Key concepts
A clock helps us to know the time. It has numbers from 1 to 12. It has two main hands:\n* The **short hand** is called the **hour hand**. It tells us the hour.\n* The **long hand** is called the **minute hand**. When the minute hand points to 12, it means 'o'clock'.
Money is called currency. In India, our currency is the **Indian Rupee (₹)**. We use coins and notes.\n* **Coins**: We have coins of ₹1, ₹2, ₹5, and ₹10.\n* **Notes**: We have notes of ₹5, ₹10, ₹20, ₹50, ₹100, and more.\n* We also have **Paise**. 1 Rupee is equal to 100 Paise, but for Class 2, we mostly focus on Rupees.
A pictograph is a way to show information using pictures. Each picture stands for a certain number of things. A **key** tells us what each picture means. It makes data easy to understand.
Key facts to remember
- 1A clock has 12 numbers and two main hands: the hour hand (short) and the minute hand (long).
- 2When the minute hand points to 12, the time is 'o'clock'.
- 3The Indian currency is the Rupee (₹).
- 4We use coins (₹1, ₹2, ₹5, ₹10) and notes (₹5, ₹10, ₹20, ₹50, etc.).
- 51 Rupee = 100 Paise.
- 6A pictograph uses pictures to show information or data.
- 7The 'key' in a pictograph tells us what each picture represents.
Worked examples
Example 1
What time does the clock show? (Imagine a clock with the hour hand pointing at 4 and the minute hand pointing at 12).
Answer
The time is 4 o'clock.
Example 2
How much money is there in total? (Imagine one ₹10 note, one ₹5 coin, one ₹2 coin, and one ₹1 coin).
Answer
There is ₹18 in total.
Always count carefully, one by one, to avoid mistakes.
Example 3
The pictograph below shows the number of different coloured balloons a shopkeeper has.\nRed Balloons: 🎈🎈🎈🎈🎈\nBlue Balloons: 🎈🎈🎈\nGreen Balloons: 🎈🎈\nKey: Each 🎈 = 1 balloon.\nQuestion: How many red balloons does the shopkeeper have?
Answer
The shopkeeper has 5 red balloons.
Common mistakes
- ✗Confusing the hour hand (short) with the minute hand (long) when reading time.
- ✗Incorrectly adding up the value of different coins and notes.
- ✗Forgetting to look at the 'key' in a pictograph, leading to wrong answers.
- ✗Not understanding that one picture in a pictograph can represent more than one item (though for Class 2, it's often 1:1).
Exam tips
- ★When reading a clock, always identify the hour hand first, then the minute hand.
- ★Count money systematically, starting from the largest denomination to the smallest, or one by one.
- ★Always read the 'key' of a pictograph carefully before answering any questions.
- ★Practice drawing simple pictographs to understand how data is represented.
