Teacher’sCornerBook IILesson 7Begin the class by revising what the students already know about writing using acomputer. Create a short cut for text editor application on the desktop. Open text editorand ask the students to note the options, similar to other activities --- new, open andsave. Emphasize that the functions of these options remain same across differentactivities. Revise the function of space bar and enter key to refresh their memory.Remind the students that it is important to save their work by using the save icon.Type a list of words from a topic in another subject. For instance you can write a list ofthe foods we eat --- fruits, dals, pulses and animal products. Now select a word at the topof the list and cut it (using the scissors on the menu bar). As the students note what youdo on the computer, they will wonder where it has gone. Now paste it at the end of thelist. Explain to the students that the computer stores the cut item. When we specify theplace to bring the word, it retrieves the word and pastes it there. You can teach the copyoption, in a similar way.Draw the students’ attention to how the symbols of cut, copy and paste represent theirfunctions. For example, scissors are used to cut and you paste something on a pad, andthere are two sheets one behind the other in copy. This will help them to understand andremember the functions of these options clearly.Summarize the lesson and allow the students to practice. Ask the students to refer thechapter they are learning in science/environmental studies and write 10 importantwords as a list. Tell them to put the words in alphabetical order using the edit --- cut,copy and paste option. Finally, ask them to save the list.Futher Reading m/happy/cutandpaste.html57

Teacher’sCornerBook IILesson 8Begin the lesson by asking the students whether they have observed the teacher/ familymember start a computer. They would mention switching on the buttons, entering someword, following which the desktop is seen. Tell the students that you will now start thecomputer and that they should observe carefully what you do.Switch on the power, CPU and the monitor. (If you are using laptop, inform the studentsthat it has to be charged for use. Demonstrate how the wire is connected and they cannote that the battery is getting charged looking at a particular indicator). Ask them tonote the light on the CPU near the power button. Tell them that pressing the button onCPU starts the computer. Ask the students to note if the monitor has a similar button anda light near it. Switch off this button and demonstrate that monitor is switched off. Nowpress it again to resume working. Tell the students that the switch on the monitor iscalled the toggle switch. (The location of these buttons can vary according to the kind ofcomputer you are using).When the computer is ready, draw the students’ attention to the dialog box. Tell themthat you are entering user name which in turn asks for password. Inform the studentsthat password is the key and it has to be entered correctly. You may use the analogy of apiggy bank and a key to explain username and password. Emphasize that password hasto be kept secret; so that others do not access, delete or misuse your important files.Inform the students that when the computer is not in use, monitor should be switched offto save electricity. You can now teach them how to log off from the computer. Explainthat logging off does not switch off the computer, but allows other users of the computerto use it. Now demonstrate how to switch off the computers. Ask them to note that thelights on the CPU are switched off and only after this the power switch is turned off.Explain why it takes some time to start and shut down a computer. The booting processinvolves checking and starting the system. A similar check is done when the computer isshut down. Note that all activities have to be close before shut down.Summarize the procedure to start the computer and turn it off. Inform the students thatthey should do these operations only under the supervision of their teacher or familymembers.Further Reading :http://en.wikipedia.org/wiki/Logging (computer security)65
