Introduction to CBSE Class 4 Mathematics Chapter "How Heavy, How Light"
In “How Heavy, How Light,” CBSE Class 4 students learn to understand and work with the concept of weight. The chapter introduces different units of weight, such as kilograms and grams, and guides students on how to measure and compare the weight of different objects. Practical activities help students estimate weights in real-life situations and comprehend the conversion between units.
The chapter also delves into the use of balance scales and the idea of ‘heavier’ and ‘lighter’ as comparative terms. Through a variety of exercises, students practice measuring weight using traditional and modern methods, thus gaining an appreciation for accuracy in measurement. By comparing and ordering objects based on weight, students enhance their analytical skills and begin to understand the practical implications of mathematics in everyday life.
Assignments for CBSE Class 4 Mathematics Chapter “How Heavy, How Light”
- Weight Estimation Exercise: Estimate the weight of everyday objects at home, like a bag of rice, a water bottle, and then check your estimates using a weighing scale.
- Conversion Chart: Create a conversion chart that helps convert grams to kilograms and vice versa.
- Scavenger Hunt: Find items around the house or classroom that weigh approximately 1 kilogram, 500 grams, 250 grams, and so on.
- Heaviest to Lightest: List 5 objects at home or in the classroom and arrange them in order from heaviest to lightest based on estimation.
- Real-World Math: Visit a grocery store and observe the weighing process. Note down the weights of different items bought and compare them at home.
Conclusion The “How Heavy, How Light” chapter is crucial for instilling a clear understanding of weight and its measurement in CBSE Class 4 students. These concepts form the foundation for future mathematical and scientific studies. This chapter not only enhances their numerical skills but also prepares students to apply these concepts in real-life scenarios, promoting practical learning and problem-solving.

Questions and Answers for CBSE Class 4 Mathematics Chapter "How Heavy, How Light"
- Q1: What are the two main units of weight discussed in this chapter? ANS: The two main units of weight discussed in this chapter are kilograms (kg) and grams (g).
- Q2: How many grams are there in one kilogram? ANS: There are 1000 grams in one kilogram.
- Q3: When do we use the term ‘heavier’? ANS: We use the term ‘heavier’ when comparing two objects, and one weighs more than the other.
- Q4: What is a balance scale? ANS: A balance scale is a device used for measuring the weight of objects by comparing them with a set of standard weights.
- Q5: Why is it important to know how to estimate weight? ANS: Knowing how to estimate weight is important for making quick decisions, verifying the correctness of measured weight, and for everyday tasks like cooking and shopping.
- Q6: How can you check if your estimation of weight is accurate? ANS: You can check if your estimation is accurate by using a weighing scale to measure the actual weight of the object.
- Q7: What is a kilogram used to measure? ANS: A kilogram is used to measure heavier weights, like the weight of a bag of rice or a person.
- Q8: Can the weight of an object change? ANS: The weight of an object does not change unless material is added to or removed from the object; however, the apparent weight can change due to gravity variations if measured in different places.
- Q9: Is a gram a larger unit than a kilogram? ANS: No, a gram is a smaller unit than a kilogram. One kilogram is equal to 1000 grams.
- Q10: What practical activities can help understand weight better? ANS: Practical activities like using a weighing scale, estimating and verifying the weight of common items, and converting units can help understand weight better.
