Let's Practice 
Once upon a time, there was a little girl named Mia. Mia loved playing outside with her friends and going on adventures. One day, her mom said they were going to have a special picnic in the park on Wednesday.
"But how will we remember when Wednesday is?" Mia asked, looking puzzled. Mom smiled and pointed to a colorful calendar hanging on the wall. "We'll use this!" she said.
She showed Mia the days of the week and the names of the months. Then Mom circled "Wednesday, 22nd May" on the calendar."Now we know when our picnic is!" Mom said cheerfully. And so, Mia learned that the calendar was like a magical guide that helped her family plan fun adventures together.
Imagine you have a special book that helps you know what day it is, plan events, and remember important dates like birthdays and holidays. This special book is called a calendar!
Isn't it cool how the calendar helps us keep track of time and remember special moments?
Let's talk about Mia's family.
Consider Lily and her brother.
Birth Certificate is a special document which contains important information about Lily's birth, like her birth date and her parents' names, making it a special keepsake for her family.
These simple examples help us understand how ages are connected within families and how we can figure out different ages and dates using basic math.
Time is a way to measure and quantify the duration or sequence of events. It's a concept that helps us understand when things happen, how long they last, and in what order they occur.
A clock is used to measure time. A clock has two hands— the short hand called the hour hand and the long hand called the minute hand.
60 minutes = 1 hour
1 day = 24 hours
In the clock shown alongside, the hour hand is between 9 and 10 and the minute hand points to 6. The coloured part shows that the long hand or minute hand has moved half way round.
When the minute hand moves half way round the face of the clock, half an hour has passed and we say that it is half past nine.∴ Half past nine can also be written as 9:30.
60 minutes = 1 hour
30 minutes = Onehalf of an hour
Observe the following clocks
When the minute hand has moved past 6, we say the time in the following two ways:
1. First Way : The hour hand is between 4 and 5, so the time is after 4 o’ clock. The minute hand is at 7. Starting at 12 and counting ahead by 5s to 7, we get 35 minutes.Thirtyfive minutes past 4 or 4:35
So, we say that the clock shows the time 35 minutes after 4 or 35 minutes past 4.
2. Second Way: The hour hand is between 4 and 5, so the time is before 5 o’ clock. The minute hand is at 7. Starting at 12 and counting back by 5s to 7, we get 25 minutes. We write 25 minutes to 5 to tell the time because there are 25 minutes left to 5 o’ clock.Twentyfive minutes to 5
Let us read time on the clocks given below:
The minute hand has moved one quarter (onefourth) of the circle in moving from 12 to 3.So, 1 / 4 of an hour = 15 minutes.
Examples:
(i) Number of Sundays ______________________________
(ii) Write the dates in this month that are Thursday ___________________________
(iii) Three days after July 22 is July _____________________.
The day on this date is _____________________
(iv) A school closes on July 7 for 15 days. The date on which the school will open is _____________________
Sol:
(i) No. of Sundays = 4.
(ii) The dates that are thursday in this month are 4, 11, 18, 25.
(iii) Three days after July 22 is July 25, and the day on this date is thursday.
(iv) A school closes on July 7 for 15 days. The date on which the school will open is July 22.
2. Match the activity with the statement shown in the picture. Write the time and draw the minute hand and the hour hand wherever
it is required.
