一．两位数的加减法 1. 两个数相加减

43-25= 73+14= 36-27= 22+18= 40-17= 52+16= 62-59= 52-34= 82-33= 61-39= 78-29= 37+18= 47+19= 46-19= 76-18= 36+27= 46-38= 65-26= 25+8= 55+17= 45-16= 42-19= 74-18= 44-17= 38-16= 34+58= 53-29= 63+28= 36+17= 53+16= 32-17= 91-17= 36+16= 91-25= 40+13= 67-28= 84+9= 29+35= 45+9= 72-17= 58-29= 47+18= 47+29= 76-19= 76-38= 46+27= 56-38= 75-26= 45+8= 75+17= 35-16= 42-29= 74-68= -17= 48-36=

2. 三个数相加减

14+16+30= 28+56+1= 95+1+3= 65+25+7= 80+16+3= 34+11+52= 6+21+51= 70+4+17=

65+26+3=

1+86+4= 78+19+2= 87+7+1= 47+28+18= 68+23+8= +21+5= 47-25-3= 63-44-6= 44-19-18=

3. 带括号的三个数相加减

-(51-24)= 32-(24+3)= 82-(53+10)= 85-(44+8)= 98-(23-17)= (-37)-16= 82-(9+3)= 98-(97-1)= 96-(84-2)=二.99乘法表

1. 完整99乘法表的填写

1x1= 1x2= 2x2= 1x3= 2x3= 3x3= 1x4= 2x4= 3x4= 4x4= 1x5= 2x5= 3x5= 4x5= 5x5= 1x6= 2x6= 3x6= 4x6= 5x6= 6x6= 1x7= 2x7= 3x7= 4x7= 5x7= 6x7= 7x7= 1x8= 2x8= 3x8= 4x8= 5x8= 6x8= 7x8= 8x8=

1x9= 2x9= 3x9= 4x9= 5x9= 6x9= 7x9= 8x9= 9x9=

2. 随机99乘法表的填写

1x5= 1x8= 2x6= 2x9= 3x7=

3x9= 4x8= 4x6= 2x4= 1x7= 6x8= 7x8= 6x7= 8x9= 7x9= 4x9= 3x8= 6x9= 6x9= 7x7=
