Chapter_5_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.

Chapter_3_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

Chapter_2_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'.

Chapter_11_Algebra

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

Chapter_14_Practical_Geometry

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

Chapter_9_Data_handling

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

Chapter_10_Mensuration

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

Chapter_4_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.

Chapter_7_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.

Chapter_13_Symmetry

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

Chapter_1_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!

Chapter_8_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.

Chapter_6_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'.

Chapter_12_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.
