Begin the lesson by revising the dos and don’ts the students learned in class I. Ask questions as to why it is important to follow certain rules while using computer.

Introduce the new lesson, by saying that as they continue to use computers they should also learn more rules so that they can remain healthy and safe. Tell the students that anything in excess is not ok. Even if they like to use computer, they should not use it for too long. Discuss the different purposes for which students should use computers.

Emphasize that it is important to ensure safety while using electronic devices. Explain how to handle power cords and be careful while using computers. Show them illustrations in the lesson to identify the correct and incorrect ways of handling computers.

Play out a skit where the actors selected amongst the students bring out right and wrong usage of computer.

Mention the importance of exercises to remain healthy. Students may have already learnt some exercises. Ask them to show some of these exercises. Now highlight the importance of exercises for correct posture, eyes and hands. Explain why it is important to do these exercises if you are a computer user. Demonstrate the exercises in the class with the help of pictures in the lesson. You can even take them out of the classroom to the school ground and practice this exercise!

Summarize the lesson and emphasize that it is important to continue practicing this exercise as long as they continue to use computers.

Begin the lesson by revising the mouse operations that the students already know. Revise what are the left click, right click and double click and their use. Ask students how they should hold the mouse and the correct posture to be maintained while using it. Inform them about the need to be careful.

Start the computer and ask the students to look at the desktop. Make two folders on the desktop and store picture and music files in each of them. Students are already familiar with icons of games, paint and music player. They will note these on the desktop (Ensure that you have icons of these applications on the desktop). Now draw their attention onto the folders on the desktop.

Click on the folder and show them the different files inside the folder. Now copy all the files from the folder and put them on the desktop. Ask them which looks more neat, keeping the files in folder or spreading them on the desktop. After they understand the importance of using a folder, teach them how to create a folder (right click on a blank space on the desktop and select ‘create folder’ option).

The next step is to teach the students how to drag the files from the desktop, into the folder. Put your palm over the student's hand as they use the mouse, and demonstrate how to move the files. After you do this with a few students, ask them to teach their classmates. (drag and drop is a complex activity for some students who may not have the motor dexterity. With time and practice, they should be able to do it. )

Tell the students that they can rearrange the icons, files and folders on the desktop using mouse. Summarize the lesson and emphasize that it is important that they do not hold onto the mouse continuously and with a tight grip. Allow the students topractice these operations.
