Worked examples

Model ItI do

The short hand points to 3 and the long hand points to 12. What time is it?

When the long hand points to 12, it is an o'clock time. The short hand is on the 3, so the time is 3 o'clock, or 3:00.

Try It TogetherWe do

The long hand points to 6 and the short hand is just past 4. What time is it?

When the long hand points to 6, it is half past the hour. The short hand is past 4, so the time is half past 4, or 4:30.
