮助学生理解。
例如：问题二中算式987÷3表示6天总共接待的人数，再乘以6表示6天总共接待的人数，他们的现实意义是相同的，所以两种算法都是正确的。
3、结运算规律，在没有括号的算式里，如果只有加减法或者只有除法，都要从左往右按顺序计算。
4、请学生做书中的小练习。

课本第9页 例4 （1）在96÷12 + 4×2的基础上加上小括号，变成96÷(12 + 4); 4)×2 = 96÷16 ×2
先算小括号内的加法 再算除法
= 6 ×2
最后算乘法
= 12
在进行递等式计算（即脱式计算）时， 没有算到的部分要原封不动地写出来。
课本第9页 做一做 先说一说下题的运算顺序，再计算。
360÷(70 - 4×16) 先算小括号内的乘法
= 360÷(70 - 64)
再算小括号内的减法
= 360÷6
最后算除法
= 60
（练习）学校书法兴趣小组男生有12人，女生有4人。美术兴趣 小组的人数是书法兴趣小组的2倍。美术兴趣小组有多 少人？ (12 + 4)×2 = 16×2 = 32（人）
答：美术兴趣小组有32人。
