Keywords

Difference - The difference is the result after subtracting one number from another.
Sum - The sum is the total when numbers are added together.

Difference can only be found by subtracting the subtrahend from the minuend.
Subtract the subtrahend from the minuend when they are far apart. When close together, find the difference counting up from the subtrahend.
Teacher tip
Promote the use of trial and improvement with the pupils. This is an excellent mathematical strategy that encourages pupils to 'have a go', to try out numbers, make mistakes and learn from these.
