14 Chapters

Class 6
CBSE

## Overview

Class 6 Maths will introduce students to different concepts of numbers, geometrical ideas, Algebra, and many more. It begins by teaching students about the universal arrangement of numbers, Roman numerals, and more. Further, Whole numbers will focus solely on whole numbers and natural numbers. After that, Playing with Numbers will dive deep into prime numbers, coprime numbers, HCF and LCM as well. Moreover, Basic Geometrical Ideas will focus on geometric shapes like rectangle, triangle, circles, and more. Next, Understanding Elementary Shapes as the name suggests is about edges, planes, corners, line segments, and more. The chapter of Integers will help students get all information about Integers and their addition and subtraction. Similarly, Fractions will teach students about the various types of fractions, and Decimals will deal in addition, subtraction of decimals as well as comparing decimals and more. The chapter of Data Handling is about various types of data and their recordings like bars, pictographs, and more. Further, Mensuration will discuss perimeter concepts and areas of simple geometric figures. Algebra will teach students about matchstick patterns, variables, and others. On the other hand, students will study about Ratio and Proportions and Symmetry and the symmetric figures. Finally, Practical Geometry will teach them to draw geometric shapes and measure them.

### Chapter 1 : Knowing Our Numbers

Did you know the Sumerians were the first people to develop their own number system? Numbers have been around for nearly 5000 years. And as time has passed we have made more advances in the field of mathematics. We also must develop our understanding beyond the basic functions. Let us get started!

### Chapter 2 : Whole Numbers

What are the whole numbers? And how are they different from the natural numbers? Is zero '0' are part of the whole number system? If we are counting anything, we start the count from 0. It makes the counting number system as 'whole'. Let's learn about how to represent them on a number line, their properties and types.

### Chapter 3 : Playing With Numbers

Can you imagine playing the games like snakes and ladder or rolling the dice without numbers? Definitely not! Numbers play a very important role in our day to day life. We have made more development in the field of mathematics. Let us start understanding these numbers by studying the topic playing with numbers.

### Chapter 4 : Basic Geometrical Ideas

Vidoe games are fun to play, especially because of depth, and movement in them. But how is this created? Well, the simple answer to this is 'geometry'. Geometry allows us in determining how the shapes and figures fit together to maximize efficiency. So, let us get acquainted with geometry basics ideas!

### Chapter 5 : Understanding Elementary Shapes

The first things that we tend to understand about objects that we see are colour and shape. In many instances, we understand the function of certain objects by seeing their shapes. Thus, it is important to understand elementary shapes. Let's study the topics in this section.

### Chapter 6 : Integers

Suppose you take a jar and add 5 chocolates into the jar. It is represented by a positive value +5. Now remove 5 chocolates from a jar so this is represented by a negative value -5.  But can you remove half of or a third of chocolate? NO!  So here the integer always represent the number of chocolates added or taken.

### Chapter 7 : Fractions

Number Series is a sequence formed out of numbers. In the number series questions, we will have to detect the rules that result in the formation of a number series. The number series are of many kinds. In this chapter, we have formulated all the types and kinds of the Number Series and the concepts that you will need.

### Chapter 8 : Decimals

Decimal Numbers are the numbers that have a decimal point in them. They have a whole part and a fractional part separated by the point. Decimal Numbers have applications in many fields. In real-life, it has its applications in money, food and lot more. Here, We will learn about Decimal Numbers and their uses.

### Chapter 9 : Data Handling

Your life is surrounded by numbers. Marks you scored, runs you made, your height, your weight. All these numbers are nothing but data. Here we will learn what is data and how to organise and represent this data in forms of graphs and charts. We will also come across the concept of probability. Let us get started.

### Chapter 10 : Mensuration

Suppose you want to put a boundary around your garden or field. For that, you need to find out the length of the boundary. Also, what if you want to find out the area and volume of different geometrical shapes. Let us study the topic mensuration and mensuration formulas in detail.

### Chapter 11 : Algebra

Imagine it's your best friend's birthday and he/she hosts a party which is at 7 PM. You suddenly get caught in traffic. Now, you know a shortcut to reach the venue faster but you can't move until the signal's clear. What do you do? We use algebra and algebraic expressions. But what are these terms? Let us study them.

### Chapter 12 : Ratio and Proportion

The ratio or the proportion of two quantities is an effective way to measure the relative magnitude of two quantities. The entire concept of ratio and proportion has been put in the form of simple words and solved examples in the below topics.
