Class 8th Mathematics
Rational Numbers
Rational Numbers : The numbers which are involved in many mathematical applications such as addition, subtraction and multiplication
Linear Equations in One Variable
Linear Equations in One Variable : An equation is a statement of equality of two algebraic expressions involving one or more unknown quantities.
Understanding Quadrilaterals
Understanding Quadrilaterals : A plane figure formed by joining a number of points without lifting a pencil from the paper.
Practical Geometry
Practical Geometry : A quadrilateral has four sides, four angles and two diagonals, i.e., 10 elements. A quadrilateral can be constructed uniquely
Data Handling
Data Handling : A collection of information is called the data. Data obtained in the original form is called a raw data.
Squares and Square Roots
Squares and Square Roots : Square of a number is obtained when it is multiplied by itself twice. Thus, square of x = (x × x), denoted by x2.
Cubes and Cube Roots
Cubes and Cube Roots : If a natural number m can be expressed as n3, where n is also a natural number, then m is called the cube number of n
Comparing Quantities
Comparing Quantities : A fraction represents a part of a whole which consists of numerators and denominators and it is the division of two same quantities.
Algebraic Expressions and Identities
Algebraic Expressions and Identities : Algebraic expressions are expressions made up of variables and constants along with mathematical operators.

Visualising Solid Shapes
Visualising Solid Shapes : A shape with only two dimensions (such as length and width) and no thickness is called two-dimensional shape.
Mensuration
Mensuration : Area of a general quadrilateral can be found by dividing it into two triangles, by drawing on of its diagonals.
Exponents And Powers
Exponents And Powers : As the exponent increases by 1 the value becomes ten times the previous value. Large numbers can be written in shorter.
Direct and Inverse Proportions
Direct and Inverse Proportions : If two quantities are related such that a change in one causes a corresponding change in the other.
Factorisation
Factorisation : When an algebraic expression is written as the product of two or more expressions, then each of these expressions
Introduction to Graphs
Introduction to Graphs : Graphical methods used to present data is very efficient in organizing the data and understand them.
Playing with Numbers
Playing with Numbers : When a two digit number is reversed and added with the number, the resulting number is perfectly divisible by 11
