What is an Analog Clock? and what are the hands on an analog clock called?

Zuri and Freddie are exploring their local landfill and finding lots of exciting items! One of the items that they find is a pretty blue analog clock. However, they aren’t familiar with this type of clock and need to learn more about it’s features to understand how to turn off it’s alarm. Below we’ll learn more about what an analog clock is and what are the hands in a clock called.

Analog vs digital clock

What is the difference between an analog clock and a digital clock? An analog clock displays the time with moving arrows usually around a circle. A digital clock is usually rectangular and displays the time using digits.

Analog clock practice

Take a look at this picture of an analog clock, what do you notice?

What are the hands on an analog clock called? The analog clock has arrows that move around the clock from one to twelve to show the time. There are two arrows that show the hour and minute on the clock, these are also called the analog clock hands.

The hour hand is the shorter arrow, you might remember this because the word hour is short.

The minute hand is the longer arrow on the clock. You might remember this because the word minute is longer than the word hour.

Which hand on a clock is the hour hand?

Remember that the hour hand is the shorter arrow on an analog clock. Take a look at this picture, which number is the hour hand pointing to?

The hour hand, or the shorter arrow, is pointing to the number four.

Which hand on an analog clock is minutes?

Remember the minute hand is the longer arrow on a clock. Take a look at this picture, which number is the minute hand pointing to?

The minute hand, or the longer arrow, is pointing to the number twelve.

Analog clock: Face and hands – Summary

Remember, an analog clock has…

  • Numbers that go around the clock from one to twelve.

  • As time moves forward the arrows move around clockwise.

  • The hour hand is the shorter arrow.

  • The minute hand is the longer arrow.

  • AM refers to something that happens before 12:00 noon.

  • PM refers to something that happens after 12:00 noon.

Transcript Analog Clock: Face and Hands

Zuri and Freddie are having a fun day searching through items at their local landfill when they hear something odd. : "Freddie, there's something down here!" : "I found it! Look what a pretty blue it is... what... is it?" Zuri and Freddie have found an analog clock. Today we will learn about the features of an analog clock, such as its face and hands. "Analog Clock: Face and Hands" : "Uh, Freddie? Why is it making that noise?" : "More importantly, how do we get it to STOP?" Let's take a look at the analog clock that Zuri and Freddie have found. This type of clock displays the time with moving arrows, typically, around a circle. It's different from the rectangular digital clock, which displays time with digits instead of arrows. Today we'll focus on the features of an analog clock. The analog clock shows numbers one through twelve around the circle. The clock starts at one and ends at twelve. An analog clock has arrows that move to show the time, also called hands. The first arrow is the hour arrow or the short hand. You can rermember this because the hour hand is short, and so is the word "hour". The next arrow is the minute arrow, or minute hand. You can remember this because the minute arrow is longer, and the word "minute" is longer than the word "hour". Which arrow is pointing to the number three on Zuri and Freddie's clock? (...) The shorter arrow is pointing to the number three, so the HOUR HAND is pointing to the number three. Which arrow is pointing to the number twelve on Zuri and Freddie's clock? (...) The longer arrow is pointing to the number twelve, so the MINUTE HAND is pointing to the number twelve. Once the minute hand makes it all the way around the clock, sixty minutes, or, one hour has passed. On a digital clock, there is usually a label that says AM or PM. That tells us whether it's before 12:00 noon, AM, or after 12:00 noon, PM. There isn't a label on analog clocks that shows AM or PM (...) So, it's important to pay attention to what is happening at that time to know if the time is AM or PM. For example, if Freddie says he's going to play outside at three using an analog clock we know it is 3:00 PM, or afternoon, NOT 3:00 AM, or morning. If the analog clock says nine while Zuri eats breakfast, do you think it is 9:00 AM or PM? (...) (...) If Zuri is eating breakfast it is probably in the morning. That means she will be eating at 9:00 AM. 9:00 AM shows something that is happening in the morning while 9:00 PM shows something that is happening at night. Let's summarize. Today we explored an analog clock. We learned that it has numbers from one to twelve all around it, and that as time moves forward the arrows move around the clock in a direction called clockwise. We learned about the hour and minute hands, and explored the difference between AM and PM. Let's see if Zuri and Freddie have figured out their analog clock yet. : "DID YOU MAKE IT STOP YET?"

Analog Clock: Face and Hands exercise

Would you like to apply the knowledge you’ve learned? You can review and practice it with the tasks for the video Analog Clock: Face and Hands .
  • Can you find all of the analog clocks?

    Hints

    Does the clock have a long hand and a short hand?

    Numbers above 12 are not on analog clocks.

    Solution

    These are the analog clocks!

    They:

    • are usually circular
    • have a long (minute) hand and a short (hour) hand
    • display the numbers 1 to 12

  • Can you match the times?

    Hints

    Think about which hand is which. What is the blue hand showing? What is the red hand showing?

    On these clocks, the blue hand is the longer minute hand and the red hand is the shorter hour hand.

    This clock shows 2 o' clock. The long minute hand is at 12 and the short hour hand is at 2.

    Solution
    • The first clock shows three o' clock. The long minute (blue) hand is at 12 and the short hour (red) hand is at 3. When the long minute hand is at 12 it is always an o' clock time.
    ___________________________________________________________________

    • The second clock shows 12 o' clock. Both hands are at 12.
    • The third clock shows 6 o' clock. The long minute hand is at 12 and the short hour hand is at 6.
    • The fourth clock shows 1 o' clock. The long minute hand is at 12 and the short hour hand is at 1.
  • Do you know the features of an analog clock?

    Hints

    Can you use this clock to help you?

    What shape is the clock? Which numbers are displayed?

    Remember, the length of the hands help us to remember what each one does. On this clock, the blue hand is the minute hand and the red hand is the hour hand.

    Solution

    1. An analog clock is usually in the shape of a circle.
    It displays numbers one through twelve around the edge.

    2. It has two hands.
    The hands move around in a clockwise direction to show the time.

    3. The long hand is also called the minute hand.
    The short hand is also called the hour hand.

    4. The analog clock does not display AM or PM, so it is important to pay attention to what is happening to know what time of day it is.

  • Can you order Zuri's day?

    Hints

    Does the picture give you a clue as to whether it is morning or evening?

    Remember 12 noon is in the middle of the day then the analogue clock goes back to 1:00pm.

    Solution

    Zuri got up at 7 o' clock and brushed her teeth at 7 o' clock, but one of them happened at 7:00 AM and one of them happened at 7:00 PM. You normally get out of bed in the morning, so Zuri got up at 7:00 AM. She is wearing her pj's and it looks like the evening when she is brushing her teeth, so this event happened at 7:00 PM.

    _________________________________________________________________

    • Zuri got up at 7:00 AM
    • Zuri ate her breakfast at 8:00 AM
    • Zuri ate her lunch at 12:00 noon which is 12:00 PM
    • Zuri played outside with Freddie at 2:00 PM
    • Zuri brushed her teeth at 7:00 PM
    • Zuri went to sleep at 8:00 PM
  • Can you label this analog clock?

    Hints

    Remember, the length of each hand gives us a clue about the job it does.

    This clock is showing the time 9 o' clock because the long minute hand is at 12 and the short hour hand is at 9.

    Solution

    Here is the fully labelled analog clock.

    • We can remember that the long hand is the minute hand because minute is a longer word than hour.
    • We can remember that the short hand is the hour hand because hour is a shorter word than minute.
    • The numbers move around from 12 in a clockwise direction.
    • The time displayed on the clock is 3 o' clock.
  • Can you solve Freddie and Zuri's puzzle?

    Hints

    Remember when the minute hand goes all the way around, the hour hand just moves from one number to the next.

    If it is going counter-clockwise, then the hour hand will move back one number.

    If we're starting at 3:00 and going around the clock once, we are adding on one hour.

    Solution

    The correct time is 5 o' clock!

    • The clock started at 3 o' clock.
    • Freddie and Zuri wound it forwards one hour to 4 o' clock.
    • They then wound it forwards two more hours to 6 o' clock.
    • Finally they wound it backwards one hour to 5 o' clock.
