Class 4 Maths - ODISHA
Shapes Around Us
The chapter 'Shapes Around Us' in Class 4 Mathematics for Odisha (BSE) introduces students to fundamental geometric figures found in their daily environment. Students learn to identify, name, and differentiate between basic 2D shapes like rectangles, squares, triangles, and circles, as well as 3D shapes like cubes, cuboids, cylinders, cones, and spheres. The chapter also explores properties such as sides, corners (vertices), and faces. This forms the essential building block for advanced geometry in later board exams, making observational skills and shape recognition crucial for scoring good marks in both formative and summative assessments.

Line Segment
A straight path between two points that has a fixed length and can be measured using a ruler.
Plane Shapes (2D Shapes)
Flat shapes that have only two dimensions, length and breadth, such as squares, rectangles, triangles, and circles.
Solid Shapes (3D Shapes)
Objects that have three dimensions—length, breadth, and height—and occupy space, like cubes, cylinders, and spheres.
Vertices and Sides
A side is a straight line that makes up a shape, and a vertex (corner) is where two sides meet.
Faces, Edges, and Corners
Solid shapes have flat or curved surfaces called faces, lines where faces meet called edges, and points where edges meet called corners.

Common question types include matching shapes to their real-life objects, counting the number of sides and corners in given 2D shapes, filling in the blanks regarding properties of 3D shapes, and drawing simple geometric figures.
Frequently Asked Questions
Does a circle have any corners?
No, a circle is completely round and has no straight sides and no corners.
What is the difference between a square and a rectangle?
A square has all 4 sides of equal length, while a rectangle only has its opposite sides equal.
How many faces does a brick or a cuboid have?
A cuboid has 6 flat faces, 12 edges, and 8 corners.
