一、填一填。
9 +( )=10 7 +( )=10 5+( )=10
8 +( )=10 6 +( )=10 ( )+ 1 =10
( )+ 3 =10 ( )+ 2 =10 ( )+4 =10
(
8 + 7 =
10
) (
8 + 4 =
10
) (
8 + 3 =
10
)二、填一填。
(
8 + 6 =
10
) (
8 + 5 =
10
) (
8 + 8 =
10
)
(
7 + 4 =
10
) (
8 + 9 =
10
) (
8 + 9 =
10
)
(
7 + 5 =
10
) (
7 + 7 =
10
) (
7 + 6 =
10
)
(
7 + 9 =
10
) (
7 + 8 =
10
) (
7 + 8 =
10
)
(
6 + 5 =
10
) (
6 + 6 =
10
) (
7 + 9 =
10
)
(
6 + 8 =
10
) (
6 + 7 =
10
) (
6 + 7 =
10
)
(
6 + 9 =
10
) (
6 + 9 =
10
) (
6 + 8 =
10
)
(
5 + 6 =
10
) (
5 + 6 =
10
)
三、先比一比,在算一算。
9+1+2= 9+1+6= 9+1+8= 9+1+1=
9+3= 9+7= 9+9= 9+2=
9+1+3= 9+1+7= 9+1+4= 9+1+5=
9+4= 9+8= 9+5= 9+6=
8+2+1= 8+2+5= 8+2+7= 8+2+2=
8+3= 8+7= 8+9= 8+4=
8+2+3= 8+2+6= 8+2+4= 8+2+7=
8+5= 8+8= 8+6= 8+9=
7+3+3= 7+3+1= 7+3+4= 7+3+5=
7+6= 7+4= 7+7= 7+8=
7+3+2= 7+3+6= 6+4+4= 6+4+2=
7+5= 7+9= 6+8= 6+6=
6+4+1= 6+4+5= 6+4+7= 6+4+9=
6+5= 6+9= 6+11= 6+13=
