FACTS ABOUT TIME Time is the ongoing sequence of events taking place. The past, present and future. We measure time using seconds, minutes, hours, days, weeks, months and years. Clocks measure time. www.iPracticeMath.com

TELLING TIME TO THE HOUR AM/PM VS. 24 HOUR CLOCK Normally the time is shown as Hours: Minutes www.iPracticeMath.com There are 24 Hours in a Day and 60 Minutes in each Hour.

THE HANDS OF TIME The long hand is the minute hand. The short hand is the hour hand. www.iPracticeMath.com

THE HANDS OF TIME 55 50 60 5 10 15 There are 60 minutes on a clock face. 20 45 40 25 35 30 www.iPracticeMath.com

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. www.iPracticeMath.com

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

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”.

Now the minute hand is pointing to 12 and the hour hand is pointing to the 5. So, we read the time as “five o’clock”.

FOUR QUARTERS A clock divided into 4 equal sections, 4 QUARTERS. Each quarter would represent a 15 minute section. www.iPracticeMath.com
