Instructional Procedure:
A. Preliminary Activities
 Prayer
 Checking of Attendance
 Checking of Assignment
1. Drill
Identify whether the following is a point, a ray, line segment or a line.
2. Review
Game” What am I“
a. I have an exact location in space . I am represented by a
dot.
b. I have no endpoint and I can go on and on in opposite
directions.
c. I start out at a point and can be extended in one direction.
d. I am part of a line with 2 endpoints.
3. Motivation
Picture or imagine yourselves in front of the flagpole forming lines for
the flag raising ceremony.
A. How should you form your lines?------------------------------------B. Why do we always have to form our lines in an orderly
manner?--------------------------------------------------------------------C. What will happen if we don’t form our line properly?--------------------------------------------------------------------------------------------D. What should we always remember in forming our lines during
flag ceremony?-----------------------------------------------------------B. Developmental activities
1. Presentation
Game on “Forming Lines”
a) All those whose birth month is in December will form 2 straight
lines.
b) All those who are wearing a pants will form 2 lines that meet at
the center.
c) All those whose birth month is March will form one line and
another line for those who were born in October . Then , form 2
lines that show square corners.
2. Activity
Divide the class into three groups. Each group will work together
in illustrating the given figures to show the different kinds of lines using
cutouts then present your output.
Group 1: Crossroads
Group 2: Time using the hands of the clock
Group3 : Design of a T-shirt(example : checkered , striped
3. Analysis
a. How did you find the activity?
b. How were you able to illustrate the figure given to you?
c. Did you cooperate with your group mates?
4. Abstraction
What are the different kinds of line that we made today?
What is a parallel line?
What is an intersecting line?
What is a perpendicular line?
5. Application
Illustrate the following kinds of line:
a. parallel line
b. intersecting line
c. perpendicular line
IV- Evaluation
Draw three objects on each line.
a. Parallel line
b. Intersecting line
c. Perpendicular line
V-
Assignment:
