整十数加、减整十数练习题
整十数加减整十数
想一想：
30－20你是怎样计算的？
30 － 20 =
3个十 减 2个十
10
是（ 1 ）个十， 就是（ 10 ）
30 － 10 =
20 计算整十数减整十数，只需把相 减的两个数的十位上的数字进行 相减，然后在末尾加上0。
40＋20＝60 60－20＝40 60－ 40＝20
看图只白羊，20只黑羊，白羊比黑羊多几只？
60 － 20 = 40（只）
（90）○（20）=（ 70 ）
1、小红买了30支铅笔，小兰买了10支铅笔，她们一共买了多少支铅笔？
30 + 10 = 40（支）
2、一个书包30元，小明给了50元，应找回多少元？
50 － 30 = 20（元）
3、大课间，一（2）班有40根跳绳，男同学拿走了20根，还剩多少根？
40 － 20 = 20（根）

1、猜猜我是谁
我比10多20
30
30里面有（3 ）个十
我比50多30
80
80里面有（ 8）个十
我比60少20
40
40里面有（4 ）个十
10
1个十
+ 20 = 30
加 2个十 是（ 3 ）个十， 就是（ 30 ）
谁会计算：20 + 10 = 30 10 + 20 = 30 计算整十数加整十数，只需把相 加的两个数的十位上的数字进行 相加，然后在末尾加上0。 我会算： 50+20 = 7 0 30+20 = 5 0
