Common core addition - Number bonds

Addition using number bonds uses the concept that “A whole thing is made up of parts”

Numbers can be split into 2 separate numbers that make one number

Numbers can be broken down in lots of different ways.

Example 1

6 plus 7 can be divided into number bonds then the common core addition can take place

NOTE:

Sometimes this is drawn with the circled numbers representing 10 complete.

Sometimes number bonds are can be circled to represent the sum of 10
