1 Make the number cards using cardboard. You can make more than number cards shown
above.

2 Pupils are divided into several groups.


3 Group 1 is given card numbers written in numerals.

4 Group 2 is given card numbers written in words.

5 Pupils who get the numbers would look for numerals and words that match the cards in their
hands.

6 Pupils who have found their matches would stand before the class with their number cards in
their hand.

7 Other pupils would respond whether the matches to the number cards are right or wrong.

SMART NOTES



1. There are two ways to tell time: 3. Relationships between units of time:
(a) The 12-hour system
(i) a.m. – morning 1 minute = 60 seconds
(ii) p.m. – afternoon or evening 1 hour = 60 minutes
(b) The 24-hour system 1 day = 24 hours
(i) in numerals = 2250 hours 1 week = 7 days
(ii) in words = twenty-two f fty hours 1 year = 12 months
1 decade = 10 years
2. Duration = ending time – starting time
Ending time = starting time + duration 1 century = 10 decades
Starting time = ending time – duration 1 century = 100 years

(For the calculation of duration that involves 4. A leap year is a year that has an extra day
the number of days, one additional day compared to the normal years. A leap year
has to be added to the number of days in occurs once every four years in February.

counted.)
