Class 4 Maths - HARYANA
Shapes Around Us
In the Class 4 Mathematics chapter 'Shapes Around Us', students explore basic geometric shapes that we see in our everyday life, such as rectangles, squares, circles, triangles, and basic 3D objects. This chapter helps children understand the properties of these shapes, including counting sides, corners, and understanding straight and curved lines. It forms the foundational base for geometry in the Haryana Board (BSEH) curriculum. Mastering this chapter is essential for scoring well in board exams as it tests both visual observation and basic spatial reasoning skills through simple diagram-based and identification questions.

Point
A point is a tiny dot that gives us an exact position or location and has no length, width, or thickness.
Line and Line Segment
A line goes on endlessly in both directions, while a line segment is a straight path with a fixed starting point and a fixed ending point.
Plane Shapes (2D)
Flat shapes like squares, rectangles, triangles, and circles that have only two dimensions: length and breadth.
Solid Shapes (3D)
Objects that take up space, such as cubes, cuboids, cylinders, cones, and spheres, having length, breadth, and height.
Sides and Corners
Sides are the straight lines forming the boundary of a shape, and corners (or vertices) are the points where two sides meet.
