Knowing our numbers

Counting things is easy for us now. In this chapter we will learn more about large numbers and what we can call them!

Whole numbers

Natural numbers are the set of numbers ranging from 1 to infinity. If we add 0 to this set we get a new set of numbers called 'Whole numbers'.

Playing with numbers

In this chapter we will learn about factors and multiples and about the divisibility rules for 2, 3, 4, 5, 6, 8, 9 and 10

Basic geometrical ideas

Geometry comes from the greek words for "earth" and "measurement." It is the study of shapes and sizes. In this chapter, we will develop a strong foundation for geometry.

Understanding elementary shapes

Corners, edges, planes, open curves and closed curves are different shapes that we see around us. Understanding these shapes can help us solve a wise variety of real world problems.

Integers

The set of numbers from 1 to infinity is called Natural numbers. When we add 0 to this, we get whole numbers. A set of 0, natural numbers and their opposites, make up 'integers'.

Fractions

A fraction is a number representing part of a whole. We use fractions in everyday life, from dividing a pie to even checking the time. 3/4, 56/3, 25/4 etc. are all fractions.

Decimals

A dot represents a decimal point. In real life problems like measuring of length, weight, or time, the values are not exact whole numbers but rather portions of whole number. In situations where we need to be exact, we use decimal numbers.

Data handling

Data is a collection of numbers gathered to represent some information.

Mensuration

Mensuration is the branch of mathematics which deals with the study of Geometric shapes, their area, volume and related concepts.

Algebra

Algebra is the language through which we describe patterns in mathematics. It involves usage of letters with numbers to depict problems.

Ratio and proportion

In certain situations, comparison by division makes better sense than comparison by taking the difference. The comparison by division is called the ratio of the two numbers.

Symmetry

Symmetry is when one shape becomes exactly like another if you flip, slide or turn it.

Practical Geometry

Geometry is to draw various shapes with tools like rulers, compasses, dividers, set squares and protractors. It is the study of shapes.

Ratio and proportion

In certain situations, comparison by division makes better sense than comparison by taking the difference. The comparison by division is called the ratio of the two numbers.

Introduction

In certain situations, comparison by division makes better sense than comparison by taking the difference. The comparison by division is called the ratio of the two numbers. In this chapter we will introduce the concept of ratios and proportions.

Unitary method

The method in which first we find the value of one unit and then the value of required number of units is known as Unitary Method. In this topic we will learn to use the unitary method to solve problems involving ratios.
