小学一年级下册数学计算题50道一.计算题(共50题,共473分)1.看图列式。
2.通过计算找到邻数。
(1)23+1=________ 23-1=________(2)80+1=________ 80-1=________3.先圈一圈,再计算。
圈一圈:_____12-8=_____想:8加_____等于12,所以12-8=_____;也可以先计算10-8=_____,再计算_____+_____=_____。
4.在数射线上做加减法。
(1)3+4=________(2)33+4=________5.17-7+9= 13+5-11= 15-14+15= 4+6-10=2+4+14= 16-7-9= 8-3+2= 16-3+6=6.比一比,看谁算得快!2+3= 5+5= 6+3= 11+3= 13+4=7+2= 12-2= 17-6= 18-4= 19-0=7.看谁2分钟都能算对。
11-6=________ 18-7=________ 12-8=________16-9=________ 12-7=________15-8=________ 11-8=________ 17-8=________12-9=________ 13-8=________16-8=________ 13-7=________ 11-9=________14-8=________ 16-7=________14-7=________ 15-7=________ 14-6=________18-9=________ 11-7=________8.想一想,算一算。
42+4=________ 34+5=________6+53=________ 4+3=________14+3=_______ 34+3=________15+3=________ 25+3=________17+2=________ 27+2=________9.算一算。
