Time
Time is an important aspect of our daily lives. We use time to plan our activities, schedule our day, and keep track of important events. For young learners, understanding time starts with learning to read a clock, understanding daily routines, and understanding the concept of sequence and duration.
The basics of timing
Time is measured in different units such as seconds, minutes, and hours. These units help us understand short and long periods of time. For young students, the most common units are minutes and hours.
Understanding hours and minutes
An hour is like a big block of time. Imagine you are playing with building blocks. If a day is a big tower made of 24 blocks, each block would represent an hour. A minute is a small block of time. Think of each hour as being divided into 60 smaller blocks, which are minutes.
Each rectangle represents 1 hour of a 5-hour time segment.
Reading the clock
There are different types of watches, but two types are most common: analog and digital watches.
Analog clocks
Analog clocks have a face with the numbers 1 to 12 on the edge. They have two main hands, the hour hand and the minute hand. Sometimes, they also have a seconds hand.
- The hour hand is short and tells us what hour it is now. - The minute hand is long and tells us how many minutes ahead is the hour.

Digital watches
Digital clocks display the time with numbers. They usually separate the hours and minutes with a colon. For example,
3:00
It is three o'clock.
Am and pm
The 24 hours of a day are divided into two parts: AM (midnight to noon) and PM (noon to midnight).
- AM stands for "Ante Meridiem", which means "before noon." - PM stands for "Post Meridiem", which means "after noon."
Time-telling activities
Here are some activities to help students practice telling time:
Before and after
Practice determining what will happen before and after a certain time. For example, if it is 3:00 pm now, what time will it be an hour later? Or what time was it an hour ago?
If now: 3:00 PM, One hour later: 4:00 PM One hour ago: 2:00 PM
Matching time
Ask students to match the time on digital and analog clocks. They can draw hands on a blank clock face or write down the time displayed on the digital clock.
Daily schedule chart
Create a daily schedule for the student that highlights different activities at different times of the day. This helps to connect the concept of time with real-life activities.

Understanding the concept of time
To fully understand the concepts, students need to experience different ways of using and visualizing time.
Adding and subtracting time
Students can learn to add and subtract hours to figure out how much time has passed or how much time is left.
Start Time: 2:00 PM Add 3 hours: 2:00 + 3:00 = 5:00 PM Start Time: 6:00 PM Subtract 2 hours: 6:00 - 2:00 = 4:00 PM
Understanding the concept of "half an hour"
Half an hour means 30 minutes. This is the point in the clock when the minute hand moves halfway through the clock.
Start time: 3:00 PM After half an hour it will be 3:30
Quarter hour
A quarter of an hour is 15 minutes. Students can learn to identify times such as quarter past and quarter to.
Quarter to four: 4:15 5 minutes past 4: 4:45
Practical applications of time
Understanding time helps us in many ways. Here are some practical applications:
Time management
Knowledge of time helps students manage their daily tasks efficiently. Having a clear schedule helps ensure that tasks are completed on time.
To be on time
Understanding time helps everyone be punctual. This means arriving on time, whether it's for class, a meeting, or a fun activity.
Time-based activities
Many activities depend on time, such as watching a movie, playing a game with a timer, or cooking a meal using a recipe.
Conclusion
Time is a fundamental concept that students can learn through practical examples and engaging activities. By learning how to read clocks, know units of time, and manage their schedules, students become more efficient and confident in their daily routines. This comprehensive understanding of time is not only helpful in an academic setting but also promotes better life skills.
