This document provides an introduction to algebra. It outlines the objectives of understanding variables, expressions, equations and manipulating algebraic expressions. It defines key terms like expression, equation, variable and constant. The document includes two activities to demonstrate significance and examples are provided for parts of algebraic expressions. Reasons for teaching algebra are that it develops logical thinking and provides access to intellectual concepts. Common misconceptions are addressed through an algebraic story. The importance of ensuring understanding over coverage is emphasized.

4. Curriculum Alignment
• Introduction to Algebra
• Algebraic Expression, Equation & Identities
• Factorization of Algebraic Expression
• Basic Algebraic Formulas
• Manipulation of Algebraic

5. OBJECTIVES
To enable students to:
• Understand the language of algebra (use of letters of the alphabets to
represent numbers).
• Differentiate between Variables & Constants.
• Substitute numbers for letters of the alphabet in expressions and
formula.
• Manipulate simple algebraic expressions

6. What is Algebra?
The part of mathematics in which letters and other general
symbols are used to represent numbers and quantities in
formulae and equations.

7. Term : A word or phrase used to describe a thing or to
express a concept
Expression : It is a mathematical sentence; it doesn’t have
an equal sign
Equation: It is a complete Mathematical sentence that
includes a sign of equality

8. Parts of Algebraic Expression

9. Variable:
A variable is a symbol which represents a quantity that can
vary.

10. Constant
A constant is a symbol which represents a specific number
(a quantity does not vary).
Coefficient
The number that is multiplied by the variable.

12. Significance of Algebra
In the primary curriculum algebra can be seen as the
development of children’s ability to think and reason logically
and systematically.

13. Activity 2
Steps:
1. Think of a number
2. Multiply it by 2
3. Add 10 to the number
4. Divide total by 2
5. Subtract total form number u picked

14. Answer will be

15. Why we Teach Algebra?
We teaches algebra because , our real duty as teacher is not
merely to prepare our students for some “Real World” , and it
certainly is not merely to prepare them for workplace.
If we deny them access to algebra we deny them access to an
entire intellectual universe.
We Teach algebra to provide students all entire intellectual of
universe

17. An Algebraic Story

19. The greatest enemy of understanding is coverage. As long as
you are determined to cover everything, you actually ensure
that most kids are not going to understand. You’ve got to
take enough time to get kids deeply involved in something so
they can think about it in lots of different ways and apply it –
not just at school but at home and on the street and so on.
(Brandt, 1993)
