Starting at 12, we count clockwise around the clock to tell us the minutes past the hour. Each number represents 5 minutes.
5 past 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
If the minute hand is pointing to the 2 and the hour hand is pointing between the 10 and the 11, what time is it? Think carefully – which number has the hour hand just gone past

If the minute hand is pointing to the 5 and the hour hand is pointing between the 7 and the 8, what time is it? Think carefully – which number has the hour hand just gone past
5 past 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
If the minute hand is pointing to the 4 and the hour hand is pointing between the 11 and the 12, what time is it? Think carefully – which number has the hour hand just gone past
5 past 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
Starting at 12, we count anti clockwise around the clock to tell us the minutes to the hour. Each number represents 5 minutes.

We can tell the time past the hour to the nearest minute by counting clockwise round the clock in fives, then counting
until we reach the exact time.
5 past 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
The minute hand is 3 minute after the 2 so it must be 13 minutes past the hour.
5 past 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
What time is it?

We can tell the time to the hour to the nearest minute by counting anticlockwise round the clock in fives, then counting on in single minutes until we reach the exact time.
5 to 10 to 15 minutes to (quarter to) 20 to 25 to
The minute hand is 2 minute after the 9 so 5… 10… 15… 17 it must be 17 minutes to the hour.
5 to 10 to 15 minutes to (quarter to) 20 to 25 to
The minute hand is 3 minutes after the 2 so 5… 10… 15… 20… 23 it must be 23 minutes to the hour.

There are 24 hours in one day. Those 24 hours are divided into two parts. Each part is 12 hours long. These parts are called A.M. and P.M.
The first part of the day goes from midnight to noon. This is the morning and we call it a.m. The second part of the day goes from noon to midnight. It is the afternoon and evening. We call in pm.
You have walked to school. Is it a.m. or p.m.? You have just eaten your tea. Is it a.m. or p.m.? You are playing in the pool after school. Is it a.m. or p.m.?

If a film started at 12:00 p.m. and lasted 2 hours, when would it end?
2:00 p.m.
If a film started at 5:00 p.m. and lasted 1 hour and 20 minutes, when would it end?
First, I added on the hour so 5:00 p.m. became 6:00 p.m. Then I added on the 20 minutes so 6:00 p.m. became 6:20 p.m.

In this activity, you will need to carefully decide how you will solve the problems. Look at the examples.
It takes 55 minutes to cook a pie, if I start to make it at 11.30am, what time will it be ready to eat?
It takes 55 minutes to cook a pie, if I start to make it at 11.30a.m., what time will it be ready to eat? I need to add 55 minutes onto 11:30 a.m. 12:25 p.m.

hours and 15 minutes long. If I watch both DVD’s one after the other, how long will I be watching? I need to add the lengths of the DVD’s together. 2 hours add 2 hours is 4 hours 15 minutes add 15 minutes is 30 minutes So… it will take 4 hours and 30 minutes to watch the DVDs
