PLEDGE
India is my country. All Indians are my
brothers and sisters.
I love my country, and I am proud of its rich
and varied heritage. I shall always strive to
be worthy of it.
I shall give my parents, teachers and all elders
respect, and treat everyone with courtesy.
To my country and my people, I pledge my
devotion. In their well-being and prosperity
alone lies my happiness.

Foreword
Dear children,
We had been playing some games with the computer
till last year. But, is the computer just a toy? Not at
all. The computer can be used for more serious
matters too. Preparing letters, viewing scenes of the
sky, analyzing mathematical concepts and so on ….
Activities like these are carried out this time. These
are only a few activities from the unlimited
possibilities offered by computers that are
acknowledged as the machines of the era. Try to do
all the activities in this book. Surely it will help you
in learning all subjects
With best wishes,

You might by this time be familiar with the poem
Malayalam written by Vallathol Narayana Menon,
describing the natural beauty of Kerala.
Many pictures might come to your mind when you
recite this poem. Which are they?
 Mountain ranges covered with clouds
 Rivers with dancing waves
 .............................................................
 ............................................................
Can you draw these pictures that come to your
mind?
Many software solutions
are available that help the
computer user to draw
pictures. One such is
KolourPaint.
Let’s try to do this activity using the software
KolourPaint in our computer.
Let’s begin to picturise the description of nature
in the poem.

Figure 1.1 KolourPaint window
When you open KolourPaint, you will see at first
a canvas screen to draw pictures (Figure 1.1). Now,
place the mouse pointer on each tool in the toolbar.
Have you understood what these tools are? The
tools of Tux Paint which you became familiar with
earlier can also be seen in KolourPaint.
Should we use the whole canvas for the picture?
Isn’t it more artistic to draw the picture inside a
particular frame?
from the tool box. Now
Select Rectangle tool
try to click on the canvas and drag it. Don’t you
get a rectangular - shaped frame? (Figure1.2)
Figure 1.2 Drawing a
frame within the canvas
Your picture needs to be saved. Save this to your
class folder with the help of your teacher. Don’t
forget to give the picture a title!
Won’t we lose what
we drew if the
computer
accidentally shuts
down?

Attention please…
When you apply colour, does
it spread over the picture? It
may be because of a small gap
that was formed while drawing.
Previous actions can be
discarded by clicking the Undo

Complete the gap using the

Eclipse Scenes
Let’s read a diary entry written by Vinayan who had witnessed the Solar Eclipse
in 2010.
15 January 2010
Will it become
dark at noon? Will
I see it?
Reached Thiruvananthapuram in the
morning. We waited at the
Kanakakunnu Palace grounds with the
solar telescope and x-ray film
spectacles to view the solar eclipse.
The Solar eclipse began at 11.15 am.
It came to a climax around 1.15pm.
The noon appeared as if it was late
evening. Birds chirped strangely.
The solar eclipse was over by 3 pm.
The experience left an indelible impression on my mind. How wonderfull
is our world!
You would have understood the different types of
solar eclipses from the lesson Celestial Shadow
Sights in your Basic Science text. Have you ever
seen a solar eclipse? Would you like to see an
eclipse?
What kind
of solar eclipse did
Vinayan see?

Games with fraction cards
Prepare twenty fraction cards to begin the game.
Write fractions like 12 , 13 etc.. on ten of these
cards and draw pictures indicating the same
fractions in the remaining ten.
Now shuffle the cards and divide them between the
two players. The first player has to draw a card . If
the other player puts up the equivalent card, he can
have both the cards. If the game advances like this,
the player with more cards will win. You like such
games, don’t you?
Games like these are available in our computers
too. Let’s learn one such game.

notice in my classroom, she wondered.
What sentences can I have in the poster? She
thought.
 I wash my hands before and after I eat

Chapter 6
My Malayalam
Cutting down one tree after the other, he moved to
the last remaining tree to take rest under it. Placing
the axe under that tree he rested there for a while.
The tree gave him shade though it knew it would be
the next target.
Don’t you want to preserve the trees that provide
shade even to the person who cuts it down?
In what ways are trees helpful to us?
What means would you use to spread awareness
among your friends about the importance of
planting and preserving trees?
 Notice

How about preparing a poster too?
“What messages shall we include in the poster?
“acw Hcp hcw” can be a slogan, then.

Chapter 9
Area and Perimeter
Once, a farmer came to see a king. He presented the king with the best of his
harvest. The king was very pleased. He decided to reward the farmer with a
suitable gift. He gave him a 200metre long rope and said, “Stretch this rope
to its maximum in the shape of a rectangle . You are welcome to measure and
take that much land for yourself.”
Can you construct a rectangle with a perimeter of 20 cm?
Did you read the story?
Can you make a
rectangle of 20 cm
perimeter?
How can the farmer acquire the maximum land
using his rope?
Let us help the farmer. Let us use 20 cm instead of
200m for this activity.
Threads of 20cm length are given to all.
If you construct rectangles using threads of 20 cm
each, what would be the perimeter of each
rectangle?

How many rectangles of this kind can be
constructed? Find the length and breadth of these
rectangles. Complete the table. ( Table 9.1)
