You also know that there are 12numbers placed around the face of
the clock. Each number stands for a
certain number of minutes past the
hour. If you know how to count by
5s then you know how to figure out
how many minutes past the hour it is.

For example: When the minute hand is on
the 6, that means that it is 30 minutes past
the hour . We can use multiplication to helpout too. 6 X 5 = 30

The minute hand goes around once for
every hour. When the minute hand is on the
12, the hour hand is pointing exactly at anhour. When it has gone exactly between the
hours, it is called half-past the hour.
When the minute hand points to the 3, it hasgone a quarter of the way around, so its a
quarter past the hour.

Lets say that the hour hand is past the 1, in
fact more than halfway to the 2, the minute
hand points to the 7, meaning that its 35minutes past the hour. Thats a little more
than half-past one.
You can also call this 25 before 2.

How do you know that?
You can count by fives while you imagine the
minute hand continues around to the 12. It
will take 5 minutes to get to the 8, 10 to getto the 9, then 15, 20, 25 minutes to get to
the 12. So its 25 minutes until the next
hour, which is 2.

The hardest times to read are when its just
before an hour. Thats when its important
to understand how the hour hand moves.Suppose its just five minutes before 2
oclock. Then the hour hand is also at the 2,
and the minute hand is at the 11. But weread this as 1:55, not 2:55, because its 55
minutes after 1 and 5 minutes before 2.

The last step will be to learn to read minutes
between the fives. That can wait until
youre ready. Its best if you have a clockthat has a little mark at every minute.
Usually we dont need to be that exact. If
the minute hand points near the 7, but notexactly, you can say its about 1:35.

The big numbers
The big numbers on the clock tell what
number hour it is when the hour hand points
there, but each one also stand for fiveminutes. It will be helpful to get a clock
with the minute markings on it. Once you
get used to it, you should be able to imaginethe minute numbers around the outside, by
just counting by fives.
