III. Procedure

A. Review

Good morning class!

How are you feeling today?

That’s nice! Do you still remember our lesson about parallel and perpendicular lines?

Well, let me see if you really remember. We will have a game. Do you know “4 pics, 1 word?”

Good. I have here 4 pictures, and you are going to identify what word is being represented by the pictures. Whoever gets the correct answer will receive a prize. Understood?

Good morning Ms._________!

Good!

Yes maam!

Yes maam!

Yes maam!

First pictures.

A A R N C L UE L P P I L D

What is this? Yes Nikka?Very good Nikka. The word that these pictures shows is PARALLEL. Here is your prize.

Second Pictures.

M N I R U E RG B S C H K T

Now, Who can guess the word? Yes, Geraldine?Very good Geraldine. Let’s move to the next pictures.

Parallel.

The word is “Right”.

Third Pictures

N T A P P O LS C E K C G O

Who can guess? Yes Dexter?That’s right! So we will have our last picture.

Fourth pictures.

P U L R C N IP D S R A E E

Now, who can guess? Yes Jessie?Very good Jessie.It seems that you really know what are parallel lines and perpendicular lines. Again, What are parallel lines, Joana?

Correct! How about Perpendicular lines? Dynah?

Very well said Dynah.

The word is ANGLE.

The word is Perpendicular.

Parallel lines are lines that do not meet or intersect.

Perpendicular lines are lines that intersects and form a right angle.

B. Motivation (Look at me)

Now, I will divide you into 7 groups. This will be Group 1, …, Group 7. Form a circle now.We will have an activity entitled, “Look at me”. I will give each group a shape, and what you are going to do is to describe the shape, for example, how many corners does it has, how many sides, what kind of lines is it made of, and you will report it to the class. I will give you a cartolina and a pentelpen and you are going to write here your descriptions and paste it on the board. But reminder, be careful not to show to the other group the shape you are holding, because, we are going to use it to the next activity. I will give you 3 minutes to do the activity. Understood?

(I distribute the shapes to my students)After 3 minutes.

Okay, we will start with group 1.

Very Good Group 1.

(Up to Group 7)

C. Exploration and Discovery

Very good! Now, among the descriptions, what have you noticed? Christine?

Very Good. What do we call a polygon that has 4 sides and 4 corners, Philip?

Very good Philip.(I will paste to the board the more formal definition of a quadrilateral.)A quadrilateral is a geometric figure that has four sides and four corners.

Does the shape you are holding have 4 sides?Does it have 4 angles?So the shapes you are holding now are quadrilaterals, and the descriptions you put here on the board are its properties.

I have here a mystery bag, and inside this are quadrilaterals. Each group will choose their representative, who will be the one to pick the quadrilateral that will fit to the property that I will give. So here, you will be using your sense of touch. And the group who wrote the description that I will read will be the one to identify if the answer of the other group is correct. Understood?

So now, we will start with group six. Pick the quadrilateral which has 4 right angles.

Yes maam.

Group 1: This shape has 2 pairs of parallel sides, 4 right angles, and 4 equal sides.

All shapes has 4 sides and 4 corners.

A polygon that has 4 sides and 4 corners is a quadrilateral.

Yes it has.Yes it has.

Yes maam.

( The representative of group six will pick the rectangle)

Group 2, is she correct?Very good.

(Until all the groups were finished)

Okay. Very Good. It seems that you really understand the properties of these quadrilaterals.

D. Abstraction and Organization

Class, do you want to listen to a story?Okay. Yesterday, I was invited by a king to visit his palace. (I will paste a drawing of a palace). The name of the king is King Quadrilateral, but he is so sad. He forget the names of his sons and grandsons. He asked for our help. He wants us to identify the name of his sons and grandsons by describing each to us. Can we help him?

So to make things easier, I will give each group pictures of his sons and grandsons. After I described his sons and grandsons, what are you going to do is to raise the picture that I am describing. I will count 1 to 3, and on the third count, all of you will raise the picture. Each group who will get the correct answer will receive one point. After every description, I will ask questions and the group who can answer will receive another point. Understood?

(I will distribute the quadrilaterals to the students)

For his first son, he said, that it has two pairs of parallel sides. Who is he? 1,2, 3, everybody raise your answers!

Very good. Everybody gets the correct answer. Now, what do we call a quadrilateral that has two pairs of parallel sides? Valeriana?

That’s correct. So the first son of King Quadrilateral is Parallelogram.

Yes maam.

Yes maam!

Yes maam!

Yes maam!

(The groups will raise their answers)

A quadrilateral that has two pairs of parallel sides is a parallelogram.

Quadrilateral

Is a parallelogram a quadrilateral? Why? Yes, Dennis?Very good!(I will paste the formal definition of the parallelogram on the board)A parallelogram is a quadrilateral in which pair of opposite sides are parallel.

(The activity continues until the hierarchy is finished.)

After the activity,

Very good class. Now we already know the names of these quadrilaterals, its properties and its relationships.

Lets take a look at your scores.Group 1 IIII – IIII – IIIGroup 2 IIII – IIII – IGroup 3 IIII – IIII - IIIIGroup 4 IIII – IIII - IIIIGroup 5 IIII – IIII - IIIGroup 6 IIII – IIII – IGroup 7 IIII – IIII - II

E. Fixing Skills (Is it a fact or a bluff?)

Our next activity is entitled, “Is it a fact or a Bluff?”. I will give to you a card, with the word “FACT” written on one side and “BLUFF” written on the other side.

I will read the statement twice, and if you think the statement is true, you will raise “Fact” and if its not, you will raise, “Bluff”. I will give you 3 seconds to think and

A parallelogram is a quadrilateral because it has 4 sides.

after 3 seconds, everybody will raise their answers. Those group who will receive the correct answer will receive one point to be added to your previous points. Understood?

Okay. Lets begin. Number one, A quadrilateral is a parallelogram. Again, a quadrilateral is a parallelogram. Is it a fact or a bluff?Times up! Everybody, raise your answers.So it is a BLUFF. Very good. Everybody gets the correct answer.The following statements will be read:2. A trapezoid is a quadrilateral.3. A square is a parallelogram.4. A kite is a trapezoid.5. A trapezoid is an isosceles trapezoid.6. A square is a rectangle.7. A rectangle is a square.8. A rhombus is a square.9. A square is a rhombus.10. A rectangle is a parallelogram.

Score board:Group 1 IIII – IIII - IIII – IIIIGroup 2 IIII – IIII - IIII – IIIIGroup 3 IIII – IIII – IIII - IIII – IIGroup 4 IIII – IIII – IIII - IIII – IGroup 5 IIII – IIII - IIII – IIIGroup 6 IIII – IIII - IIII – IIIIGroup 7 IIII – IIII - IIII – IIII

F. Application

For our next activity, you are going to draw a scenario in which all the quadrilaterals are present. I will provide the drawing materials, and I will give you 10 minutes to finish the task. Then, you are going to paste your drawings on the board and discuss it to the class. The criteria will be:Creativity – 5 pointsRelevance to the topic – 3 pointsCleanliness – 2 pointsTotal – 10 points

These points will be added to your previous points and whoever gets the highest point will receive additional 5 points in the periodical exam. Understood?

(After 10 minutes, the students paste their drawings on the board and present it to the class)

Score board:Group 1 IIII – IIII - IIII – IIII + 8 =

28Group 2 IIII – IIII - IIII – IIII + 9 =

28Group 3 IIII – IIII – IIII - IIII – II

+ 9 = 31

Yes maam!

(Groups will raise their answers.)

2. FACT3. FACT4. BLUFF5. BLUFF6.FACT7.BLUFF8.BLUFF9. FACT10. FACT

Yes maam!

Group 4 IIII – IIII – IIII - IIII – I + 8 = 29

Group 5 IIII – IIII - IIII – III + 9 = 27

Group 6 IIII – IIII - IIII – IIII + 9 = 29

Group 7 IIII – IIII - IIII – IIII + 8 = 27

So the winner is Group 3!
