1、1 小学五年级数学上册复习教学知识点归纳总结第一单元小数乘法1、小数乘整数：意义求几个相同加数的和的简便运算。如：1.5 3 表示求 3 个 1.5 的和的简便运算（或1.5 的 3 倍是多少）。计算方法：先把小数扩大成整数；按整数乘法的法则算出积；再看因数中一共有几位小数，就从积的右边起数出几位点上小数点。2、小数乘小数：意义就是求这个数的几分之几是多少。如：1.5 0.8 就是求 1.5 的十分之八是多少（或求1.5 的 1.8 倍是多少）。计算方法：先把小数扩大成整数；按整数乘法的法则算出积；再看因数中一共有几位小数，就从积的右边起数出几位点上小数点。注意：按整数算出积后，小数末尾的0

2、要去掉，也就是把小数化简；位数不够时，要用 0 占位。3、规律：一个数（0 除外）乘大于1 的数，积比原来的数大；一个数（0 除外）乘小于1 的数，积比原来的数小。2 4、求近似数的方法一般有三种：四舍五入法；进一法；去尾法5、计算钱数，保留两位小数，表示计算到分；保留一位小数，表示计算到角。6、小数四则运算顺序和运算定律跟整数是一样的。7、运算定律和性质：加法：加法交换律：a+b=b+a 加法结合律:(a+b)+c=a+(b+c)减法：a-b-c=a-(b+c)a-(b+c)=a-b-c 乘法：乘法交换律：ab=ba 乘法结合律：(a b)c=a(b c)乘法分配律：(a+b)c=ac+bc

10、至右分别为列数和行数，即“先列后行”。2、作用：一组数对确定唯一一个点的位置。经度和纬度就是这个原理。例：在方格图（平面直角坐标系）中用数对（3，5）表示（第三列，第五行）。注：（1）在平面直角坐标系中X轴上的坐标表示列，y 轴上的坐标表示行。如：数对（3,2）表示第三列，第二行。（2）数对（X，5）的行号不变，表示一条横线，（5，Y）的列号不变，表示一条竖线。（有一个数不确定，不能确定一个点）2、图形左右平移行数不变；图形上下平移列数不变。第三单元小数除法1、小数除法的意义：已知两个因数的积与其中的一个因数，求另一个因数的运算。文档编码:CC2W7D10Z8Y4 HM4P5N3U4O2 ZI

18、有余数，要添 0 再除。3、除数是小数的除法的计算方法：先将除数和被除数扩大相同的倍数，使除数变成整数，再按“除数是整数的小数除法”的法则进行计算。注意：如果被除数的位数不够，在被除数的末尾用0 补足。4、在实际应用中，小数除法所得的商也可以根据需要用“四舍五入”法保留一定的小数位数，求出商的近似数。5、除法中的变化规律：商不变：被除数和除数同时扩大或缩小相同的倍数（0 除外），商不变。除数不变，被除数扩大，商随着扩大。被除数不变，除数缩小，商扩大。6、循环小数：一个数的小数部分，从某一位起，一个数字或者几个数字依次不断重复出现，这样的小数叫做循环小数。循环节：一个循环小数的小数部分，依次不断

19、重复出现的数字。如6.3232 的循环节是32.文档编码:CC2W7D10Z8Y4 HM4P5N3U4O2 ZI9A7H5O10C4文档编码:CC2W7D10Z8Y4 HM4P5N3U4O2 ZI9A7H5O10C4文档编码:CC2W7D10Z8Y4 HM4P5N3U4O2 ZI9A7H5O10C4文档编码:CC2W7D10Z8Y4 HM4P5N3U4O2 ZI9A7H5O10C4文档编码:CC2W7D10Z8Y4 HM4P5N3U4O2 ZI9A7H5O10C4文档编码:CC2W7D10Z8Y4 HM4P5N3U4O2 ZI9A7H5O10C4文档编码:CC2W7D10Z8Y4 HM4P5N
