IV. PROCEDURES
A. Reviewing or ACTIVITY: PICTURE ANALYSIS
presenting the new
lesson Note to the Teacher:
The teacher will provide at least three pictures.
Divide the class into five groups (each group will use THINK,
PAIR and SHARE strategy).
Provide each group with pictures.
Let the learners identify the difference of the pictures
Guide the students to answer the following:
What is/are the picture?
What have you observed on the picture?
Note: The teacher must lead the students to the concept of “Factoring
with the common monomial factor”
(answers may vary)
C. Presenting examples ACTIVITY: Do we have a common?
of the new lesson
Identify the common term of each polynomial through prime
factorization.
1. 2ab + 2ac – 2a
Ans. 2a
2. 20x2 – 12
Ans. 4
3. x(a-b) + y(a-b)
Ans. (a-b)
Ask the following:
What are the prime factors of each term?
What is the common factor?
How did you identify the common factor?
D. Discussing new BIG IDEA!
concepts and
practicing new skills The teacher will discuss this statement.
#1
Common monomial factoring is the process of writing a polynomial
as a product of two polynomials, one of which is a monomial that
factors each term of the polynomial.
Every expression has itself and the number 1 as a factor. These are
called the trivial factors. If a monomial is the product of two or more
variables or numbers, then it will have factors other than itself and 1.
A. B.

4. 5y2 + 10 Ans. 5(y2 + 2)
5. 14p2 + 21 Ans. 7(2p2 + 3)
J. Additional Teacher will ask the students:
Activities for
application or What do you think is the amount of courage needed to make up for a
remediation shortcoming? (Answer may vary).

Directions:
This activity will give you an idea on how factors
associated with products. You will match the factors in column A with the
products in column B to decode the secret message.
