Digital Clocks

Digital clocks show us the time.

To tell time, we read the numbers or “digits.”


Telling time

The first 2 digits tell the hour.

The second 2 digits tell the minutes

12:30

It is twelve, thirty.


Telling time

12:30

The clock shows that 30 minutes have passed since it was 12 o’clock.


Telling time

12:30

Since there are only 60 minutes in an hour, it must be half way to the next hour.


Telling time

12:30

30 + 30 = 60. What time will it be in 30 more minutes?

Let’s look at another kind of clock to help us figure that out.

Analog Clocks

Can you use this clock to help?


Telling time

Though there are 24 hours in a day, there are only 12 numbers on a clock.

Each hour comes up twice a day.


Telling time

Analog clocks have two hands to tell time.

It takes 60 minutes for the big hand to go all the way around the clock face.

It takes 12 hours for the little hand to go all the way around the clock face.


Telling time

The little hand tells the hour.

The hour is seven. We write it like this.

7:__


Telling time

The big hand tells the minute.

A new hour begins every time the minute hand is at the 12.

7:

00


Telling time

Since the hour has just begun, we write the minutes like this.

Telling time

The numbers are in 5 minute intervals

Telling time

Some clocks use Roman Numerals


Telling time

This is a picture of the famous Big Ben in London

This is also an analog clock. It uses Roman Numerals.

This is one of the world’s largest clocks

Digital Clocks

The numbers are easier and faster to read.

These clocks are very popular today.

Review


Telling time

There are sixty seconds in a minute.

WOW!!!

There are sixty minutes in a hour.

But did you know that there are 3,600 seconds in a hour and 525,600 minutes in a year?


Telling time

Digital clocks show the time exactly as it appears.

The hours are shown by the two numbers before the colon.

The minutes are shown by the two numbers after the colon.
