Look at the clock. Find the missing numbers to
tell the time in different ways. It is 35 minutes past what. It is 25 minutes to what. Pick the clock that shows the
same time.
To begin with, we’re shown an
analog clock that we need to look at. What time does it show? Now, often on an analog clock,
we’ll have two hands, the hour hand and the minute hand. But can you see this very thin
red hand here? This is called the second
hand. And it goes quite quickly
around the clock face. But all we need to tell the
time are the two black hands, the hour and the minute hand. So we’re going to ignore this
thin hand here.
To begin with, let’s look at
the minute hand. That’s the longer hand on our
clock. Where’s it pointing? We can see that it is here,
pointing to the number seven. Now, we know that at an o’clock
time, the minute hand will be pointing to the number 12. So how many minutes have gone
by to go from the number 12 all the way round to the number seven? It’s five minutes between one
number and another number on the clock face. So let’s skip count in fives to
see how many minutes past it is. Five, 10, 15, 20, 25, 30,
35. When the minute hand points to
the number seven, it’s 35 minutes past something. And that’s where we get our
first time that we need to fill in. It is 35 minutes past what.
To find the missing number, we
need to look at the hour hand. It’s pointing in between the
numbers four and five. What does this mean? We know that at 4 o’clock, it
would’ve pointed exactly to the number four. So it’s already gone past 4
o’clock, but it hasn’t reached 5 o’clock yet. So we can fill in our first
missing number. The time is 35 minutes past
four. Now, there’s another way we can
say this time. We’ve gone past 4 o’clock. But as we’ve said already,
we’re on our way to 5 o’clock.
Our next sentence says it is 25
minutes to something. But as we’ve said already, we
know that the next o’clock time is going to be 5 o’clock. But let’s just take a moment to
see why there are 25 minutes to 5 o’clock. At 5 o’clock, the minute hand
is going to have to travel all the way around back up to the number 12. And again, we can skip count in
fives to see how many minutes this is. There are five, 10, 15, 20, 25
minutes until 5 o’clock. That’s where the number 25
comes from here.
Now, which of these two digital
clocks shows the same time as the one we’ve been talking about? Now, we need to think carefully
here because we might see the numbers 4:35 in this second time and think, “Well,
this must show 35 minutes past 4.” Or we might see the numbers
five and 25 in this first time. And I think that it has
something to do with 25 minutes to 5. What do the digits that come
after the two dots on a digital time tell us? Is it the number of minutes
past an o’clock time or the number of minutes to the next o’clock time? They show the number of minutes
past. And so if it’s 35 minutes past
4, the time is 4:35. We read the time on the analog
in several different ways. It is 35 minutes past 4. It’s also 25 minutes to 5. And the clock that shows the
same time is the one that says 4:35.
