Shapes around us


All solid shapes we see around us are combinations of a few simple shapes. These idealised shapes are Sphere, Cylinder, Cone, Cuboid and Cube ( cube is a special case of a cuboid).

For example, the human body can be considered as a combination of Cylinders and Spheres. Similarly, hills look like cones, tree trunks and containers are like cylinders and houses can be made of cubes and cones.

Shapes are made of three kinds of things - Faces (called surfaces in geometry), Edges (lines) and Corners (points). Surfaces can be flat or curved. Lines can be straight or curved.


Recognise that all shapes are made up of simple shapes.

Count the number of surfaces, lines and points in simple shapes.


Pick up any object you see. Feel its surfaces using the palm of your hand. Feel its edges by tracing your finger on them. Feel its corners by pressing your finger on them. Corners can be sharp. Be careful.

Make a tabular column with the following heads - Name of the object; Number of faces; Number of edges; Number of corners.

Fill up the tabular column. Compare different objects.
