PRE- REQUISITE KNOWLEDGE:-
Students should have prior knowledge of variables, expressions, and equations. They should be familiar with basic operations such as addition, subtraction, multiplication, and division.Students should have a grasp of exponent notation and the concept of raising a number to a power. They should be familiar with the rules of exponents, such as multiplying and dividing exponents.
Students should have experience simplifying algebraic expressions by combining like terms and performing basic operations.
They should be able to factor simple expressions, such as finding common factors.
They should be comfortable with using arithmetic skills to evaluate expressions.

KEY WORDS:
Algebraic Expressions, Algebraic Identities, FactorizationCONTENT OF THE TOPIC
(a - b)^{2} = a^{2} - 2ab + b^{2}
(x + a)(x + b) = x^{2} + (a + b)x + ab
(a + b + c)^{2} = a^{2} + b^{2} + c^{2} + 2ab + 2bc + 2ca
PROCEDURE OF THE LESSON PLAN
Introduction
Greet the students and
introduce the topic of algebraic identities. Ask the students if they have
heard about algebraic identities before and encourage them to share their prior
knowledge.
Conceptual Understanding
Explain the definition of
algebraic identities: statements that are true for all values of the variables
involved.
Present some common algebraic
identities, such as:
(a - b)^{2} = a^{2} - 2ab + b^{2}
(x + a)(x + b) = x^{2} + (a + b)x + ab
(a + b + c)^{2} = a^{2} + b^{2} + c^{2} + 2ab + 2bc + 2ca
Discuss the meaning and
significance of each identity, providing examples and asking the students to
find patterns.
Encourage students to ask
questions and participate in the discussion.
Distribute worksheets with
various algebraic expressions involving the identities discussed.
Instruct students to simplify
the expressions using the appropriate algebraic identities.
Walk around the classroom,
providing assistance and checking for understanding.
After students have completed
the worksheets, review the solutions as a class, discussing different
approaches and addressing any misconceptions.
Present real-life problems
that can be solved using algebraic identities.
Guide students in identifying
the relevant identity and setting up the equations.
Allow students to work
individually or in pairs to solve the problems.
Ask a few students to share
their solutions with the class, discussing the process and reasoning behind
their approaches.
Summarize the main concepts covered in the lesson.
Review the algebraic identities and their applications.
Address any remaining questions or concerns from the students.
Assign relevant exercises for homework to reinforce the understanding of
algebraic identities.
Extensions:
For advanced students,
introduce more complex algebraic identities and challenge them to apply them in
problem-solving scenarios.
Integrate technology by using
graphing calculators to demonstrate the application of algebraic identities in
graphing and analyzing functions.
