Telling time to the nearest minute: labeled clock | Math | 3rd grade | Khan Academy

  • 0:01 - 0:03
    - [Voiceover] Let's look
    at this clock and see
  • 0:03 - 0:06
    if we can tell what time is shown on it.
  • 0:06 - 0:08
    First thing, when we look at a clock,
  • 0:08 - 0:10
    we have two hands and that's because time
  • 0:10 - 0:12
    is told in two parts.
  • 0:12 - 0:14
    Time is told in hours,
  • 0:16 - 0:17
    that's part.
  • 0:17 - 0:20
    And on a clock the hours are represented
  • 0:20 - 0:22
    by the short hand,
  • 0:22 - 0:24
    and then the other part is minutes.
  • 0:27 - 0:28
    And on an analog clock like this one,
  • 0:28 - 0:31
    minutes are represented by the long hand.
  • 0:31 - 0:33
    So let's look first at hours.
  • 0:33 - 0:34
    We have the short hand,
  • 0:34 - 0:38
    and it's between the six and the seven.
  • 0:38 - 0:40
    What that means is it's after 6 o'clock,
  • 0:40 - 0:43
    but not quite seven,
  • 0:43 - 0:44
    'cause the hour hand started at the top
  • 0:44 - 0:46
    and worked its way around and it's gone
  • 0:46 - 0:47
    past 6 o'clock,
  • 0:47 - 0:49
    but it's not seven.
  • 0:49 - 0:52
    So it's six something.
  • 0:52 - 0:53
    Six something.
  • 0:53 - 0:55
    It might be 6:15, might be 6:45.
  • 0:55 - 0:57
    We'll figure out the minutes next,
  • 0:57 - 0:59
    but we know it's after 6 o'clock
  • 0:59 - 1:00
    but not a seven.
  • 1:00 - 1:03
    So we'll put a six in our hours place.
  • 1:03 - 1:06
    Then for minutes we have this longer hand
  • 1:06 - 1:10
    which is pointing right here at this mark.
  • 1:10 - 1:12
    And minutes, again, start at the top
  • 1:12 - 1:14
    and work their way around.
  • 1:14 - 1:18
    But now each of these
    little spaces is one minute.
  • 1:18 - 1:21
    So we can go one, two, three, four, five,
  • 1:21 - 1:23
    and when we get to this first square,
  • 1:23 - 1:25
    this first where this one is,
  • 1:25 - 1:27
    we've gone five minutes.
  • 1:27 - 1:28
    Let's keep going like that.
  • 1:28 - 1:31
    Six, seven, eight, nine,
  • 1:31 - 1:33
    10 at this next one,
  • 1:33 - 1:35
    and maybe you see a pattern here.
  • 1:35 - 1:37
    Every time we get to one of these numbers
  • 1:37 - 1:38
    or the squares, the bigger marks,
  • 1:38 - 1:41
    we've gone five more minutes.
  • 1:41 - 1:45
    So if we keep going this will
    be 15 minutes past the hour.
  • 1:45 - 1:47
    Keep going.
  • 1:47 - 1:48
    20.
  • 1:48 - 1:49
    Keep going.
  • 1:49 - 1:50
    25.
  • 1:51 - 1:53
    Now we can't go all the way to the six
  • 1:53 - 1:54
    because our minute hand stopped here.
  • 1:54 - 1:56
    It hasn't reached this part.
  • 1:56 - 1:59
    So after 25, we'll go
    back to counting by one,
  • 1:59 - 2:00
    is the one minute.
  • 2:00 - 2:01
    We have 25, 26, 27.
  • 2:04 - 2:07
    The minute hand has gone
    past 27 of these marks,
  • 2:07 - 2:11
    meaning that it is 27
    minutes past the hour.
  • 2:13 - 2:15
    Let's try another one.
  • 2:15 - 2:18
    The hour hand is between
    the four and the five,
  • 2:18 - 2:20
    which means it's after 4 o'clock.
  • 2:20 - 2:22
    It's some amount of minutes after four,
  • 2:22 - 2:25
    but it is not yet five.
  • 2:25 - 2:27
    And now let's look at our minute hand.
  • 2:27 - 2:30
    The longer hand represents minutes.
  • 2:30 - 2:32
    So the minute hand started at the top
  • 2:32 - 2:34
    and it's gone five, 10, 15,
  • 2:36 - 2:37
    not quite to 20,
  • 2:37 - 2:40
    so let's go back to 15
    and then count by ones.
  • 2:40 - 2:42
    16, 17, 18, 19.
  • 2:44 - 2:47
    Our minute hand lines up to 19.
  • 2:48 - 2:51
    So it is 19 minutes after four, or 4:19.
  • 2:55 - 2:57
    On this one I encourage
    you to pause the video
  • 2:57 - 3:01
    and see if you can figure out the time.
  • 3:01 - 3:03
    Okay, let's try it together now.
  • 3:03 - 3:07
    So the hour hand, between
    the seven and the eight.
  • 3:07 - 3:10
    So it's after seven, but not quite eight,
  • 3:10 - 3:13
    and by looking at the hour hand we can see
  • 3:13 - 3:14
    it's quite a bit after seven 'cause
  • 3:14 - 3:16
    it's almost eight.
  • 3:16 - 3:17
    And looking at the minute hand,
  • 3:17 - 3:19
    confirms that the minute hand's gone
  • 3:19 - 3:20
    all the way to here.
  • 3:20 - 3:23
    It's almost back to the top.
  • 3:23 - 3:26
    And that minute hand, starting at the top,
  • 3:26 - 3:28
    has gone five, 10, 15, 20,
  • 3:30 - 3:31
    25, 30, 35, 40,
  • 3:33 - 3:36
    45, and one more, 46 minutes past.
  • 3:39 - 3:41
    46 minutes past seven.
  • 3:42 - 3:43
    The time is 7:46.
