Review the key concepts, formulae, and examples before starting your quiz.
🔑Concepts
Understanding Duration: Activities take different amounts of time to complete. Some take seconds (like blinking or snapping fingers), some take minutes (like brushing teeth or eating an apple), and some take hours (like watching a movie or sleeping). Imagine a 'Time Scale' where a second is a tiny dot and a year is a very long line.
The Sequence of Events: This means arranging activities in the order they happen from first to last. We use words like 'before', 'after', 'first', 'then', and 'finally'. Visualise a staircase where the bottom step is the start of your day and the top step is the end of your day.
Clock Basics: A clock face is a circle numbered from to . It has two main hands: a short 'Hour Hand' and a long 'Minute Hand'. When the minute hand points to , the hour hand tells us the exact hour. For example, if the short hand is at and the long hand is at , the time is or o'clock.
Units of Time: Time is measured in different units that fit into each other. seconds make minute, and minutes make hour. Think of these like nested boxes where the small 'seconds' box fits into the 'minutes' box, which fits into the 'hours' box.
The Calendar: A calendar shows the days of the week and the months of the year. There are days in a week and months in a year. Visualise a calendar as a large grid where each row represents one week and each box represents one day.
AM and PM: A full day has hours, divided into two -hour periods. 'AM' (Ante Meridiem) is the time from midnight until just before noon (morning). 'PM' (Post Meridiem) is the time from noon until just before midnight (afternoon and night). Imagine a sun icon for AM and a moon icon for PM.
Seasons and Years: A year is the time it takes for the Earth to go around the Sun once, usually days. Within a year, we experience different seasons like Summer, Winter, and Monsoon. Picture a cycle or a wheel that repeats every months.
📐Formulae
💡Examples
Problem 1:
Arrange the following activities in the correct sequence from morning to night: 1. Doing Homework, 2. Eating Breakfast, 3. Sleeping, 4. Coming back from school.
Solution:
- Eating Breakfast (Morning) \ 2. Coming back from school (Afternoon) \ 3. Doing Homework (Evening) \ 4. Sleeping (Night)
Explanation:
To sequence events, we look at the natural order of a daily routine. Breakfast happens first after waking up, school ends in the afternoon, homework is usually done after school, and sleeping is the final activity of the day.
Problem 2:
Ravi started playing football at PM. He played for hour and minutes. At what time did he finish playing?
Solution:
Explanation:
To find the finish time, we add the duration to the start time. First, add the full hours, then add the remaining minutes to the result.
