Lesson details
Key learning points
- Adding two to an odd number gives the odd number after.
- Subtracting two from an odd number gives the odd number before.
- When we count forwards in odd numbers, we add two more each time.
- When we count backwards in odd numbers, we subtract two each time. The result is two less.
Keywords

Common misconception
Children may incorrectly identify the odd number 'before' or 'after' the one given.
Provide practice in the form of missing number problems where children must identify the odd numbers before or after one given. Do this until fluent. Initially, allow children to use a number line. Remove this scaffold once feeling more confident.
