ACTIVITY 1 – O’CLOCK AND HALF PAST
O’ CLOCK AND HALF PAST The minut ute e hand nd 12 (the long hand) 11 1 tells us how many 2 10 minutes The hour 9 3 hand ( the short hand) 8 tells us the 4 hour 7 5 6
When the minute hand points to the 12 11 1 12 it is ……..o’clock. 2 10 9 3 8 4 7 5 6
12 If the minute 11 1 hand is pointing 2 10 to the 12 9 and the hour 3 hand is pointing to the 3, 8 4 7 what time is it? 5 6
If the minute 12 hand is pointing 11 1 to the 12 2 10 and the hour hand is pointing 9 3 to the 9, 8 4 what time is it? 7 5 6
When the 12 11 1 minute hand points 2 10 to the 6 it is half 9 3 past the hour. 8 4 7 5 6
If the minute hand is pointing to the 6 12 11 1 and the hour hand is pointing 2 10 between the 2 and the 3, 9 3 what time is it? 8 Think carefully – 4 which number has 7 5 6 the hour hand just gone past
Use this to complete activity 1. Maths tasks page 1 If the minute hand is pointing to the 6 12 and the hour hand 11 1 is pointing 2 10 between the 8 and the 9, 9 3 what time is it? Think carefully – 8 4 which number has 7 the hour hand just 5 6 gone past
ACTIVITY 2 – QUARTER PAST AND QUARTER TO
If the minute hand is pointing to the 3 It is quarter past the hour
If the minute hand is pointing to the 3 and the hour hand is pointing between the 12 and the 1, what time is it? Think carefully – which number has the hour hand just gone past
If the minute hand is pointing to the 3 and the hour hand is pointing between the 6 and the 7, what time is it? Think carefully – which number has the hour hand just gone past
If the minute hand is pointing to the 9 It is quarter to to the hour
If the minute hand is pointing to the 9 and the hour hand is pointing between the 10 and the 11, what time is it? Think carefully – which number is the hour hand coming to to
Use this to complete activity 2. Maths tasks page 2 If the minute hand is pointing to the 9 and the hour hand is pointing between the 1 and the 2, what time is it? Think carefully – which number is the hour hand coming to to
ACTIVITY 3 – TO 5 MINUTES
5 past Starting at 12, we count clockwise 10 past around the clock to tell us the minutes past the hour. Each 15 minutes past number represents 5 (quarter past) minutes. 20 past 25 past 30 minutes past (half past)
5 past If the minute hand is pointing to the 2 10 past and the hour hand is pointing between the 10 and the 11, what time is it? 15 minutes past (quarter past) Think carefully – which number has the hour hand just gone past 20 past 25 past 30 minutes past (half past)
5 past If the minute hand is pointing to the 5 10 past and the hour hand is pointing between the 7 and the 8, what time is it? 15 minutes past (quarter past) Think carefully – which number has the hour hand just gone past 20 past 25 past 30 minutes past (half past)
5 past If the minute hand is pointing to the 4 10 past and the hour hand is pointing between the 11 and the 12, what time is it? 15 minutes past (quarter past) Think carefully – which number has the hour hand just gone past 20 past 25 past 30 minutes past (half past)
5 to Starting at 12, we count anti clockwise around 10 to the clock to tell us the minutes to 15 minutes to the hour. Each (quarter to) number represents 5 minutes. 20 to 25 to
5 to If the minute hand is pointing to the 7 and the hour hand 10 to is pointing between the 11 and the 12, 15 minutes to (quarter to) what time is it? Think carefully – which number is the 20 to hour hand coming to to 25 to
5 to If the minute hand is pointing to the 10 10 to and the hour hand is pointing between 15 minutes to the 1 and the 2, (quarter to) what time is it? Think carefully – 20 to which number is the hour hand coming 25 to to to
Use this to complete activity 3. Maths tasks page 3 5 to If the minute hand is pointing to the 8 and the hour hand 10 to is pointing between the 5 and the 6, 15 minutes to (quarter to) what time is it? Think carefully – which number is the 20 to hour hand coming to to 25 to
ACTIVITY 4 – MINUTES PAST
5 past We can tell the time past the hour to the 10 past nearest minute by counting clockwise round the clock in 15 minutes past fives, then counting (quarter past) on in single minutes until we reach the exact time. 20 past 25 past 30 minutes past (half past)
5 past The minute hand is 3 minute after the 2 so 10 past it must be 13 minutes past the hour. 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
5 past What time is it? 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
5 past What time is it? 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
Use this to complete activity 4. Maths tasks page 4 5 past What time is it? 10 past 15 minutes past (quarter past) 20 past 25 past 30 minutes past (half past)
ACTIVITY 4 – MINUTES TO
5 to We can tell the time to the hour to the nearest 10 to minute by counting anticlockwise 15 minutes to round the clock in (quarter to) fives, then counting on in single minutes 20 to until we reach the exact time. 25 to
5 to The minute hand is 2 minute after the 9 so 10 to 15 minutes to 5… 10… 15… 17 (quarter to) 20 to it must be 17 minutes to the hour. 25 to
5 to The minute hand is 3 minutes after the 2 so 10 to 5… 10… 15… 15 minutes to 20… 23 (quarter to) 20 to it must be 23 minutes to the hour. 25 to
5 to What time is it? 10 to Think carefully, what hour is the 15 minutes to hour hand coming (quarter to) to… 20 to 25 to
5 to What time is it? 10 to Think carefully, what hour is the 15 minutes to hour hand coming (quarter to) to… 20 to 25 to
Use this to complete activity 5. Maths tasks page 5 5 to What time is it? 10 to Think carefully, what hour is the 15 minutes to hour hand coming (quarter to) to… 20 to 25 to
ACTIVITY 6 - AM AND PM
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.
Use this to complete activity 6. Maths tasks page 6 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.?
ACTIVITY 7 THE 24 HOUR CLOCK
The twenty four hour clock splits the day into 24 hours. The day starts at midnight which is written as 00:00. Five past twelve (midnight) is written as 00:05 One o’clock in the morning is 01:00, so five past one is 01:05
