Understanding hours and minutes


In Class 2, students begin learning about the concept of time. Time is an important measurement that allows us to determine the duration of activities, the sequence of events, and ensure that we are organized in our daily lives. One of the fundamental aspects of learning about time is understanding hours and minutes.

The basics of timing

Time is measured in units. The two basic units of time that we use in our daily lives are the hour and the minute. In order to tell time on a clock it is important to understand how these units work and relate to one another.

What is an hour?

An hour is a unit of time that is equal to 60 minutes. There are 24 hours in a day. Hours can be represented on both analog and digital clocks. On an analog clock, the small hand represents the hour.

1 hour = 60 minutes

For example:

If the time is 2:00 PM, then in one hour it will be 3:00 PM.

What is a minute?

Minute is a small unit of time. There are 60 minutes in an hour. In an analog clock, minutes are indicated by a long needle.

1 minute = 60 seconds

For example:

If the time is 3:15, then after 15 minutes the time will become 3:30.

How to read an analog clock

An analog clock has two main hands:

  • The hour hand, which is smaller and indicates the current hour.
  • The minute hand, which is longer and points to the current minute.

The analog clock face is divided into 12 segments, each of which represents an hour. Each hour is divided into 5 segments, each of which represents 5 minutes. To read the clock:

  1. Pay attention to where the hour hand is pointing. This will tell you the current hour.
  2. Pay attention to where the minute hand is pointing. Count the number of sections from the top (12), each section is 5 minutes long.
Example: 
If the hour hand is at 3 and the minute hand is at 12, the time is 3:00.
If the hour hand is at 4 and the minute hand is at 6, then the time will be 4:30.

Understand with examples

Let us take some examples to better understand how to tell time using an analog clock.

Example 1

Imagine the hour hand is between 7 and 8, and the minute hand is at 6.

The time is 7:30. The hour hand is between 7 and 8, indicating 7 o'clock, and the minute hand is at 6, indicating 30 minutes.

Example 2

Imagine the hour hand is straight at 5, and the minute hand is at 12.

The time is 5:00 PM. The hour hand is directly at 5, and the minute hand is at 12, indicating 0 minutes past the hour.

Example 3

Imagine the hour hand is a little past 9, and the minute hand is at 1.

The time is approximately 9:05 AM. The hour hand is slightly past 9, indicating that it is still the 9th hour, and the minute hand is at 1, indicating that it is 5 minutes past the hour.

Digital watches

Unlike analog clocks, digital clocks display time using numbers. They show hours, minutes, and sometimes seconds using numerals such as 3:45 or 11:00. The number before the colon represents the hour, and the number after the colon represents the minutes.

Example: 
8:30 means 8 hours and 30 minutes past 8.
14:45 means 2:45 PM.

Why learning time is important

Understanding how to tell time helps in several ways:

  • Daily Routine: Knowing the time helps us to manage daily activities like waking up, going to school, meal and bed time.
  • Appointments: We need to know the timings to attend meetings or doctor's appointments on time.
  • Planning: Understanding time helps us plan our work and leisure activities effectively.

Practice over time

It takes practice to master understanding hours and minutes. Here are some practice tips:

  • Clock Practice: Using a toy clock, practice setting the time by moving the hands according to the given time.
  • Discuss time: Talk about the start and end times of daily activities, such as, “We start dinner at 6:00 and have dessert at 6:30.”
  • Time games: Play games that involve solving different time puzzles, like matching clock faces to digital time.

Conclusion

Understanding hours and minutes is a fundamental skill for young students as they progress in their ability to manage time efficiently. Through hands-on exercises and engaging activities, learning about time becomes an enjoyable and valuable experience. By reinforcing these basics, students build a strong foundation for more advanced concepts of time in the future.
