五年级上册数学小数乘除法口算练习题 (含答案)
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，1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。

人教版五年级上册数学口算,速算,巧算题
人教版五年级上册数学口算, 速算, 巧算题一、引言在学习数学的过程中，口算是一个非常重要的环节。
通过口算练习，可以提高学生的计算能力和反应速度，培养学生对数字的敏感度和逻辑思维能力。
在人教版五年级上册数学教材中，有许多有趣的口算、速算和巧算题，下面我们来逐一共享一些精彩的例子。
二、口算题1. 计算：486 + 237 - 198 = ？步骤：先进行加法运算，然后再减法运算。
答案：486 + 237 = 723，723 - 198 = 525。
2. 已知378 ÷ 6 = ？计算步骤：将378除以6。
答案：378 ÷ 6 = 63。
三、速算题1. 23 × 7 = ？计算步骤：先将23分解为20和3，然后依次与7相乘。
答案：23 × 7 = (20 × 7) + (3 × 7) = 140 + 21 = 161。
2. 45 × 8 = ？计算步骤：先将45分解为40和5，然后依次与8相乘。
答案：45 × 8 = (40 × 8) + (5 × 8) = 320 + 40 = 360。
四、巧算题1. 计算：39 × 11 = ？巧算步骤：先将39分解为30和9，然后依次与11相乘。
巧算答案：39 × 11 = (30 × 11) + (9 × 11) = 330 + 99 = 429。
2. 计算：67 × 8 = ？巧算步骤：将67分解为60和7，然后依次与8相乘。
巧算答案：67 × 8 = (60 × 8) + (7 × 8) = 480 + 56 = 536。
五、结语在数学学习中，口算、速算和巧算都是非常重要的。
通过不断的练习和积累，学生可以提高自己的计算能力，从而更好地应对数学学习中的各种挑战。
希望以上的口算、速算和巧算题例子能够帮助学生更好地理解和掌握这些知识，为他们的数学学习之路增添一份乐趣和成就感。
