A Semi Detailed Lesson Plan in Math 5
I. Objectives
a. The learner is expected to demonstrate understanding of circles
b. The learner is able to describe construct circles
c. Draws circles with different radii using a compass Code: M5GE-IIIe-24,
IV. Procedures
A. Reviewing previous lesson
What is polygon ?
Is Circle a polygon?
B. Motivation
activity:
Students will be group into 3
give each group a string
Each group will chose one representative to stand in front of them holding the other
end of the string around to form a circle, placing other members evenly on the
imaginary distance around the circle
What figured is formed?
What does the pupil in the middle represent?
C. Lesson proper
A circle is the set of all points in a plane with the same distance from a certain point
called the center of the circle.
A compass is an instrument to draw a circle or an arc. It is made up of two moveable
arms hinged together where one arm has a pointed end and the other arm holds a
pencil.
Radius- is a segment that connects the center point to any point on the circle. it is
also half of the diameter. The plural form of the radius is a radii
Diameter- is a segment that connects two points of a circle and passes through its
Center. It is the longest chord of a circle.
Chord- is a line segment that connects any two points on a circle.
Circumference- it is the distance around the circle, or one complete are with the
same start and end point.
Activity Time:
draw a circle with a center at A and a radius of 2 centimeter.
first, set up compass to an opening of 2cm.
second, draw point A with a pencil. Next compass to draw the circle.
We now have a circle A. Let us put some radii. from the center, draw a segment to
any part of the circle.
Generalization:
Always remember that circle is the set of all points in a plane with the same distance
from a certain point called the center of the circle.
A compass is an instrument to draw a circle or an arc. It is made up of two moveable
arms hinged together where one arm has a pointed end and the other arm holds a
pencil.
