Note for Teacher: Help children understand the difference between AM and 
PM and how it eases communication about time among people. You may seek 
children’s routine experiences and associate them with AM and PM. You may draw 
their attention to the 24-hour clock and how it shows time and make children 
practice reading and writing it.
In both the pictures we see 8:00 on the clock. But one is morning and 
the other is night time. We add AM and PM to show this difference.  
Digital clocks help us read the time more clearly.
Read the following table and see how we read and write time using 
AM/PM and the digital clock. Discuss what you notice about the two 
different ways.

FAQs on Class 4 Maths NCERT Book Chapter 12 Ticking Clocks and Turning Calendar

1. What is the importance of learning about clocks and calendars in Class 4?
Ans. Learning about clocks and calendars is important because it helps students understand time management and the concept of time in their daily lives. It also lays the foundation for mathematical skills related to measuring time and understanding dates, which are crucial for planning and organizing activities.
2. How do clocks work, and what are the different types of clocks mentioned in the chapter?
Ans. Clocks work by measuring time using a system of hours, minutes, and seconds. In the chapter, different types of clocks are mentioned, such as analog clocks, which have hands that move around a dial, and digital clocks, which display time in numerical form. Understanding these types helps students recognize how time is represented in various formats.
3. What are the key features of a calendar, and how is it used in everyday life?
Ans. A calendar features days, weeks, and months, and it is used to keep track of dates and events throughout the year. It helps people organize their schedules, plan for holidays, and remember important occasions like birthdays and anniversaries. The chapter emphasizes the significance of calendars in daily living.
4. How do we calculate time intervals using clocks and calendars?
Ans. We calculate time intervals by subtracting the earlier time from the later time on a clock or by counting the number of days, weeks, or months between two dates on a calendar. This helps in understanding durations, such as how long it takes to complete a task or how many days are left until an event.
5. Why is it essential for children to learn to read both analog and digital clocks?
Ans. It is essential for children to learn to read both analog and digital clocks because it enhances their ability to tell time in different contexts. While digital clocks are commonly used in technology, analog clocks are still found in many places. Being proficient in both formats prepares children for various situations they may encounter as they grow older.
