Beginner12 pages • EnglishQuick Summary
In the chapter 'Rani’s Gift' from Class 2 Math, the story revolves around Raja Jagdeep who wants to build a splendid carved bed for his queen. However, there's confusion about measuring the bed's length. The chapter then transitions into activities that help students understand measurements through exercises like choosing paths, comparing weights, and measuring objects using non-standard units. It encourages practical involvement through activities like making a balance and projects that require measuring and comparing weights or quantities.
Key Topics
- •Measurement using hand spans
- •Comparing weights of objects
- •Standard vs non-standard units
- •Using thread for measuring distances
- •Project work with everyday objects
- •Creative activities for hands-on learning

Additional Practice Questions
If a carrot weighs 2 units, and a pumpkin weighs 8 units, how many carrots equal the weight of one pumpkin?
easyAnswer: One pumpkin weighs the same as 4 carrots, since 8 units (pumpkin weight) divided by 2 units (carrot weight) equals 4.
Create a story problem involving objects of different weights and how to balance them using a see-saw. Provide a numerical answer.
mediumAnswer: Use known weights like 3 units for a small toy and 6 units for a medium toy. If you put the medium toy on one side of the see-saw, how many small toys are needed to balance it? 2 small toys are needed because 2 * 3 units = 6 units.
Discuss what happens if the bed is measured in different hand sizes and why this could cause confusion.
mediumAnswer: Different people may have different hand sizes, leading to different measurements for the same object. This inconsistency can cause misunderstandings when exact measurements are needed.
Find three items at home to create your own weighing scale. Explain how to use it to compare two objects.
hardAnswer: Use a hanger, two paper cups, and some string. Attach the cups to each side of the hanger. Hang the setup and place different items in each cup to see which is heavier based on the tilt of the hanger.
Why is it important to use standard units of measurement in real life? Provide examples and explanations.
hardAnswer: Standard units, such as meters and kilograms, ensure consistency and reliability in measurements. For instance, when building a house, precise measurements prevent mistakes in construction. Using liters ensures that products like drinks have consistent volume.
