B. Developmental Activities
1. Motivation
“Triangle Hunt”
I have a friend named Mr. T. He is looking for his relatives. Will you help him find his relatives in the amusement park?
His relatives has the same shape as his.
What is his shape?
What does a triangle look like?
How many sides/angles do triangles have?
Can you find Mr. T’s relatives?
What can you say about the sizes/measurements of the triangles posted on the board?
Then, it only means there are different kinds of triangles
2. Presentation and Discussion of the Lesson.
a. Triangles according to sides
I have here 3 straws.
Will you measure these straws?
Connect it to form a triangle.
Now. What can you say about the sides of this triangle?
Triangles like this one are called equilateral triangle.
Based from the example, what is equilateral triangle?
I have here 3 straws again (2 straws have equal length)
Will you measure these straws?
Connect it to form a triangle.
What can you say about this triangle?
Triangles like this one is called isosceles triangle.
Based from the example, what is isosceles triangle?
I have here another set of straw (with different lengths)
Will you measure it?
Connect it to form a triangle.
What can you say about the sides of this triangle?
Triangles like this are called scalene triangle.
What are scalene triangles?
b. Triangles according to angle.
(The teacher will give triangles to the class)
Measure accurately the angle of your triangles.
Write down the measurements of the angles so that you won’t forget it.
Who holds triangle with an obtuse angle?
This triangle is called obtuse angle.
Based on its angle, what are obtuse triangle?
Who holds triangle with a right angle?
This triangle is called right triangle.
What are right triangles?
Who holds triangles with all angles acute?
This triangles are called acute triangle.
What are acute triangles?

Line segments: HC, CE, EH
Yes, we will.
Triangle
It has 3 sides and 3 angles
Yes we can.
They are different in size and measurements
They have the same length
Equilateral Triangles are triangles with equal sides.
Two of this has equal length
Isosceles are triangles with 2 equal sides
Scalene are triangles with no equal sides
Obtuse triangles are triangles with an obtuse angle.
They are triangles with right angle.
They are triangles with acute angle.
1. equilateral triangle
2. isosceles triangle
3. scalene triangle
4.obtuse triangle

III. Procedure
A. Preparation
1. Motivation- Mini Game(Boys vs Girls): Boys and girls will compete to solve picture puzzles. The pictures are related to the outer space, space exploration, etc. After the game, present the pictures and ask:
Can you identify these pictures? What do these pictures show?
B. Presentation
1. Activity
a. Film Showing: Let the pupils watch a short film about the Solar System. Encourage note-taking while watching the film.
b. Group Activity: Divide the class into 3 groups. Have the groups discuss about the film and let them answer a guide question designated to them. They will present their answers using graphic organizers.
Group 1: What are the members of the Solar System?
Group 2: What are the planets revolving around the Sun?
Group 3: What are the two groups of planets?
A group representative must present their answers to the whole class.
2. Analysis
a. Show a data retrieval chart of the basic information about the planets. Let the pupils analyze the chart and ask the following:
1. What is the planet closest to the Sun? The farthest from the Sun?
2. What is the smallest planet? The largest planet?
3. Why does the Jupiter have more moons while Venus and Mercury have no moons at all?
4. Why is there a negative sign on the revolution of Venus?
3. Abstraction and Comparison
Let the pupils fill in the Venn Diagram
Ask: What does the Venn Diagram imply?
4. Application
Give each group a copy of the crossword puzzle. They must compete each other to answer the puzzle first.
C. Generalization
Wrap up the lesson by having the pupils answer the following questions:
1. What are the members of the Solar System?
2. What is the center of the Solar System?
3. What are the 8 planets of the Solar System?
4. What are the two groups of planets?
Valuing: Ask: If given the chance, which planet will you like to live? Why?
Can other planets sustain life aside from Earth?
Explain the importance of planet Earth as our home planet. Let them mention ways of taking care of the Earth by completing the sentence: I can help taking care of our planet by ________________.
IV. Evaluation
Draw a smiley if the statement is correct and a sad face if it is wrong.
1. The Sun is the center of the Solar System.
2. The Earth is our home planet.
3. The largest planet is Saturn.
4. Jovian planets are also called inner planets.
5. The Earth is the third planet from the Sun.
V. Agreement
Draw the Solar System in a long sized bond paper. Pass this next meeting.
AYAW KAW MAGTANGIS
The man is requesting the woman to stop crying because it also breaks his heart.
Ayaw kaw magtangis
Kaugun in luha mo
Pahiri sin panyu'
Supaya makawa
Misan kaw mangasubu
Bukun da dusa ko
Dusa sin baran mo
Binin mo ako.
Timpu nakauna
Pialangga' mo ako
Buling ha bayhu' ko
Taptap piahiran mo
Misan ako natug
