8th grade Mathematics is a bridge between Upper primary and High school. Mathematics is treated differently from other subjects from the 6th grade onwards. It involves a deeper understanding of the concept, which can be mastered only through problem-solving from different perspectives. You can score high marks only if you spend quality time on yourself on difficult problems over and above the textbook standard.

If you have missed this and struggled in Mathematics through 7th grade, 8th grade is the right time to get back into the mathematics train. 8th grade takes Arithmetic and Algebra to a new level and consolidates Geometry, Mensuration, and Statistics to be treated at a higher level in the upcoming two grades.

• Arithmetic introduces two more operators, exponentiation and extraction, after discussing the set of Rational numbers through chapters on Squares and square roots, Cubes and cube Roots, and Exponents and powers.

• Algebra is dealt with in good detail for the first time through defining a general Algebraic expression and factorising it. Through the chapters, Algebraic Expressions and Factorisation, you learn to add, subtract, and divide Algebraic expressions. The course also introduces solving a linear equation in one variable through the method put forward by Al-Khwarizmi, the art of balancing & transposing.

• Geometry starts with properties of general polygons, to convex polygons, and discusses properties of quadrilaterals, or four-sided convex polygons, in detail. Here properties of parallelograms & different types of parallelograms will be a foundation for a student to master the art of problem solving in Geometry to come in 9th grade.

• Mensuration considers both 2D figures and 3D shapes. Under 2D figures, the chapter sticks to polygons and quadrilaterals discussed in Geometry. Under 3D figures, the chapter discusses how one can calculate the Surface Area & Volumes of cuboids, cylinders, & Cones.

• Statistics & Probability is considered together under two chapters: Data Handling & Introduction to Graphs, even an introduction to Coordinate Geometry is given under Introduction to Graphs. Through these chapters, you are given an introduction to the purpose of Data analysis. Starting from Data collection to Data representation and some basic analysis. Data Handling has a section on the purpose and basic definition of probability and an exercise to cement the general definition of probability when outcomes are equally likely and random.

• Now, finally, we have two chapters based on the application of arithmetic, which helps to compare quantities in our daily life and even subjects like Physics in High school. Starting with comparing quantities, which introduces ratios and percentages, and further moving on to the second chapter, which deals with ratios of two quantities that are in direct or indirect variation.
