13. Time

14. The Hands of Time 60 5
There are 60 minutes on a clock face. Skip count by fives to count the minutes with me. 55 10 15 50 20 45 25 40 35 30

15. The Hands of Time
Count the numerals on the clock. There are only 12 hours on a clock face. So, the hour hand is a short hand.

16. “Minute” is a long word. The minute hand is the longer hand.
“Hour” is a short word. The hour hand is the shorter hand.
hour

17. When the minute hand is pointing to 12, read the time as “o’clock”
When the minute hand is pointing to 12, read the time as “o’clock”. In this case, the hour hand is pointing to the 3 and it is “three o’clock”.

18. Four Quarters
If we were to slice the clock into 4 equal sections, we would have 4 QUARTERS. Each quarter would represent a 15 minute section.

19. A Quarter After
When the minute hand is pointing to the numeral 3, we say that the time is “A quarter after/past _____.” Here, the clock shows a quarter past seven, or 7:15.

20. A Quarter Til/To
When the minute hand is pointing to the numeral 9, we say that the time is “A quarter til/to _____.” Here, the clock shows a quarter to five, or 4:45.

21. Half Past
When the minute hand is pointing to the numeral 6, we say that the time is “Half past _____.” Here, the clock shows half past 2, or 2:30. Notice how the hour hand is half-way in between the 2 and the 3.

22. AM/PM 12:00 AM is MIDNIGHT (We are sleeping)
12:00 PM is NOON (lunchtime)
When we say AM, we are referring to the hours before NOON.
When we say PM, we are referring to the hours past NOON.

23. Important Facts About Time
60 seconds= 1 minute
60 minutes= 1 hour
24 hours= 1 day
30 minutes= 1 half hour
