MEASURES OF TIME

1. Measures of time
   The smallest unit of time is normally the second, followed by the minute and the hour.

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

7 days = 1 week

28/29/30/31 days = 1 month depending on the nature of month and the year.

12 months = 1 year

The measures of time may be introduced orally with the provision of a tactile watch.

When the child is comfortable with ideas of second, minute and hour, other related

ideas such as number of hours in a day, number of days in a week, number of days and

weeks in a month and the number of days, weeks and months in a year may be taught.

2. Ordinary year
   The amount of time the earth takes to make one complete revolution about the sun is
   1 year which is equivalent to 365 days. Thus an ordinary year constitutes 365 days.

The idea of an ordinary year may be taught to the child orally, explaining the number

of days in each month.
