SHAPES AND
PATTERNS

Shapes help us understand
the world around us.
Everything we see has a
shape—whether it's a ball, a
book, or a pizza!
Shapes are the outlines or
boundaries of objects.
They can be made using
curves, points, and line
segments.
Some shapes have straight
edges, while others are
round.

Types of Shapes
Open Shapes
Some shapes have gaps and do not
have a closed boundary. These are
called open shapes.
Closed Shapes
These shapes have a complete
boundary with no gaps. A closed
shape starts and ends at the same
point.
Examples: Letter C, Letter U, a
curved line.
Examples: Letter O, Letter B, a
square.

Common Shapes and Their Properties:
Circle
A circle is a round shape that has no
corners or straight lines.
It is a two-dimensional (2D) shape.
No edges, no corners.
Examples: Steering wheel, Pizza,
Dartboard.
Oval
An oval looks like a stretched circle.
It has no straight lines or corners.
Example: Number 0 (zero), An egg,
A balloon.

Square
A square is a shape with four equal
sides.
All four sides are of the same length.
It has four corners and four edges.
Examples: Chessboard, Carrom
board, Window pane
Rectangle
A rectangle looks like a square but has
two longer and two shorter sides.
Opposite sides are equal in length.
It has four corners and four edges.
Examples: Laptop screen, Mobile
phone screen, Door
