Quick Summary

The chapter 'What is Long? What is Round?' introduces basic concepts of shapes and dimensions to children. Through interactive activities, children learn to identify objects that are long or round in their environment. The chapter involves classroom activities that engage children in identifying shapes and discussing their observations, fostering an understanding of geometric concepts. Additionally, a story about a lamb cleverly avoiding a wolf introduces the concept of rolling through the use of a cylindrical drum.

Key Topics

  • Understanding long and round objects
  • Recognizing shapes in everyday objects
  • Differentiating between rolling and sliding
  • Engaging children in interactive shape activities
  • Story-based learning about shapes
  • Comparing shapes by similarity

Additional Practice Questions

What makes certain objects roll more easily than others?

medium

Answer: Objects with a curved, circular surface like a ball or a cylindrical drum roll more easily due to reduced friction at the point of contact with the surface.

Why do flat objects tend to slide rather than roll?

medium

Answer: Flat objects have a large surface area in contact with the ground, increasing friction which prevents rolling but allows sliding.

Can an object both roll and slide? Give an example.

hard

Answer: Yes, objects like cylinders can both roll and slide. For instance, a bottle can roll when tilted and slide when pushed on its side.

What features of a carrom striker enable it to slide effectively?

easy

Answer: A carrom striker is smooth, reducing friction, and has a flat surface which aids in sliding across the board.

How does the story of the lamb relate to the concept of rolling?

easy

Answer: The lamb uses a cylindrical dholak to roll down and escape from the wolf, illustrating how cylindrical shapes can roll effectively on an inclined surface.
