Reinforcing the Concept

Performing the Activity

Group the pupils by 3 Groups. Let them answer the following..

a. There are 14 days.

How many weeks are there?

How did you get 2 weeks?

(14÷ 7 = 2 weeks)

​

b. There are 3 weeks.

How many days are there?

How did you get 21 days?

(3 weeks x 7= 21 days)

​

c. There are 60 days.

How many months are there?

How did you get 2 months?

(60 ÷ 30 = 2 months)

Processing the Activity

​

How did you come up with your answer?

Did you find it difficult/easy?

How many days are there:

-in a week?

- in a month?

- in a year?

• To convert days to weeks, divide the number of days by 7.
• To convert weeks to days, multiply the number of weeks by 7.

How do you convert days to months and vice versa?

• To convert days to months, divide the number of days by 30.
• To convert months to days, multiply the number of months by 30.

How do you convert days to years and vice versa?
