B.   Developmental Activities
1.    Motivation
Find four-sided polygon in the picture
 (Show a picture of a playground  with various kinds of quadrilateral)
Let them figure 4 sided polygons as much as they can. 


2.    Discussion of the lesson
I will distribute envelops with activity cards  inside. Each group must work out on the group activity.

Activity card – Group 1

Look at the figure

 (Figure of a parallelogram labeled A< B< C< D)
 




1.    How many sides does this figure has?
2.    Look at side AB and CD. Are they parallel with each other?
How about side AC and BD? What can you say about them?
Therefore, how many pairs of parallel sides are there?
3.    Measure side AB and CD. Do they have the same measurement?
How about side AC and BD? What can you say about their measurement?

This figure is called parallelogram. What can say about parallelogram?




Activity Card – Group 2

Look at the figure.



 (figure of a rectangle labeled a, b, c,d)

1.    How many sides does this figure has?
2.    Look at side AB and CD. Are they parallel with each other?
How about sides AC and BD? What can you say about them?
Therefore, how many pairs of parallel sides are there?


3.    Measure side AB and CD. Do they have the same measurement?
How about side AC and BD? What can you say about their measurement?


4.    What can you say about their corners/angles? What is the measurement of their angles?

This figure is called rectangle. Rectangle is a kind of parallelogram.
What can you say about rectangle?


Activity card – group 3

Look at the figure.


( figure of a square)


1.How many sides does this figure has?
2.Look at side AB and CD. Are they parallel with each other?
How about sides AC and BD? What can you say about them?
Therefore, how many pairs of parallel sides are there?
3.. Measure the sides of this figure. What can you say about it?
4. What can you say about their corners/angles? What is the measurement of their angles?

 This figure is called square. It is a kind of parallelogram.
Describe the characteristics of square.

Activity Card – Group 4
Look at  the figure.

 Figure of a rhombus




1.How many sides does this figure has?
2.Look at side AB and CD. Are they parallel with each other?
How about sides AC and BD? What can you say about them?
Therefore, how many pairs of parallel sides are there?
3.Measure the sides of this figure. What can you say about it?

This is called rhombus. It  is a kind of parallelogram.
What can you say about rhombus?




Activity Card – Group 5

Look at the figure.
 


 (figure of trapezoid)

1.How many sides does this figure has?
2.Look at side e AC and BD. Are they parallel with each other?
How about sides AB and CD? What can you say about them?
Therefore, how many pairs of parallel sides are there?

This figure is called trapezoid/trapezium.
What is a trapezoid?

Activity Card – Group 6


 (figure of a irregular polygon)

1.How many sides does this figure has?
2.Look at side AB and CD. Are they parallel with each other?
How about sides AC and BD? What can you say about them?
Therefore, how many pairs of parallel sides are there?
3.Measure the sides of this figure. What can you say about it? Are they equal?

This is an example of irregular quadrilateral.
Describe an irregular  quadrilateral.
