1. Introduction to Symmetry: Symmetry refers to a figure or object where parts are repeated in a definite pattern. Examples include butterflies, flowers, pinwheels, and rangoli designs. Objects without a repetitive pattern, like clouds, are not symmetrical. 2. Line of Symmetry: A line of symmetry divides a figure into two parts that perfectly overlap when […]
Playing with Constructions Basic Figures & Tools: Ruler and Compass: Tools used to draw accurate geometric shapes. Curves: Includes straight lines, circles, etc. Using a compass, you can draw precise curves and circles.

Understanding Fractions: A fraction represents how much each person gets when a whole number of items is shared equally. Example: If one roti is divided among two children, each gets half a roti, written as Fractional Units and Equal Shares: When a whole unit is divided into equal parts, each part is a fractional unit. […]
Perimeter The perimeter of a closed figure is the total length of its boundary. For polygons (figures made of straight lines), the perimeter is the sum of the lengths of all sides. Formulas: Perimeter of a rectangle: P = 2 × (length + breadth) Perimeter of a square: P = 4 × side Perimeter of […]
