Key learning points
Consecutive even numbers have a difference of 2
We can use our knowledge to solve missing number problems when 2 is the known part.
Common misconception
Children may resort to counting strategies without noticing that the relationship between the minuend and the subtrahend is that there is a difference of two.
Draw out the patterns that will allow children to solve these equations without needing to using counting strategies. For example, 4 + 2 and 2 + 4 are 'even number after'; 6 - 2 is 'even number before' and 6 - 4 is 'difference of two'.
