【导语】学好数学,在你熟知理论的前提下,需要通过做各种类型题,确保自己将理论熟练运用。每个成功,除了有“三分”天注定,更有“七分”靠打拼,现在的勤奋,就是为了将来的成功!为各位勤奋的学子准备了下列试题,供大家练习。
一、计算。(24分)
1.直接写出得数。( 16分)
5×6= 24÷4= 40+30= 30÷5=
18÷3= 4×2= 15÷5= 36-6=
20-4= 18+9= 6×4= 9÷3=
5×2+9= 3×4-5= 5×5+3= 6×5-6=
2.竖式计算。(8分)
85-29-38= 64+8+17=
45+38-24= 62-39+25=
二、填空。(33分)
1.两个乘数都是5,积是( );被除数是16,除数是4,商是( )。
2.2个6相加的和是( ),2和5相加的和是( )。
3.由4条边围成的图形是( )边形,六边形是由( )条边围成的。
4.在○里填上“>”、“<”或“=”。
16÷4○3×4 20+5○20÷5 47-38○3×3
29+4○6×6 12÷4○6÷2 6×1○6÷3
5.写出2道除数是5的除法算式。
6.4×□<16,□里填( );3×□>15,□里最小填( )。
7.第一行7根小棒,第二行13根小棒,第一行添上( )根小棒就和第二行同样多;从第二行拿( )根摆到第一行,两行小棒同样多。
8.20个苹果,最少拿掉( )个正好可以平均分给6个小朋友。
三、操作。( 8分)
1.在下面的钉子板上画一个平行四边形和一个六边形。(4分)
