Step 1: Let's Learn

Read it, or press Listen and follow the words.

You cut circles into halves. A clock face is a circle too.

Half way round

When the long hand has gone half way round, we say half past.

Watch the short hand

At half past 3, the short hand sits between the 3 and the 4.

It is still half past 3, because 3 already started. Write it as 3:30.

Why half past is halfway

The long hand has gone half the way round the face. That is the same halving you did with shapes, applied to a circle.

The short hand moves too

At half past three the hour hand sits between three and four, not on the three. It has been creeping the whole time.

Step 2: Try It Yourself

Move the minutes to 30 and watch the short hand slide.

Set the minutes to 30. Watch the short hand move too.
