Time

Time is a way of measuring how long things take or when things happen. It can be measured in hours, minutes, and seconds using clocks, or in days, weeks, months, and years using calendars.

 Key Concepts in Time for Class 3:
1. Reading the Clock:
– Analog Clock: Understanding the positions of the hour hand and minute hand to tell the time (e.g., 4:00, 2:30).
– Digital Clock: Reading time in numbers (e.g., 7:45).

2. Units of Time:
– 1 hour = 60 minutes
– 1 minute = 60 seconds
– 1 day = 24 hours
– 1 week = 7 days
– 1 year = 12 months

3. AM and PM:
– AM is the time from midnight (12:00 AM) to noon (12:00 PM).
– PM is the time from noon (12:00 PM) to midnight (12:00 AM).

4. Days of the Week and Months of the Year:
Learning to name the 7 days of the week and the 12 months of the year in order.

Reading time from a clock

Parts of a Clock:
1. Hour Hand (Short Hand):
– This hand tells the hour.
– It moves slowly around the clock and points to the current hour.

2. Minute Hand (Long Hand):
– This hand tells the minutes.
– It moves faster than the hour hand and completes one full circle in 60 minutes.

3. Numbers on the Clock (1 to 12):
– The numbers on the clock represent the hours.

Steps to Read Time from a Clock:

1. Look at the Hour Hand (Short Hand):
– First, see where the hour hand is pointing.
– If it is pointing exactly at a number (e.g., 3), that’s the hour. So, it is 3 o’clock.
– If the hour hand is between two numbers (e.g., between 4 and 5), the time is past 4 but not yet 5, so the hour is 4.

2. Look at the Minute Hand (Long Hand):
– Next, see where the minute hand is pointing. Each number on the clock also stands for minutes in intervals of 5.

– Here’s how the numbers correspond to minutes:
– 12 = 00 minutes (o’clock)
-1 = 5 minutes
– 2 = 10 minutes
– 3 = 15 minutes (quarter past)
– 4 = 20 minutes
– 5 = 25 minutes
– 6 = 30 minutes (half past)
– 7 = 35 minutes
– 8 = 40 minutes
– 9 = 45 minutes (quarter to)
– 10 = 50 minutes
– 11 = 55 minutes

Examples:

1. Time: 3 o’clock (3:00)
– The hour hand points exactly at 3.
– The minute hand points at 12, which means 0 minutes (o’clock).

2. Time: 4:30 (Half past 4)
– The hour hand is between 4 and 5 (closer to 4), so the hour is 4.
– The minute hand points at 6, which means 30 minutes (half past).

3. Time: 2:15 (Quarter past 2)
– The hour hand points at 2.
– The minute hand points at 3, which means 15 minutes (quarter past).

4. Time: 5:45 (Quarter to 6)
– The hour hand is between 5 and 6, so the hour is still 5.
– The minute hand points at 9, which means 45 minutes (quarter to 6).

Key Phrases to Remember:
– O’clock:When the minute hand is on 12 (e.g., 5:00).
– Quarter Past: When the minute hand is on 3 (e.g., 7:15).
– Half Past: When the minute hand is on 6 (e.g., 4:30).
– Quarter To: When the minute hand is on 9 (e.g., 8:45).

To read time when the minutes hands is at any numbers.

Understanding the Minute Hand:

The minute hand is the longer hand on the clock. It moves faster than the hour hand and tells us how many minutes have passed after the hour.

Important Points to Know:

  • One full circle of the minute hand equals 60 minutes.
  • The clock has 12 numbers, but each number represents 5 minutes.
  • To find how many minutes have passed, multiply the number by 5.

Steps to Read the Minute Hand:

  1. Look at Where the Minute Hand is Pointing:

    • Each number on the clock represents 5 minutes.
    • You can count in steps of 5 to know how many minutes have passed.

  2. Use the Multiplication Rule:

    • Multiply the number the minute hand points to by 5. This will give you the total minutes.

Day’s routine.

A day’s routine refers to the different activities you do throughout the day, from morning until night. Let’s break it down for Class 3 students, explaining how time is related to different parts of the day.

Parts of the Day:
1. Morning:
– The day begins in the morning. This is usually the time between 6:00 AM and 12:00 PM (noon).
– During the morning, we wake up, brush our teeth, have breakfast, and go to school.

2. Afternoon:
– The time from 12:00 PM (noon) to 4:00 PM is called the afternoon.
– In the afternoon, we are usually in school, have lunch, and do activities like playing or studying.

3. Evening:
– The evening is the time between 4:00 PM and 7:00 PM.
– During this time, we finish school, go home, do homework, play outside, and have dinner.

4. Night:
– The night is from 7:00 PM until midnight (12:00 AM).
– At night, we get ready for bed, read a book, or spend time with family. It’s also when we sleep.

Relating Routine to Time:

– AM (Ante Meridiem): This is the time from midnight to noon (12:00 AM to 11:59 AM). Morning activities like waking up and going to school happen during this time.
– PM (Post Meridiem): This is the time from noon to midnight (12:00 PM to 11:59 PM). Afternoon, evening, and night activities, like playing, having dinner, and sleeping, happen during this time.

Why is a Routine Important?

– A routine helps us stay organized and plan our day.
– It makes sure we have time for everything, including studying, playing, and resting.
