A Detailed Lesson Plan in Math 4 I. Objective: At the end of the lesson, 75% of the Grade 4 pupils are expected to: 1. name different kinds of angles such as right angle, acute angle and obtuse angle 2. construct different kinds of angles 3. participate actively in group activity II. Subject Matter: Topic: Angles Skills: Naming different kinds of angles Constructing different kinds of angles Reference: BEC-PELC III.A.2.2, 2.2.1 Materials: Colored name tags, strips, rulers,improvised protractors, cartolina, flash cards, mat Value: Cooperation III. Strategy: Teacher’s Activity
Pupils Activity
A. Preparatory Activities (Expose) 1. Drill Class, I have here on the board pictures of Angles. Now, who among you can give at least 3 angles?
Pupils raise their hands FLA ALC YLF
Very Good! Okay, let’s look at the angles, what do you think is the vertex of all the angles?
L
2. Review: Base on the drawing, what are the parts of an angle?
An angle has two parts: the sides and the vertex.
3. Motivation: Okay, now that you know the different parts of an angle. Let’s have a contest, group yourselves according to your color. The winners in the contest will have a prize. Pupils do so. B. Developmental Activities: 1. Presentation: Our lesson for today is about angles. 2. Discussion: (Explore)
Group Activity: (Given time 7 minutes) Pink Group Instructions: draw Pinoy Big Brother’s house, using only the rulers and the pentel pen.
Pupils do so.
Green Group: Instructions: draw a house where your pet dogs can live, using only the rulers and the pentel pen.
Pupils do so.
Yellow Group: Instructions: draw a big boat using only the rulers and the pentel pen.
Pupils do so.
Okay, now let’s ask the pink group to present to the class their drawing. (teacher labels the sides of the house) Class try to look at the angle formed at the base of the house. It looks like a square corner. This angle is what we call the right angle. What do you think is the measure of the right angle?
900
Correct! Now let’s ask the green group to present to the class their drawing. (teacher labels the side of the rooftop) Class try to look at the angle formed at the side of the houses’ roof. Which angle do you think is smaller, the right angle or the new angle? Correct! This angle is what we call an acute angle.
The new angle.
What do you think is the measure of the acute angle? Is it greater than or less than the right angle?
Less than 900
Correct! Now let’s ask the yellow group to present to the class their drawing. Class try to look at the angle formed at the side of the ship. Which angle do you think is bigger, the right angle or the new angle? Correct! This angle is what we call an obtuse angle. What do you think is the measure of the obtuse angle? Is it greater than or less than the right angle? (Experience) Now class, how will we know that the measure of an angle is 900? What tool will we use to measure an angle?
The new angle.
Greater than 900
Use a protractor.
(Teacher presents a protractor and distributes copies to the class) Class do you know how to use a protractor?
No!
To measure an angle, place the arrow of the protractor at the vertex of the angle and the baseline of the protractor along one side of the angle. Then read the number of degrees from the side of the angle. Class let’s measure the angles of your drawings using the protractor. Now class lets have another game. Let’s ask each group to have 2 volunteers in front. I have here some flashcards, as I flash the cards you’re going to form an angle using your bodies.
Pupils do so.
Pupils do so.

90o Group cheer for your . 3. Analysis: So, looking at your classmates what kind of angles did they form? Are the angles the same? Do they have the same measurements? 4. Generalization: What are the three different kinds of angles? What is a right angle?
Acute angle, right angle and obtuse angle No! No! Right angle, Acute angle, Obtuse angle An angle that measures 90o
What is an acute angle?
An angle that measures less than 90o
What is an obtuse angle?
An angle that measures greater than 90o
5. Application: Look at the drawing on the board. Name as many angles as you can find. Tell whether the angle is right, obtuse, or acute.
