Class 8 is one of the most crucial time of studentâ€™s academic life. One basically starts to sift through their interests and focus on the subjects of their choice. This is also a time to build a strong base in the subjects that you are studying and gear up for the next two years which would eventually culminate in the final board exams. So, just like every other subject, the class 8 maths syllabus is also structured with great care and with the right details so that students can strengthen their base in the maths topics that will come handy for the rest of their lives.
What does the class 8 maths syllabus include?
There is quite a long list of topics that have to be covered by class 8 students when it comes to mathematics. Rigorous practise and proper detailed introduction to the concepts will always help. Let us take a look at the most important topics that are covered during this grade cubes and cube roots, squares roots and squares, rational numbers, powers and exponents, linear equations with one variable, comparing quantities, understanding direct and inverse proportions, identities and important algebraic equations, understanding and introduction to quadrilaterals, basic introductory concepts of graphs, practical usage of geometry, number problems, solid shapes and their visualization, important topics of mensuration and data handling.
There are various subtopics under these headings that the class 8 maths syllabus covers, some in great detail while some in their introductory form, in keeping with the students of grade 8 level. Well if you are looking for a better understanding of the class 8 mathematics syllabus, then here is a more detailed list of all the topics and their basic concepts:
Rational Numbers 

 Basic introduction to rational numbers and its properties. The numbers which can be represented the format of p/q where both the numbers are integers, where q cannot be equal to zero is known as a rational number.

 Various properties of rational numbers that will be touched upon closure property, commutative law and associative law.

 A basic understanding of the number line and how the rational numbers can be represented on them with the help of diagrammatic representation.
 The process of finding out rational numbers between two given rational numbers. The simple way to do that would be to add the two given numbers and divide them by 2. A few other methods will be elaborated upon as well.

Cube roots and cubes 

 Understanding what a cube is. A figure which is three dimensional in visualization and has sides which are of equal length defines a cube. If one is to calculate the volume of the cube, one has to simply multiply the length of the side by itself, three times. Examples of perfect cubes will be provided.
 The cube root is the inverse of the cube number. Basic methods and problems dealing with finding the cube root of a number will be touched upon in the class 8 maths syllabus.

Powers and exponents 

 How to express integers in their exponential forms.
 Understanding of the various exponent laws when they come with integral powers.

Linear equations with one variable

 Basic understanding of the concept of a linear equation
 What does it mean when a linear equation has only one variable
 Various methods of solving linear equations which have only one variable.

Square roots and squares

 Understanding what the square of a number is. One can find the square of a number by multiplying it by itself twice.
 Ways to find the square root of a number through the method of repeated subtraction
 Use of the prime factorization method to find out the square root of a given number
 Use of the long division method to find out the square root of a given number
 How to find the square root of a decimal
 How to find the estimation of a square root will also be touched upon in the class 8 maths syllabus

Comparison of quantities

 A brief revision of the concepts of percentage and ratio and the various ways through which the decrease or increase of a percentage can be found
 The methods through which one can find discount and various calculation of taxes
 Introduction to compound interest and its formula
 Solving

Inverse and direct proportions

 Basic introduction to the two concepts and some examples and solutions

Introduction to Factorization

 Understanding what factorization means
 Understanding the method of factorization and its application
 Use of identities in Factorization
 Use of factorization in case of algebraic expressions

Introduction to Quadrilaterals

 Understanding the concept of polygons and measuring the sum of the exterior angles of a polygon
 The different types of quadrilaterals
 Understanding what a parallelogram is its properties and some special ones

Identities and algebraic expressions

 Introduction to expressions and their subtraction and addition in lieu of the class 8 maths syllabus
 Monomials and polynomials and their multiplication
 Understanding standard identities

Graphs

 Introduction to the concepts of a pie graph, bar graph and a line graph
 Understanding linear graphs and their various applications

Number problems

 Reversing number digits
 Substitution of numbers by letters
 Divisibility tests for the numbers 2,3, 5, 9 and 10

Introduction to solid shapes

 Understanding how 3D shapes are viewed
 Understanding the concept of vertices, edges and faces
 How can we map the shapes that we see around us

Data Handling

 How to find data, organize it and group it
 Understanding pie charts and circle graphs
 Introduction to the concepts of probability and chance

Apart from these various aspects of mensuration of the class 8 maths syllabus will include areas of a trapezium, a general quadrilateral, polygon and finding the surface area of cuboid, cubes, cylinders and calculation of their volumes and capacity will also be covered. The Geometry section will cover in greater detail the concepts of the construction of quadrilaterals with provided different sets of data.
