CLASS: FORM 3
TOPIC: SIMPLIFYING ALGEBRAIC EXPRESSIONS
DURATION: ONE PERIOD (45 minutes)
Preknowledge
 Recall the rules of Directed Numbers
 Identify the components of an Algebraic Expression

Objectives
At the end of the lesson students should be able to
 Identify the like terms in an algebraic expression
 Add/subtract the like terms to reduce the expression

Activity
An algebraic expression would be displayed on the board and students would be asked to determine:
 How many terms make up the expression
 Identify the variable, coefficient and power of each term

Key points
To simplify an algebraic expression operate on the coefficients of the like terms

Definition
Like terms  terms which have the same variable and the same power.

Five algebraic expressions will be presented to the students one at a time where students are asked to identify the like terms and put these like terms into groups by using brackets.
Of these five problems, there will be one case where there are no like terms.
Activity
Students are asked to work in groups of five where they are given cards with terms and expressions and are asked to:
 Identify the like terms
 Group them into brackets
 Operate on their coefficients to reduce the expression

Case Study
In the case where the expression has no like terms, what do we do?

Assessment
Groups are asked to present their findings and strategy for simplifying the expressions
Students are presented with five more problems to work on individually

Summary
Students are selected at random and are given the task of reviewing the salient points of the lesson by guided questioning.
Students are directed to the websites stated above
