A number is a mathematical value used to numerate and measure various objects. Using the numbers we all can add, subtract, divide and multiply.
Here we'll learn how to compare numbers, expand the number, and also learn about the smallest and the largest numbers.
In mathematics, the whole number set is the most basic number set. This set contains the counting numbers 1, 2, 3,… and the number 0. This chapter begins with the discussion of the definition of whole numbers and natural numbers. You will be learning to differentiate between the whole numbers and the natural numbers. It teaches you that all whole numbers cannot be natural numbers, but all natural numbers are whole numbers.
Playing with Numbers comprises different fundamental concepts for building a solid conceptual foundation. In this chapter, you will be learning various concepts like factors and multiples, composite and prime numbers, common factors and common multiples, prime factorization, highest common factor (HCF) and lowest common factor (LCM).
Several important geometric terms that hold extreme importance in later grades are included in this chapter. The topics introduced will not only help build a foundation in geometry but will also help to easily grasp the higher-level concepts in the later grades. The main themes covered here are - basic geometry, polygons, triangles and quadrilateral.
This chapter deals mostly with the measurement of line segments, angles and their types, triangles and their classifications, polygons, quadrilaterals, and solid forms.
A fraction represents a part of a whole or generally, any number of equal parts. Some of the important concepts that you will be learning in this chapter includes Types of Fractions, Addition of Fractions, Subtraction of Fractions, Multiplication of Fractions, Comparing Fractions, Simplest Form of Fractions and Representation of Fraction on a Number Line.
