    III. Procedure

    a. Preliminaries

    Teachers Activity Students Activity


    1. Prayer
    One of the student will lead the prayer
    To start our class , let us all stand for
    prayer

    2. Greetings
    Good morning ma'am !
    Good Morning class!

    3. Checking of attendance
    Yes ma'am !
    Say present as I call your name,

    4. Review

    Our lesson last meeting was all about


    What was our lesson last meeting ? subracting of Monomial

    -2
    1. 2-4= ? 13
    2. 4-(9)=? 4
    3. -3-(-7)= ?

    b. Motivation

    Before we proceed to the next topic,


    let's have our first activity .
    Group yourself into three and answer
    the given puzzle.

    Group 1 will answer number 1, group 2


    will answer number 2 and group 3 will
    answer number 3.
    SUBTRACTION
    1. TIONRACTSUB POLYNOMIALS
    2. SLAIMONYLOP MATHEMATICS
    3. SCITAMEHTAM
    Subtraction of Polynomials
    Based on the activity, what do you think
    our next topic?
    Very Good!

    1. Presentation of the Lesson


    *An algebraic expression where all
    What is polynomials variables when expressed in the numerator
    have nonnegative integral experience
    exponents.

    *Is an algebraic expression which contains


    more the one term.

    Do you have any idea on how to subtract No ma'am !


    polynomials?

    It's just like subtracting integers, first we


    have to change the sign of all the terms
    of the subtrahend and go back to the
    addition rule.

    In this equation 5x² + 2x - 3 minus 4x² + 4x² + 2x - 7


    2x - 7, where is the subtrahend?

    Very good!

    We have to change the signs of all the


    terms of the subtrahend, so
    4x² will be ? -4x²
    2x² will be? -2x²
    And -7 will be ? +7

    So the equation of the subtrahend is


    now -4x² -2x + 7. Then we will change
    the operation sign from minus to plus.

    5x² + 2x - 3 plus -4x² - 2x + 7 is x² + 4.

    Understood ? Yes ma'am !

    Example:
    ( 4a³ - 2a² + 5a + 7 ) - ( 3a³ - 8a² - 9a -
    14)
    (4a³ - 2a² + 5a + 7 ) + ( -3a³ + 8a² + 9a +
    14)
    = a³+6a²+14a+21.

    Do you have any question ? If none, we


    will proceed to the next activity.
    Students form into 3 groups and perform
    the activity.
    2 . ACTIVITY
    (GROUP ACTIVITY)
    Please group yourself into three.
    Group 1 will answer no.1
    Group 2 will answer no. 2
    Group 3 will answer no. 3 2a²+5a-9
    -4x⁴+2x³-6x²+6x+6
    1. ( 3a²+2a-2) - ( a²-3a+7)
    2. (-2x⁴+5x³-2x²+3x+1) - ( -5x⁴+9x³-7x-7
    2x⁴+ 3x³+4x²-3x-5)
    3. ( 13x⁴-5x-18) - (
    18x⁴-9x³+2x-11)

    3 . ANALYSIS

    What is the process and concept of


    subtracting polynomials?

    4 . ABSTRACTION

    Using the rule of the subtraction, which


    is to change the sign of all the terms of
    the subtrahend and the operation. From
    minus sign to plus sign. Copy the sign of
    the bigger number.

    5 .APPLICATION
