Number Bonds

WALT:We are learning to use the making ten/Tidy numbers strategy

To 10
9+1=10
8+2=10

To 20 
12+8=20
11+9=20

To 50 
41+9=50
44+6=50

To 100
96+4=100
95+5=100
                                 
8+7=15                    
8+2=10 if I add    
5 more its 15

9+6=15
9+1=10
10+5=15


It was easy because I know what number bonds are.


Do you know what any other number bonds are?
