Class 4 Maths - TELANGANA
Shapes Around Us
In the Class 4 Mathematics chapter 'Shapes Around Us', Telangana students explore basic 2D and 3D shapes like circles, rectangles, squares, triangles, cones, cylinders, spheres, and cuboids. This chapter helps children identify geometric patterns in everyday objects around them, laying the foundation for spatial understanding and advanced geometry. Students learn to count sides, corners, and faces of different figures. This chapter is vital for the Telangana (TSBSE) board exams as it builds core observational skills, tests basic definitions through objective questions, and carries steady weightage in formative and summative assessments.

2D Shapes (Two-Dimensional Shapes)
Flat shapes that have only length and width, such as squares, rectangles, triangles, and circles.
3D Shapes (Three-Dimensional Shapes)
Solid objects that have length, width, and height, such as cubes, cuboids, cylinders, cones, and spheres.
Sides and Corners
A side is a straight line that makes up the boundary of a 2D shape, and a corner (or vertex) is where two sides meet.
Faces, Edges, and Vertices
In 3D shapes, a face is a flat surface, an edge is where two faces meet, and a vertex is a corner point.
Rolling and Sliding
Round objects like spheres and cylinders roll on a surface, while flat-faced objects like cubes and cuboids slide.

Board Exam Info
In the Telangana (TSBSE) Class 4 mathematics examinations, this chapter typically carries about 5 to 8 marks. Common question types include matching shapes to real-life objects, identifying the number of sides and corners in 2D shapes, counting faces and edges of 3D objects, and short-answer questions classifying items that roll or slide.
Frequently Asked Questions
What is the difference between a 2D shape and a 3D shape?
2D shapes are flat and have only two measurements (length and width), whereas 3D shapes are solid and have three measurements (length, width, and height).
How many corners does a circle have?
A circle has zero corners and zero straight sides because its boundary is a continuous curved line.
Why do some objects roll while others slide?
Objects with curved surfaces like spheres and cylinders can roll easily, while objects with flat surfaces like cubes and cuboids slide.
