# Explain the difference between consecutive odd numbers

I can explain the difference between consecutive odd numbers.

## Lesson details

### Key learning points

- Consecutive odd numbers have a difference of 2
- We can use this 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, 5 + 2 and 2 + 5 are 'odd number after'; 7 - 2 is 'odd number before' and 7 - 5 is 'difference of two'.

### Keywords
