1、精品教育-可编辑-人教版五年级数学下册复习资料第一单元观察物体三1、从不同角度观察一个物体，一次最多看到三个相邻的面。2、不可能一次看到长方体或正方体相对的面。第二单元因数和倍数1、在整数除法中,如果商是整数而没有余数,我们就说被除数是除数的倍数,除数是被除数的因数。（因数和倍数不包括0、小数、分数，只能在大于 0 的自然数中讨论。）2、一个数的因数的个数是有限的，最小的因数是1，最大的因数是它本身。3、一个数的倍数的个数是无限的，最小的倍数是它本身，没有最大的倍数。4、是 2 的倍数的数叫做偶数。不是2 的倍数的数叫做奇数。最小的奇数是 1，最小的偶数是 0。5、倍数的特征（1）2 的倍数的

2、特征：个位上是 0，2，4，6，8。（2）3 的倍数的特征：各位数字的和是 3 的倍数。（3）5 的倍数的特征：个位上是0 或 5。（4）2 和 5 的倍数的特征：个位上是0。（5）2 和 3 的倍数的特征：个位上是 0，2，4，6，8，且各位数字的和是 3 的倍数。精品教育-可编辑-（6）3 和 5 的倍数的特征：个位上是 0 或 5，且各位数字的和是3的倍数。（7）2、5 和 3 的倍数的特征：个位上是 0，且各位数字的和是3的倍数。6、同时是 2、3、5 的倍数，最小的两位数是30，最大的两位数是 90，最小的三位数是 120。7、只有 1 和它本身两个因数的数叫做质数（或素数）。质数只

3、有2 个因数。8、除了 1 和它本身两个因数外，还有别的因数的数叫做合数。合数至少有三个因数（即1、它本身、别的因数）。9、1 既不是质数，也不是合数。因为 1 只有 1 个因数。最小的质数是2，最小的合数是4。10、20以内的质数有：2、3、5、7、11、13、17、19 11、奇数奇数偶数奇数偶数奇数偶数偶数偶数奇数奇数奇数奇数偶数偶数偶数偶数偶数12、几个数公有的因数叫这些数的公因数。其中最大的那个因数就叫它们的最大公因数。13、几个数公有的倍数叫这些数的公倍数。其中最小的那个就叫它们的最小公倍数。14、如果两数成倍数关系，那么较小的数就是它们的最大公因数，较大的数就是它们的最小公倍数。

4、如果两数互质时，那么它们的最大公因数就是 1，它们的最小公倍数就是它们的积。文档编码:CS7S2H6P9L6 HF5S4B6S9P5 ZC1K8B8A4C3文档编码:CS7S2H6P9L6 HF5S4B6S9P5 ZC1K8B8A4C3文档编码:CS7S2H6P9L6 HF5S4B6S9P5 ZC1K8B8A4C3文档编码:CS7S2H6P9L6 HF5S4B6S9P5 ZC1K8B8A4C3文档编码:CS7S2H6P9L6 HF5S4B6S9P5 ZC1K8B8A4C3文档编码:CS7S2H6P9L6 HF5S4B6S9P5 ZC1K8B8A4C3文档编码:CS7S2H6P9L6 HF5S4

26、方体的长、宽、高同时扩大几倍，体积就会扩大倍数的立方倍。（如长、宽、高各扩大2 倍，体积就会扩大到原来的222 倍）。17、排水法：（计算不规则物体的体积），被浸没物体的体积等于上升那部分水的体积。计算方法：容器的底面积上升那部分水的高度。放入物体后的体积原来水的体积。18、把长方体或正方体截成若干个小长方体（或正方体）后，表面积增加了，体积不变。（截1 次，增加 2 个面）。第四单元分数的意义和性质1、单位“1”表示：一个物体、一个计量单位或是一些物体都可以看成一个整体。这个整体可以用自然数1 来表示，我们通常把它叫做单位“1”。2、把单位“1”平均分成若干份，表示这样的一份或几份的数，叫做

27、分数。3、把单位“1”平均分成若干份，表示这样的一份的数叫做分数单位。4、分数与除法的关系：除法中的被除数相当于分数的分子，除数相当于分母。分数后面不带单位表示两个量之间的倍数关系；分数带有单位表示一个具体的数量。5、分数大小的比较：文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D

34、化成同分母分数（先通分），再进行比较。6、分子比分母小的分数叫做真分数。真分数小于1。分子比分母大或分子和分母相等的分数叫做假分数。假分数大于或等于 1。7、把假分数化成整数或带分数：用分子分母。能整除的，所得的商就是整数；不能整除的，所得的商就是带分数的整数部分，余数是就是分数部分的分子，分母不变。8、分数的基本性质：分数的分子和分母同时乘以或除以相同的数(0除外)，分数的大不变。9、把一个分数化成和它相等，但分子、分母都比较小的分数，叫做约分。（约分成最简分数的方法是：分子和分母同时除以它们的最大公因数。）10、分子、分母是互质数的分数，叫做最简分数。最简分数的分子和分母的最大公因数是1。

35、11、把异分母分数化成和原来分数相等的同分母的分数，叫做通分。（通分的方法：先求出分母的最小公倍数，再根据分数的基本性质把各个分数化成用这个最小公倍数作公分母的分数。）12、小数化成分数：原来有几位小数，就在1 后面写几个 0 作分母，把原来的小数去掉小数点作分子；化成分数后，能约分的要约成最简分数。文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4

50、第七单元折线统计图1、折线统计图的特点：不但能看出数量的多少，而且还能看出数量的增减变化情况。条形统计图的特点：只能看出数量的多少。2、复式折线统计图画图时注意：一“点”（描点）、二“连”（连线）、三“标”（标数据）要用不同的线段分别连接两组数据中的数。第八单元数学广角找次品1、利用天平找次品的时候，把待分的物品分成3 份，能够平均分的平均分成 3 份。2、不能平均分的，也应使多的与少的一份只差1。这样不但能保证找出次品，而且称的次数一定最少。文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R2S1C3文档编码:CC4F8S2A5K7 HZ9Y2D8H9Z4 ZB6W9R
