2. Review
Last time youve learned the
different kinds of angles.
What is an angle?
What are the different kinds of
angles?
Id like you to tell the angle
formed by the hands of the clock.
What angle is formed when the
hands strike 3:00?
3:30?
5:50?
6:30?
1:30?
6:00?
Very good!
3. Motivation
In a sheet of paper, draw one
thing that you can see inside the
classroom. Ill give you ten
minutes to do it.
(Teacher collects the pupils
output).
I will draw three papers. Come to
the front and tell something on
your drawing.
Right angle
Right angle
Acute angle
Obtuse angle
Acute angle
Obtuse angle
Straight angle
(Pupils draw).
What is a circle?
Is a circle a polygon?
Therefore, a circle is not a polygon
but a plane figure.
Where can you find plane figures?
3.Fixing Skills
Fill up the chart on the board.
Write the name of the plane
figure, then draw and write the
number of its sides and angles.
(Teacher calls pupils name to fill
up the chart).
4.Generalization
What is a plane figure?
What are polygons?
Where are the line segments in a
plane figure?
