  1. 找规律 鲁迅小学 王玉珏

  2. 一、直接说出得数。 9×6 = 8×11 = 12×3 = 5×13 = 54 88 36 65

  3. 一、直接说出得数。 24×2 = 17×3 = 40×4 = 5×61 = 48 51 160 305

  4. 说出下面算式中各部分名称。 40 × 4 = 160 ……积 ……乘数 ……乘数

  5. = 6 = 5 = 50 = 60 = 500 = 600 = 48 你发现了什么? = 480 = 4800

  6. 试练： 150×30 = 150×40 = 4500 6000 为什么150×40=6000的乘数一共有2个0，可乘积6000中却有3个0？是不是算错了？

  7. 24 240 480 720

  8. = 1600 = 1200 = 2400 = 1000

  9. = 720 = 260 = 750 = 560

  10. 根据每组中的第一个算式填空。 12×3 = 36 （ ）×30 = 360 （ ）×30 = 3600 12 120

  11. 5×13 = 65 5 × （ ） = 650 5 0× （ ） = 6500 130 130

  12. 15×2 = 30 （ ）×20 = 300 150×（ ）= 3000 15 20

  13. 40 ×（ ）< 65 30× （ ） < 165 5 0× （ ） < 210 1 5 4

  14. 80 ×（ ）< 550 20× （ ） < 87 7 0× （ ） < 200 6 4 2
