Lesson Plan

A Semi-Detailed Lesson Plan

In Mathematics 4

Hazel Marie G. Gremio          

I. Objectives: At the end of the session the pupils should be able to:

            a. Identify the different kinds of plane figures;

            b. Draw plane figures correctly; and,

            c. Appreciate the shapes around us.

II. Subject Matter:

            Topic: Kinds of Plane Figures

            References: Mathematics 4

            Materials: Cutouts of different shapes, realia, activity sheets

            Values Infusion: Appreciation of things around us

III. Learning Procedure:

PowerPoint presentation

            A. Preparatory Activities

                        1. Prayer

                        2. Checking of Attendance

                        3. Review

            B. Presentation

            Do you know the song “Bahay Kubo”? Who can give me the tune of the song?

            Now, we can use the tune of the song Bahay Kubo in singing this song.

            (Teacher’s play the song)

            Song: (Bahay Kubo)

What is Mang Kiko made of? (2x)

            And            ,         ,           and           

That is what Mang Kiko made of.

            What are the figures mentioned in the song?

            Can you identify each figure?

            Then, the teacher will explain the kinds of plane figures with their characteristics.

                        Plane figures are closed figures.        

Video Presentation about what are Plane figures: http://www.youtube.com/watch?v=K5Uwcag7QaE

From the video we have seen different figures and these are:

Kinds of Plane Figures:

                        1. Triangles has 3 sides

                        2. Quadrilaterals like square (4 equal sides) and rectangle (2 sides are equal and the other 2 sides are equal which shorter than the other side’s) has 4 sides.

                        3. Circles

2. Group Activities

            Divide the class into 4 groups. Then give the instructions and materials.

Group1: Tracing the dots

a. Trace the dots and identify the figure.

b. Describe the figure

 Activity Sheets: 1, 2, 3, 4

Group 2: Writing

 Write Z inside the figure with 3 sides, Y inside the figure with no sides and x inside the figure with 4 sides.

Activity Sheets

Group 3: Human figure

a. Let the pupils form a figure with 4 sides, a figure with 3 sides and a figure with no sides

b. Describe each figure

Group 4: Naming figures

Name some things inside the room with the following:

a. figures with no sides

b. figures with 4 sides

c. figures with 3 sides

After 20 minutes, let each group present their outputs.

C. Comparison and Abstraction

            Ask the pupils: Are the figures the same? Why are the figures the same?

                                    Is square and triangle the same? Why?

            (Thumbs up, thumbs down)

Ask:

 1. Is a Triangle a 3 sided figure?

            2. Is square a 3 sided plane figure?

D. Application

            “Bring me Game” (Horse race)

Let the pupils bring things that can be find around the classroom according to what the teacher wants to bring by the pupils the first one will have their reward.

E. Generalization

            What do we call a closed figure with no sides? How about a figure with 3 sides? What about with 4 sides?

            Plane figures are closed figures. Plane figures with 3 sides are called triangles. Those with 4 sides are called quadrilaterals; those without sides are called circles.

IV. Evaluation

            Write your answers in ¼ sheet of paper.

Count the number of plane figures in the illustration:

 1. How many quadrilaterals are there?

2. How many circles are there?

3. How many triangles are there?

4. How many plane figures are there, all in all?

V. Assignment

Draw a robot/doll that made up of different plane figures. You can use different art materials. Put it on a short coupon bond

 For example: Figure1
