Introduction To Algebra
Chapter 2
INTRODUCTION TO ALGEBRA
Learning Objectives
● To describe, extend, create numeric and geometric
patterns.
● To make predictions related to the patterns and
investigate repeating patterns.
● To understand the role of 'variables' in patterns.
● To use variables in simple algebraic expressions
and equations to describe relationships.
Introduction
Are you ready for a number game? Follow the steps
below carefully:
Is your answer 10? Is it the same for all in the
class? Verify it with your friend who might have started with a number other than
your number. Surprised? What if you started with a fraction, say 1/2 or 3/4 or 5/4
? In this game, regardless of the number you started with, the answer will be 10.
Let us verify the game for two more numbers, say
4 and 9.
● If the initial number is 4,
● If the initial number is 9,
So, we can say that the same will happen for other
numbers too.
You will find that Algebra is interesting and useful
in solving problems in our daily life such as
● Finding the number of things to its cost.
● Expressing the distance covered, in terms of speed
and time.
● Converting miles into kilometres, grams to kilograms
etc.
● Finding the length of the barbed wire to fence a
garden.
● Finding the area of a park.
● Finding the missing numbers in a sequence.
