2. “Teaching is the noblest of all professions. Teachers
should be
proud of their calling, knowing that not all people are
capable
of being teachers, for many are called, but few are
chosen.”
CD. Duka

Concepts:
According to Wikipedia, an Algebraic Expression is an
expression built up from integer constants, variables, and the algebraic
operations (addition, subtraction, multiplication, division and
exponentiation by an exponent that is a rational number). For example, 3x2
– 2xy c is an algebraic expression.
A rational algebraic expression is an algebraic expression that
can be written as a quotient of polynomials, such as x2+4x+4. An irrational
algebraic expression is one that is not rational such as 𝒙 + 𝟒.

Definition of Terms:
 A numerical expression is an expression that combines numbers and
one or more operation symbols.
 A variable is any letter or symbol that represents a number.
 A constant has a fixed value that does not change.
 An algebraic expression is a mathematical phrase that uses variables,
numerals and operation symbols.

III. Procedure:
Directions for the activities:
 Group the class .
 Choose the officers for the activity.
 The teams will be given worksheets that they should follow.
 They need to make sure that the basic elements of Cooperative
Learning is present in the activity.
 The teams will be given 20 minutes to discuss the problem and come
up with the answer s and 10 minutes each in presenting their answer.

10. ALGEBRAIC EXPRESSION
III. Procedure:
WARM UP ACTIVITY
Ask:
 What is algebraic expression?
 What is the use of algebraic expression in your day to day life?
 Imagine a fare for the first 4 km is P8.00 and an additional P1.00 for
every kilometer. Richie will go to Cubao from Antipolo and the distance
is about 28 km. How much does she need to pay?

11. ALGEBRAIC EXPRESSION
III. Procedure
WARM UP ACTIVITY
 Group the class into two. From the given problem, each will be
presented with the answers but they need to make sure they will
choose the correct ones. They need to choose wisely.
 After discussing their answer, each will present and will be given
evaluation forms to rate their performances.
 Their answer may be posted in the board for the class to see.

12. ALGEBRAIC EXPRESSION
III. Procedure:
ACTIVITY 1
 Group the class into three.
 The students will then arrange their chairs and face their classmates.
 The teams will be given worksheets to be answered.
 A recorder will write the team’s answer.
 And a reporter will report it after they’re done.

13. ALGEBRAIC EXPRESSION
III. Procedure:
ACTIVITY 2
 Group the class into four.
 Ask a representative for each team to be in the expert group.
 The expert group will then discuss the topic including the answers of
the problem.
 And then the expert members will go back to their respective group to
discuss the answer with their teammates.
 After the discussion, the reporter will then present the team’s answer to
the class.

14. ALGEBRAIC EXPRESSION
III. Procedure
Reporting(Discussion of the result of each activity):
 How did you translate word phrases into algebraic expressions?
 How did you translate algebraic expression into word phrases.
 How do you solve algebraic expression problems?

15. ALGEBRAIC EXPRESSION
III. Procedure
Generalization:
Algebraic Expression is a mathematical phrase that uses
variables, numerals, and operation symbols. A numerical expression is an
expression that combines numbers and one or more operation symbols. A
variable is any letter or symbol that represents a number. A constant has a
fixed value that does not change.
Algebraic Expression is basically used in all facets of life. It can
be used in getting the price of our shirts, the payments from our jeepney
fares or our body weights in kilograms. Word phrases and algebraic
expressions are necessary to solve those real life situations we encounter
everyday. To translate word phrases into algebraic expression, familiarity
with words and phrases associated with symbols or operations are
important.

16. ALGEBRAIC EXPRESSION
IV. Evaluation:
Romar is twice as old as Mavic. If Mavic is q years old,
Jaypee is 2 years older than Romar.
a. If Mavic is q years old, how old is Romar algebraically?
b. Express Jayvee's age algebraically.
c. Write an expression for the sum of Romar and Mavic
ages.

17. ALGEBRAIC EXPRESSION
V. Assignment:
Formulate three intellectually challenging
situations where algebraic expressions can be
applied in real life.
