3 📖 Explain

A clock has a short hand for hours and a long hand for minutes. When the long hand points to 12, it is "o'clock"; at 6 it is "half past"; at 3 it is "quarter past"; at 9 it is "quarter to".

There are 60 minutes in an hour and 24 hours in a day. Morning times are a.m. and afternoon and evening times are p.m.

A calendar shows days, weeks and months. A week has 7 days and a year has 12 months. Find a date in its box and look at the top of the column for the day.

🇮🇳 Example from India

The milk comes at 6:30 in the morning, school starts at 8:30 and the evening bus leaves at 5:00. Festivals like Sankranti and Diwali are marked on the calendar.

⚠️ Common mistake

✗ At 4:30 the short hand points exactly at 4.
✓ At 4:30 the short hand is halfway between 4 and 5, because half the hour has passed.

5 🏡 Real-life task

Try this at home or at school, then check the suggested answer.

Scenario Your cricket match starts at quarter past four and lasts one hour. What time does it end?

Draw a clock for 4 times in your day (wake up, school, play, sleep). On a calendar, find your birthday and say which day it falls on this year.

6 💭 Reflect

Think, then answer in your own words. Your notes stay on this device.

Observation In the 3D scene, look at both hands at half past. What do you notice about the short hand?

Show a suggested answer

The short hand is halfway between two numbers, because half an hour has passed since the hour.

Explain / create Make a daily timetable for a friend with times shown as clocks, and ask them to read one.

Show a suggested answer

For example: wake up 6:00, school 8:30, lunch 12:30, play 5:00. The friend reads the long hand for minutes and the short hand for the hour.
