This term we have been looking at different clocks and how to tell the time accurately. We discussed the following…
Analogue Clocks – they use hands to show us the minutes and the hours. The hour hand is short and the minute hand is long.
Digital clocks – use numbers (digits) to show the time
AM – stands for Ante Meridiem which is Latin for “before midday”.
PM – stands for Post Meridiem which is Latin for “after midday”
Some of us were a little confused on whether it was ‘am’ or ‘pm’ when the time is 12:00 in the middle of the day and also 12:00 in the middle of the night. We now know that when it is 12:00pm it is midday and the beginning of ‘pm’. When it is 12:00am it is midnight and the beginning of ‘am’. Here is a diagram to help explain this.
As a class we have been practising how to read different times using the analogue clocks and using the correct language.
o’clock – when it is exactly on the hour. The minute hand is always on the 12 (0 minutes)
half past – when half an hour or 30 minutes has passed from the hour. The minute hand is always on the 6 (30 minutes)
quarter past – when a quarter of an hour or 15 minutes has passed from the hour. The minute hand is always on the 3 (15 minutes)
quarter to – when there is a quarter of an hour until the next “o’clock” or new hour. The minute hand is always on the 9 (45 minutes)
We will continue to use this language daily and practise reading the time throughout the day.

What do you find challenging when reading the time?
Can you list some places that you see both analogue and digital clocks in everyday life?
Write down the following times as a digital time and then using words.
1. What time you got out of bed this morning
2. What time recess finishes at school
3. What time lunch eating begins
4. What time you normally go to bed
5. An activity of your choice.
