Question I. Write the shape of these objects.
(a) A bangle ________________
(b) The page of a book ___________________
(c) A birthday cap __________________
(d) A foot ball _____________________
(e) A shoe box__________________
Answer:
(a) Circle
(b) Rectangle
(c) Cone
(d) Sphere
(e) Cuboid
In simple words: All things around us have a shape. A bangle is round like a ring. A book page is flat with four corners. A party hat has a pointed top. A football is round like a big bubble. A shoe box is a solid box with flat sides.

Exam Tip: Learn the difference between flat 2D shapes like a circle and solid 3D shapes like a sphere.

Question II. Which of these has the maximum number of vertices?
(a) Square (b) Triangle (c) Circle
Answer: (a) Square
In simple words: A vertex is a corner. A square has 4 corners, a triangle has 3 corners, and a circle has no corners at all. So, the square has the most corners.

Exam Tip: Remember that "vertex" is just the math word for a corner where straight lines meet.

Question III. Look for the pattern and complete the series for each of the following:
(a)
(b)
(C)
Answer:
(a)

(b)

(C)

In simple words: Look closely at the shapes to see how they repeat. Then draw the next shapes in the same order to continue the pattern.

Exam Tip: First find the repeating group of shapes, and then copy them to fill the empty spaces correctly.
