Class 4 Maths - PUNJAB
Shapes Around Us
The chapter Shapes Around Us in Class 4 Mathematics introduces young learners to the basic geometric shapes that make up our daily environment. Students learn to identify, describe, and differentiate between 2D shapes like squares, rectangles, triangles, and circles, as well as 3D shapes like cubes, cuboids, cylinders, cones, and spheres. They explore fundamental properties such as sides, corners, and faces. This chapter is vital for the Punjab (PSEB) board exams as it builds the essential foundation for advanced geometry, spatial understanding, and drawing skills tested in both objective and descriptive question formats.

Plane Shapes (2D Shapes)
Flat shapes that have only two dimensions, length and breadth, and can be drawn on a flat surface like paper.
Solid Shapes (3D Shapes)
Objects that take up space and have three dimensions: length, breadth, and height or thickness.
Sides and Corners
A side is a straight line that makes the boundary of a shape, and a corner (vertex) is where two sides meet.
Faces, Edges, and Vertices
Faces are the flat or curved surfaces of a 3D shape, edges are where two faces meet, and vertices are the corners.
Symmetry
A shape has symmetry if it can be divided into two identical halves that match up completely when folded.

Board Exam Info
In the Punjab (PSEB) Class 4 Mathematics exams, this chapter typically carries around 6 to 8 marks. Common question types include matching shapes with their real-life objects, counting the number of sides and corners in 2D figures, identifying faces and edges of 3D objects, and completing simple pattern-based drawing questions.
Frequently Asked Questions
What is the difference between a square and a rectangle?
A square has 4 sides of equal length, whereas a rectangle has 4 sides where only the opposite sides are equal in length.
Does a circle have any corners?
No, a circle has a curved boundary and zero corners or straight sides.
How many faces does a brick or a cuboid have?
A cuboid has 6 flat faces, 12 edges, and 8 corners.
