Procedure
A.
Learning Activities
Teacher’s Activity
“Good Morning Class...”
“Let us pray first...”
(Checking of Attendance)
...say present...
“Please pick up
the pieces of paper
under your
chair”
Presentation
Activity  Folding of Paper The teacher will give an activity that involves the folding of paper and tracing of shapes. Discussion From the activity, the teacher will point out that geometry is not only the study of figures but is also the study of the movement of figures.
·
Is the original figure congruent to the other
figures?
·
How does the second image compare to the original
figure?
Input
Definitions:
·
Transformations
·
Reflection
·
Rotation
·
Translation
·
Dilation
·
Rigid Motion
Theorems:
·
Theorem 181
·
Theorem 182
·
Theorem 183
·
Theorem 184
·
Discussion
The
above definitions and theorems will be discussed and proved. The teacher will
ask the student to give examples of transformations.
D.
Activity
Tangram Puzzle The students will form six groups. Each group is going to make images of animals using tangram puzzle and they will identify the kind of transformation depicted or made after doing the activity. 
Student’s Activity
“Good Morning Sir!”
(One Student will lead the
Prayer)
(Students raise their hand
and say present as the teacher calls in their name)
(Students pick up the pieces of paper)
(Students follow the instruction of the teacher)
(Students listen
attentively)
(Conduct a solving on the
board)
(Students raise their hands and define the terms)
(Students listen
attentively)
(Students
perform)

IV.
Evaluation
Worksheet
1. Which of the following transformations creates a figure that is similar (but not congruent) to the original figure?
2. How can transformations be applied to realworld situations?
III. Assignment
Drawing
The student will use transformations to move figures and create designs.
