1、计算填空:
( )-1=8 8 -( )= 6 ( )-2=6 7 -( )= 3 ( )-8=6 10 -( )= 7 ( )-2=7 14 -( )= 2 ( )-3=9 6 -( )= 1
( )+3=9 ( )+6=9 ( )+6=10 ( )+6=8 ( )+4=7
2+( )= 6 7+( )= 10 2+( )= 7 5+( )= 9 4+( )= 7
2、数的分解与组合填空、列算式:
10 4
10 8
4+( )= 10
3 5 3+5=( )
( )+ 8=10 3、给下列数字排序:
① 9
)<( )>(
3 5 2 10 7 6 4
( (
)<( )<( )<( )<( )<( )<( ) )>(
)>( )>( )>( )>( )>( )
② 6 1 5
8
)<( )>(
4 2 7 10 ( (
)<( )<( )>( )>(
)<( )<( )<( )<( ) )>( )>( )>( )>( )
4. 列式计算
(
)+( )=( )( )-( )=( )
