Count the minute spaces

It is 25 minutes past three in the afternoon. What do the two hands tell us?

  1. Start at three o’clock. The short hand shows the hour; the long hand begins at twelve.

    3:00: the hour is three.
  2. Each big number marks five minutes. Count five, ten, fifteen, twenty, twenty-five to reach the 5.

    5 × 5 = 25 minutes

    The minute hand at 5 means 25 minutes.
  3. The short hand is part of the way from three to four. Read the time as 3:25. Because our story says afternoon, use pm.

  1. Find the short hand for the hour and the long hand for minutes.

    The short hand locates the hour and the long hand counts minutes past it. The story tells us whether to use am or pm.

    123456789101112
    Short hand: hour. Long hand: minutes.
  2. Read the hour from the short hand.

    123456789101112
    Short hand: hour. Long hand: minutes.
    Read the clock. It is after noon.

  3. Read minute marks from the long hand.

    123456789101112
    Short hand: hour. Long hand: minutes.
  4. Use the time-of-day information: 10:50 pm.

    123456789101112
    Short hand: hour. Long hand: minutes.
  5. Check the result against the question we started with.

    The hour hand moves between hour numbers as the minutes pass.

    We found 10:50 pm. The short hand locates the hour and the long hand counts minutes past it. The story tells us whether to use am or pm.

    123456789101112
