## Lesson details

### Key learning points

1. There are 24 hours in a day
2. Times after midday keep counting on from 12
3. On the 24 hour clock the hours start at 0 and end at 23

### Common misconception

Part of the lesson requires pupils to decide whether times are before midday, at midday or after midday. Pupils can find categorising 12:00 and 00:00 tricky.

Explicit teaching points are made based around this in the slide deck. However, it is worth really focusing on these points as they come up and, when assessing the pupils during the Practice tasks, paying particular attention to those times.

### Keywords
