十几减 9 练习题
姓名：
班级：
1、 先填出计算的思维过程，再填出得数。
11-9=
想：9 加(
)得 11,所以 11 减 9 得( )。
14-9=
想：9 加(
)得 14,所以 14 减 9 得( )。
17-9=
想：9 加(
)得 17,所以 17 减 9 得( )。
2、 你会这样算么？请试着在每一个圆圈中填上合适的数字。
15 – 9 = 15– 5 - 4
= 6 17 – 9 = 17– - = 14 – 9 = 14– - = 18 – 9 = 18– - = 13 – 9 = 13–
-
=
3、 以此从下面的数中减去九写出得数，并说一说你发现了什么？

《十几减9》练习题（附答案）
1.口算。
15-9= 11-9= 18-9=
12-9= 17-9= 13-9=
14-9= 16-9= 19-9=
导学点睛：10比9多1,用“破十法”计算十几减9,可以用“几加1”直接求出结果。
2.算一算。
11-9+3= 12-9-3= 8+9-9=
14-9+7= 13-9+8= 17-9-4=
5+7-9= 6+8-9= 16-9+2=
7+7-9= 9+2-9= 14-2-9=
15-9+3= 5+8-9= 8+7-9=
导学点睛：一个算式里有加法和减法要按照从左到右的顺序进行计算。
3.蜜蜂采蜜。
导学点睛：先算出各算式的得数,再把算式和得数连起来。
你发现差是怎样随着被减数的变化而变化的呢?
4.在○里填上“>”“<”或“=”。
11-9○4 12-9○3 15-9○7
14-9○5 13-9○3 17-9○6
