Number Bonds  

 

 

 

Number bonds help students see that numbers can be "broken" into pieces to make computation easier.  With number bonds, students recognize the relationships between numbers through a written model that shows how the numbers are related.

A number bond is made up of parts that equal a whole. Here is an example:

 

 

           4 + 5 = 9     9 - 5 = 4

      5 + 4 = 9    9 - 4 = 5
