SUBJECT AREA	Geometry	QUARTER	Third
YEAR LEVEL	Year III	DURATION	3 days/wk
SCHOOL YEAR	2012-2013	Number of Minutes	60/ Period
PREPARED BY:	Ronith Nikki Pacis

I. Objectives

At the end of the lesson, the students will be able to:

A. To be familiar with Euclidean transformations.
B. To distinguish reflections, translations, and rotations.
C. To prove theorems related to transformations.
D. To solve problems involving transformations.
E. To apply transformations to real-world situations.
F. To make designs using transformations.

(The students shall engage in learning process and shall study the Euclidean transformations and differentiate the types of it. In the process, they shall prove theorems and solve problems. To activate what they have learned then, they shall apply transformations in real world and make designs using transformations.)

I. Subject Matter

Geometry (Transformations)

· Reference: Geometry for Highschool Textbook

· Materials: sheets of paper, protractor, tangram puzzles

colored paper

· Values: creativity, determination, patience, resourcefulness,

obedience

(The students shall be provide the materials needed for their activities, we can tell how obedient the students by complying on the said materials needed and also how resourceful they are for some might use other materials.)

II. 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 18-1

· Theorem 18-2

· Theorem 18-3

· Theorem 18-4

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 Ma’am!”

(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)

(Students raise their hands and define the terms)

(Students listen attentively)

(Students perform)

(Before the class begins we shall start the class with a prayer for the honouring of our Divine Creator.

I shall check the attendance (monitoring student’s performance) then, I shall ask them to clean their places to help them concentrate on the run of the discussion (pleasant learning environment)

* Presentation

I chose the folding of paper as our activity since:

Ø It teaches students how to follow directions,

Ø encourages cooperation among students,

Ø improves motor skills, and

Ø it helps develop multi-cultural awareness.

Ø It can be a great source of fun for students and

Ø To make the discussion of lesson less serious

Ø It exercises hand muscles of students

While on tracing of shapes:

Ø It incorporate color recognition, fine motor skills, numbers, and concepts such as large and small.

* Discussion

This section is divided in steps

Step 1: Pre-listening

Here, I shall point out to my students that Geometry is not only a study of figures but also its movement. And I shall give them the following principle questions:

Is the original figure congruent to the other figures?

How does the second image compare to the original figure?

Step 2: Participation

I shall ask some volunteers in the class to compare the figures in the board

Step 3: Comprehension Questions/Terms

I shall give sets of terms and I shall ask them to define each. Also, I shall give them different theorems and ask them to tell about it.

Step 4: Discussion Principle Questions

We shall then, answer the principle questions I provided at the beginning of the class and discuss the figures in the board.

Step 5: Post Discussion

We will discuss the definitions and we will prove the theorems

Step 6: Activities

I shall ask the students to form into groups
Group work enhance the student’s learning through a collaborative process, aside from that they shall value placed on teamwork skills, also it saves time and energy

III. Evaluation

Did students:

1) Learn to differentiate reflections, translations, and rotations?

2) Learn to prove theorems regarding Transformations?

3) Value creativity, determination, patience, resourcefulness, obedience

4) Learn how to make use of Transformations in real life?

(I shall observe my students first. Before I end the class, I shall ask them if they have clarifications or any questions in mind. And then, if ever there are, I shall resolve it by clarifying them out. I shall also ask if everyone has followed the flow of the lesson, if they learned or they have some difficulties understanding some parts of the lesson.)

          Assignment

          Drawing
          The student will use transformations to move figures and create designs.

(With their assignment I shall be able to know if my students have learned and I can test the results of evaluation also through this.)
