Describing Time Using Quarter Past and Quarter to (2)
Tell time to the quarter-hour, using the language of ‘past’ and ‘to’ (ACMMG039)
LO: To tell time to the quarter and half hour.
Know:
the basic units of time (seconds, minutes, hours, days, weeks, years)
the minute hand and hour hand have distinct actions and functions
how to read o’clock and ‘half past’ times on analogue and digital clocks
digital times for o’clock and half-past are :00 and :30.
there are five divisions between each of the numbers of the analogue clock and can count around the clock to 60.
zero is also at 12, along with 60 on an analogue clock.
Understand:
that we can tell time to the quarter and half hour.
Do:
I can tell digital and analogue time to the quarter and half hour.
A clock can be broken down into quarters.
Each quarter of a clock is 15 minutes, so we know that when the big hand of the clock hits ‘3‘, that is quarter past the hour. When the big hand hits the ‘6‘ it is halfway around the clock, which makes it half past the hour. When the big hand hits the ‘9‘ it means there’s a quarter of the clock to the next hour.
So when it is 15 minutes after an hour (2:15), we can say quarterÂ past 2.
So when it is 15 minutes until the next hour (2:45), we can say quarter to 3.
When it is 30 minutes into an hour (2:30), we can also use half-past to describe the time.
For example, we can describe this time as half-past 2.
