  • What is Time?

    Knowing the concept of time is important in planning our daily activities, which include eating, playing and sleeping. This is a concept we use in our daily lives. We have a special tool referred to as a clock that tells us what time is it

    How to read Time?

    The hands on the clock are used to tell time. The clock has three hands: the second hand, the minute hand and the hour hand.

    Steps to read Time:

    • Look at the short hand for the hour.
    • Look at the long hand for the minutes.
    • If there's a fast-moving hand, that's for seconds.

    So, you see where the hands point, and that tells you what time it is. It's like a special code on the clock!"

    To write time, first we write the hour, then positioned a colon (:) and write the minutes. For instance, In 4:20, 4 represents hours and 20 represents mins.

    Let's see different hands on a clock:
