					Illustrating Division as Repeated Subtraction

I.     Learning Objectives

       Cognitive: Illustrate division as repeated subtraction
       Psychomotor:Draw simple objects to show division as repeated subtraction
       Affective:  Enjoy drawing common objects around them

II.    Learning Content

       Skill:         Illustrating division as repeated subtraction
       Reference:     BEC PELC I E 1.3.3
       Materials:     flash cards with division sentences and parts of a division sentence written on
                      them, activity cards
       Value:         Cheerfulness

III.   Learning Experiences

       A.       Preparatory Activities

                1.    Drill

                      Tell the quotient of the number senetnce after mentioning its repeated
                      subtraction.


                2.    Review

                      What part of the division sentence is the encircled number?


                          32 / 4 = 8                10 / 5 = 2                12 / 6 = 2

                           8/2=4                    16 / 8 = 2                25 / 5 = 5

                                       42 / 7 = 6                81 / 9 = 9




                3.    Motivation

                      Have the pupils group themselves into 8s.
                      (To the teacher: The number of groups depends upon your enrolment. The lesser
                      the number of groups formed, the better.)
B.   Developmental Activities

     1.    Presentation

           Ask:
           – How many are you in all?
           – Into how many groups did you form yourselves?
           – What division sentence can you write? 40 / 8 =
           – Find its quotient through repeated subtraction.

                                  40
                           1   - 8        40 / 8 = 5
                                  32
                           2   - 8
                                  24
                           3   - 8
                                  16
                           4   - 8
                                   8
                           5   - 8
                                   0
           - How many times did we subtract? The number of times that we subtracted 8
             from 40 is the quotient.


     2.    Group Activities

*Valuing:
– How did you feel while drawing and coloring your work?
– Were you happy?
– How should we feel while working?
               3.     Generalization

                      - How can you illustrate division as repeated subtraction?

       C.      Application

               Draw fruits to show division as repeated subtraction. Group them according to the
               number of members in your family. Then write the subtraction sentence and the division
               sentence.

IV.    Evaluation

       Darw objects inside the box and show division as repeated subtraction by encircling thye
       objects.

       1) 4 / 2 =             3) 8 / 2 =           5) 15 / 5 =




       2) 8 / 2 =             4) 8 / 2 =




V.     Assignment

       Ring the objects to show division as repeated subtraction. Then write the subtraction sentence
       and division sentence.

      1.                                     4.
