Class 4 Maths - CBSE
Shapes Around Us
In the Class 4 CBSE chapter 'Shapes Around Us', students explore basic geometric shapes like rectangles, squares, triangles, and circles that we see in everyday life. The chapter introduces fundamental concepts of 2D and 3D shapes, identifying their sides, corners, and faces. Understanding these shapes helps young learners recognize spatial patterns and symmetry, which form the building blocks of advanced geometry in later board exams. This chapter is vital for developing observational skills and spatial awareness, frequently appearing in CBSE examinations through figure identification and property-based questions.

Plane Shapes (2D Shapes)
Flat shapes that have only two dimensions, length and width, such as squares, rectangles, triangles, and circles.
Sides and Corners
Sides are the straight lines that make up a shape, and corners (or vertices) are the points where two sides meet.
Solid Shapes (3D Shapes)
Objects that take up space and have three dimensions: length, breadth, and height, like cubes, cylinders, and spheres.
Faces, Edges, and Vertices
Faces are the flat surfaces of a solid shape, edges are where two faces meet, and vertices are the corners.
Tiling (Tessellation)
The pattern of fitting shapes together without any gaps or overlaps, commonly seen in floor tiles.

Board Exam Info
In CBSE Class 4 Mathematics, this chapter typically carries around 5 to 8 marks. Common question types include matching shapes with their properties, counting the number of sides and corners in a given figure, identifying 2D shapes hidden within 3D objects, and completing simple tiling patterns.
Frequently Asked Questions
Does a circle have any corners?
No, a circle is a curved shape and has zero corners and zero straight sides.
What is the difference between a square and a rectangle?
A square has 4 equal sides, while a rectangle has only its opposite sides equal to each other.
How many faces does a cube have?
A cube has 6 flat faces, and all of its faces are identical squares.
