《3、快乐的小鸭》
1、看图写算式
(
=
) (
(
个)
) (
=
) (
(个)
)
(2)
2、画一画、填一填
14 – 7 =
11 – 6 =
3、我会这样算
15 – 6 = 12 – 7 =
17 – 8 = 16 – 7 =
4、口算
14 – 8 = 15 – 6 = 8 + 7 = 16 – 6 =
15 – 7 = 13 – 6 = 15 – 9 = 12 – 6 =
5、比一比,看谁算得又对又快
6 + 9 = 3 + 7 = 11 + 3 = 9 + 2 =
11 – 8 = 12 – 7 = 15 – 8 = 16 – 8 =
10 – 8 = 13 – 7 = 17 – 8 = 14 – 6 =
6、在( )填数,然后想一想,你发现了什么?
9 + ( ) = 15 6 + ( ) = 13 8 + ( ) = 14
15 – 9 = ( ) 13 – 6 = ( ) 14 – 8 = ( )
我发现了:
7、乐乐带15元钱去书店,买了一本《童话世界》,花了7元,乐乐还有多少钱?
8、在得数最大的算式下面的( )里画“√”
9、我会巧算
16 – 1 – 1 – 1 – 1 – 1 – 1 – 1
