Bonds
What is a number bond?
• a mental picture of the relationship
between a number and the parts that
combine to make it.
• sometimes called an addition fact, it is a
simple addition sum which has become
so familiar that a child can recognise it
and complete it almost instantly

Another example
25 + 45 =
Step 1: Add the ones
5 + 5 = 10
Step 2: Regroup 10
ones into 1 ten and 0

Addition and Subtraction
An example of Subtraction
46 - 29 =
Step 1: Regroup 4 tens 6
ones into 3 tens 16 ones
Step 2: 16 – 9 = 7
Step 3: Subtract the
tens
