的数比较大小，位数多的数大于位数少的数。例如：1000 999 四位数 三位数 两位数 一位数 位数相同 的数比较大小，先比较最高位，最高位上数字大的那个数大，如果最高位上的数字相同，依次比较下一位上的数。例如：123 223 652 654 7.在数线上标出数的大致位置：先找出数线上标出的数的规律，再根据所给数的大小标出数的大致位置。文档编码:CS3A5S4F9I6 HW2J3H3X10U2

就是几厘米。方法二：测量物体时，也可以从一个整刻度到另一个整刻度，大刻度减去小刻度的差，就是物体的长度。7.如何画一条几厘米的线？画线时，要先确定一个端点，将线的端点对准所选刻度，再沿着直尺往右画，画到规定的长度，再标上另一个端点，最后标明线的长度。文档编码:CS3A5S4F9I6 HW2J3H3X10U2 ZN3I6U7T8L6文档编码:CS3A5S4F9I6 HW2J3H3X10U2
