A clock has two hands that work as a team:
Reading O'Clock
When the long hand points straight up to the 12, it is exactly the start of a new hour. Look at where the short hand points — that's the hour.
Example: short hand at 8, long hand at 12 → 8 o'clock
Reading Minutes — skip count by 5!
Reading any time — two steps:
1. Check the short hand — which number did it just pass? That's the hour.
2. Check the long hand — multiply the number it points to by 5. That's the minutes.
Example: short hand just past 4, long hand on 5 → 4:25
