2. Build Understanding

How the hour hand moves after every 15 minutes
1 hour is 60 minutes, so when the minute hand rotates one full circle, the hour hand moves to the next
number.
When the minute hand moves 15 minutes, which is a quarter of 60 minutes, the hour hand also moves a
quarter of the way to the next number.
