About This Book

How To Use This Book

This book is meant to be used for teaching computers to children in the First standard, in a way that is mostly fun (as indicated by the “Masti” in the title). It is designed so that it can be covered comfortably in one year, with one class (30 to 45 minutes) per week. It has evolved from the NCERT framework and is appropriate for ICSE/CBSE schools in India. A week wise schedule of topics is given below.

Interactivity is the key to success with these lessons. In the class, ask the students questions, and let many students answer each question. In the computer lab, if they are doing activities in groups, ensure that they switch “drivers” frequently, so that each student gets to do a fair amount of the activities.

Some of the authors used a preliminary version of this material for teaching at Sri Sri Ravishankar Vidya Mandir (SSRVM) Mulund, Mumbai. As a result of the insights gained, each lesson has a Teacher’s Corner. This section gives a lesson plan, some do’s and don’ts, and other tips, learnt from the above experience.

This book can also be used as a starting point for higher classes. It can be easily adapted for computer-literacy programs. Adults having little exposure to computers can also use this for independent-study.

1. Use of Computers (Weeks 1-4)2. Parts of Computers (Weeks 5-7)3. Do’s and Dont’s with Computers (Weeks 8-10)

One day...When Tejas and Jyoti were playing in their school ground, their

ball rolled into the computer room. Tejas and Jyoti usually stayed back after school, while waiting to go home. They

enjoyed this time, as they had the entire school to themselves. The school allowed children to use the library, playground and other facilities during their free time.

So far, Tejas and Jyoti had not been into the computer room. Today they meekly went in, to search for their ball. To their surprise, they saw a big mouse holding their ball! The mouse was wearing glasses, which were sliding down its nose. It was a funny sight. Tejas and Jyoti got curious. They stretched their hands to take the ball. The mouse moved back playfully and was not at all frightened of the children.

Tejas and Jyoti were distracted by the colourful screens on the computers in the room. They went near one of the computers to have a closer look. Suddenly they heard a voice from atop the computer “Would you like to know about computers?” The children looked up and saw it was the mouse. They were excited to hear the mouse speak. They wanted to make friends with this mouse.

Tejas: I am Tejas, I am 6 years old.Jyoti: I am Jyoti. I am in First Standard. What is your name? How old are you?Mouse: My name is Moz. I am very old.Tejas: Can we be friends?Moz: Yes. I will help you learn about computers and you teach me to play with this ball. Jyoti: Oh! This is going to be fun. Can we play games using computers?

But… it was time for them to go home. Before disappearing with the ball, Moz said, “I will tell you when we meet again, tomorrow. Chin Chinaki!”
