Paint using a computer
A m
In this lesson you will learn how to perform simple computer
activities through the example of paint.
Bunty: Moz, we want to draw and paint today. Do we double click on one of
these small pictures on the screen?
Moz: Yes, these small pictures on the screen are called icons. Earlier you had seen the icon for music. Now double
click on the Paint icon.
Babli double clicks on the paint icon, points to the
empty space that opens up on the screen and asks
Babli: Is this the place where we draw and paint?
A
Moz: Yes. The blank space in the window is like a paper in
your drawing book where you can draw and paint. This is
called the canvas area. There are also ready pictures
which you can only colour.
Bunty : I see Tools written on the screen. What is meant
by tools?
Moz : When you draw on a paper, you use brushes and
colors. These are your drawing tools. In the same way,
the tools for drawing using a computer can be found
under Tools. A set of tools is called a Tool bar. The
various choices in any tool bar are called the Options.
Moz : Click “Open” under Tools to open a picture. Then
color it by choosing Tools and Colors.
Babli : I want to draw my own picture and then colour it. What
should I click to do this?
Moz: You can do this by selecting the ‘New‛ option under Tools. You can then
use the Paint brush option in the Tool bar to start drawing.
New Screen with Paint option selected. The subset tools of Paint option is
“ Brushes”
Babli: I want to draw 'Sun' in red colour. Should I click on the colour
tool bar?
Moz: Correct. The colour tool bar is called the Colour palette.
Select 'red' colour and the ‘brush‛ tool with which you want to
draw. Then draw on the canvas area.
Colours in the colour palette can be used with many
of the tools. For example, select a ‘yellow‛ colour and then
select the ‘fill‛ tool. Now, click inside the Sun you have drawn,
to fill it with yellow colour.
Bunty: When I click on 'Shape', I see another tool bar with
many shapes. Why is this so?
Moz: What do you have in your pencil box?
Bunty: Pencil, sharpener, eraser, and scale.
Moz: Babli, What do you have in your lunch box?
Babli: Rice, curry and a sweet.
Moz: All the food items are grouped together in the lunch box.
All the writing items are grouped together in a pencil box.
In the same way all the shape items [square, rectangle] are
grouped together in the 'Shapes' tool bar.
Babli [ Pointing to Pentagon]: Pentagon has five sides. I know that.
Moz: Very good. Everything around you has a shape. Can you draw and paint
some of these objects using the tools?
Babli and Bunty use drawing and painting tools and complete the following
two pictures.
Babli: I want to draw
and paint one more
picture. I do not want
to erase this picture.
Moz: Ok. Use the
'Save' option to save
the picture that you have drawn. The computer
saves the picture in a 'file'.
You will learn more about files later.

Corner 1.6
Session I
1. Revise the activities you can do using computer taught in the first lesson. Arouse their
interest by asking them if they want to learn how to draw using a computer.
2. Open the paint program and drawing something. They would be eager to try it on
their own. Now close the program and show the steps to open the program. For
convenience, create a shortcut to Tuxpaint on the desktop. Point out the Tux Paint icon
with the mouse pointer, select it and press enter. Tell them they can also double click on
the icon to start the program.
3. Talk about the canvas area, the colour palette and the tool bar. Explain that the canvas
area is just like the paper we use to draw. The colour palette is the colour dish where they
can dip the brush in the chosen colour.
4. Now show them the open option in the tool bar. A set of pictures would open; select a
picture of their choice and double click to open it. Illustrate how to colour using the magic
option of fill and the colour palette. After colouring, indicate that this has to be saved so
that the picture is not lost. You can associate it with how papers are filed or money is
saved in a piggy bank for later use.
5. Allow the students to practice starting paint program, opening a picture and colouring
it. Let them discover other magic options on their own. Summarize how to start and use
the program. Emphasize the importance of saving what they paint.
Session II
1. Begin the class by revising how to open and colour using paint program. Now focus
on the tool options and teach them how to draw. Point to the tool bar and show them the
pencil, eraser and the line tool.
2. Now just doodle something and erase it. Draw some lines changing the thickness of
the lines and then erase it. You can draw a house, scenery, a clown so that students get
interested and enjoy the class. Repeat 2-3 times, so that they get familiarized with these
options in the tool bar.
3. Summarize the lesson by indicating the tool bar options. In the end stress that drawing
pictures in the computer is not a replacement for drawing with pencil on paper. Some
pictures are easier to draw on paper rather than on a computer!

Lesson
More actions using Paint
A m
In this lesson you will learn some actions common to
many activities.
Babli: Hello Moz, I want to draw a new picture today. Should I click
the 'New' option to get a blank canvas?
Moz: Yes. You can use the New option to get a blank canvas.
You can draw and paint your new picture here.
Babli [after drawing the picture]: You had said that, we
should use the 'Save' option to save the picture in a file.
What is a file?
Moz: A file is like a page in your drawing notebook. Every time you use
a new canvas, the picture will be saved in a new file.
Bunty: I clicked the 'Open' option. It shows many saved pictures. There is
also the picture that I drew last time!
Moz: 'Open' option gives a list of all the saved files. You can continue to
draw and change any of these pictures.
A
Bunty selects the picture that he likes
and adds the line “Happy Birthday' to it.
He uses 'Print' from Tools bar to print
the birthday card.
Bunty: Now when I try to save this
changed picture, will I lose the old one?
Moz: Click on ‘Save‛ and see what happens.
Bunty clicks on ‘Save‛ and sees this screen:
Moz: This is called a dialog box. See here, it asks you how you want to save
the picture. You can choose Yes or No depending on what you want to do.
Moz: It is time for you to go home. You should always close the activities
once you finish working on a computer.
Babli: I clicked on ‘Quit‛ to close the activity. What is this new dialog box?
Moz: You did not ‘Save‛ your picture before you clicked ‘Quit‛. So the
computer gives you a chance to save the picture. If you were just
exploring the options and don‛t want to save the
picture, you can quit without saving.
Shall I tell you one more interesting
