## Lesson details

### Key learning points

- One more and one less can be used to order numbers 0 to 10
- A number line shows the position of numbers 0 to 10
- On a 0 to 10 number line, 5 is in the middle. It is the midpoint.
- Knowledge of relative size of 6, 7, 8, 9 can be used to position these numbers on the number line.

### Common misconception

Pupils do not understand that intervals or marks on a number line need to be equally spaced and that in these cases each mark represents one number.

Make connections between number tracks and number lines showing that the intervals are counted on a number line. Expose pupils to vertical and horizontal number lines showing all numbers, including beyond 10, to familiarise them with their structure.

### Keywords
