The clock shows the time at which
Liam went to bed. Write down the time using “AM” or
“PM.”

We are shown a picture of a clock
here, and we’re told that it shows the time at which Liam went to bed. So, we can imagine him going to bed
looking up at the wall and seeing this time. What time is it? Well, the long minute hand is
pointing up to the number 12. This shows us that it’s a start of
a new hour. This is an o’clock time. And we can also see that the hour
hand is pointing to the number 10. It’s 10 o’clock. And we can write 10 o’clock as a
digital time by writing the hours first, which is 10, and then the number of
minutes. And because it’s a new hour, no
minutes have gone by yet. So, this is how to write 10 o’clock
as a digital time.

Now, we could just write the time
like this, but our question tells us we need to write it using AM or PM. In other words, the answer to our
question is either going to be 10 o’clock AM or 10 o’clock PM. Do you remember what these little
letters stand for? We know that a day is made up of 24
hours. And during this time, the hour hand
goes twice all the way around the clock face. It goes round once during the 12
hours in the morning, this is from midnight to midday, and once during the 12 hours
from the middle of the day through to midnight. This covers the afternoon, the
evening, and the night.

So, we know that Liam’s clock is
going to look like this twice in the day. It’s going to show 10 o’clock in
the morning, but also there’s a 10 o’clock at night. How can we tell which time is
which? This is where the letters AM and PM
come in useful. We use the letters AM to represent
morning times. These are all the times from
midnight until just before noon. And we use the letters PM to
represent afternoon and night times. These are all the times from 12
noon until just before midnight.

Now, there’s one piece of
information in the first sentence that’s going to help us here. The clock shows the time at which
Liam went to bed. Now, unless he’s been awake all
night and he’s gone to bed in the morning, which isn’t very common, it’s probably
fair to think that Liam has gone to bed at 10 o’clock at night. We know that 10 o’clock AM would be
10 o’clock in the morning. And so, we can say that the time
that Liam went to bed is 10 o’clock PM.
