1、三年级数学上册期末总复习资料（必考知识点归纳）时 分 秒1、钟面上有3 根针，它们是（时针）、（分针）、（秒针），其中走得最快的是（秒针），走得最慢的是（时针）。2、钟面上有(12)个数字，(12)个大格，(60)个小格；每两个数间是(1)个大格，也就是(5)个小格。3、时针走 1 大格是(1)小时；分针走 1 大格是(5)分钟，走 1 小格是(1)分钟；秒针走 1 大格是(5)秒钟，走 1 小格是(1)秒钟。4、时针走 1 大格，分针正好走(1)圈，分针走 1 圈是(60)分，也就是(1)小时。时针走 1 圈，分针要走(12)圈。5、分针走 1 小格，秒针正好走(1)圈，秒针走 1 圈是(6
2、0)秒，也就是(1)分钟。6、时针从一个数走到下一个数是(1 小时)。分针从一个数走到下一个数是(5 分钟)。秒针从一个数走到下一个数是(5 秒钟)。7、钟面上时针和分针正好成直角的时间有：（3 点整）、（9 点整）。8、公式。（每两个相邻的时间单位之间的进率是60）1 时=60 分 1 分=60 秒半时=30分 60 分=1时60 秒=1分 30 分=半时万以内的加法和减法1、认识整千数（记忆：10 个一千是一万）2、读数和写数（读数时写汉字写数时写阿拉伯数字）精品资料-欢迎下载-欢迎下载 名师归纳-第 1 页，共 6 页 -一个数的末尾不管有一个0 或几个 0，这个 0 都不读。一个数的中
3、间有一个0 或连续的两个 0，都只读一个 0。3、数的大小比较：位数不同的数比较大小，位数多的数大。位数相同的数比较大小，先比较这两个数的最高位上的数，如果最高位上的数相同，就比较下一位，以此类推。4、求一个数的近似数：记忆：看最位的后面一位，如果是0-4 则用四舍法，如果是5-9 就用五入法。最大的三位数是位999，最小的三位数是 100，最大的四位数是 9999，最小的四位数是 1000。最大的三位数比最小的四位数小1。5、被减数是三位数的连续退位减法的运算步骤：列竖式时相同数位一定要对齐；减法时，哪一位上的数不够减，从前一位退1；如果前一位是0，则再从前一位退 1。6、在做题时，我们要注
4、意中间的0，因为是连续退位的，所以从百位退1到十位当 10 后，还要从十位退1 当 10，借给个位，那么十位只剩下9，而不是10。（两个三位数相加的和:可能是三位数，也有可能是四位数。）7、公式和加数另一个加数加数和另一个加数减数被减数差被减数减数差精品资料-欢迎下载-欢迎下载 名师归纳-第 2 页，共 6 页 -文档编码:CG1W10S10N7V4 HR7A6H1X9S4 ZT10O9R7S9S9文档编码:CG1W10S10N7V4 HR7A6H1X9S4 ZT10O9R7S9S9文档编码:CG1W10S10N7V4 HR7A6H1X9S4 ZT10O9R7S9S9文档编码:CG1W10S1
