Foreword
As the first cohort to embark on the Nine Year Continuous Basic Education at secondary level, we are
pleased to offer you a new series of Grade 7 textbooks. These textbooks have been designed in line
with the National Curriculum Framework (NCF) and syllabi for Grades 7, 8 and 9 − documents that
offer a comprehensive notion of learning and teaching with regard to each subject area. These may be
consulted on the MIE website, www.mie.ac.mu.
This set of textbooks aims at providing a smooth transition from Grade 6 so that learners gradually
get initiated into the requirements of secondary schooling. As per the philosophy propounded by the
NCF, the content and pedagogical approach, as well as the activities, have been crafted to allow for an
incremental and continuous improvement of the learners’ cognitive skills. The content is contextual and
based on the needs of the Mauritian learners. Care has been taken to provide the basics that should
help every student develop key competencies, knowledge, skills, attitudes and values that would make
him or her a successful learner for the grades beyond. The comments and suggestions of a variety of
stakeholders have been kept in mind. We are especially appreciative of those made by educators who
have been part of our validation panels, and whose suggestions emanate from long standing experience
and practice in the field.
The production of this series of textbooks, within a relatively short period of time, has been a challenge
to the writers who have invested a considerable amount of time, effort and energy into the process.
I would therefore wish to thank all those who have been part of the whole process for the time they
devoted to it and their perseverance. The panel coordinators are to be commended for their leadership
and insistence on maintaining the standard and quality of the textbooks, while ensuring that the
objectives of the National Curriculum Framework are translated in the content.
Every endeavor involves a number of dedicated, hardworking and able staff whose contribution
needs to be acknowledged. Professor Vassen Naëck, Head Curriculum Implementation and Textbook
Development and Evaluation, had the very demanding task of ensuring that all panel leaders are
adequately guided with respect to the objectives of the NCF, while ascertaining that the instruction
designs are appropriate for the age group being targeted. I also have to acknowledge the efforts of the
Graphic Artists and the Graphic Unit for putting in much hard work to ensure that MIE publications have
a distinctive quality that singles them out. My thanks go equally to the support staff who have worked
hard to ensure that every one receives the necessary support and work environment that is conducive
to a creative endeavor.
I am thankful to all those who provided the support, both within and outside the MIE, and to the Ministry
of Education, Human Resources, Tertiary Education and Scientific Research for giving us the opportunity
to be part of the whole reform process.

Preface
The ICT panel has taken care to make learning of ICT accessible to all. We have also ensured that students
are empowered with the tools to think critically by accessing an abundance of information in a variety of
forms and by processing them in meaningful ways, to think creatively with the support of various tools,
to solve problem and generate knowledge in an interdisciplinary and collaborative manner thereby
providing them with opportunities to work and communicate with each other.
The workbook has been written with the National Curriculum Framework in mind. It has been designed
to provide the knowledge, practical skills and understanding that students will learn through studying
Information and Communication Technology at Grade 7. The ICT workbook prepares the students with
ICT skills and competencies for the emerging knowledge society, helping them develop capacity to
solve problems in digital environments.
The workbook consist of 8 units which are as follows:
1. Health, Safety and Ethics
2. Computer Operation and Fundamentals
3. Internet
4. Word Processing
5. Spreadsheet
6. Presentation
7. Multimedia
8. Practical Problem Solving and Programming
The workbook is learner oriented and consists of the following:
• Activities in the form of games and practical
• Suggested activities can be done by the teacher to consolidate learning
• Quick test at the end of each topic
• Summative exercise after each unit.
We believe that students should be engaging in practical activities not only one or two terms but
throughout the year along with learning the theory. So we have design a workbook that will allow
students to blend theory and practical.
Throughout the workbook there are a number of colours, boxes and symbols used to facilitate learning.
We have created an avatar named Tipiyu that will be a guide across the workbook.

| Adopt safety precautions when using ICT tools
Computers are safe to use if they are handled properly. It can be potentially dangerous if
misused since they operate using electricity. Learning about safety precautions is important
but adopting them is even more.
Some safety precautions you need to adopt when using ICT tools
•Avoid eating and drinking near computers because you may get an electric shock
if the drink is spilt on a computer.
•Computers use lots of wires and this may cause users to trip over if not well arranged.
•
Do not insert objects in the system unit.
•
Do not overload a power socket as this may cause overheating and even fire.
•
Switch off the computer before connecting or disconnecting any cables.
•Do not open the system unit while the computer is ON because you may get an
electric shock.
•
Don’t switch your computer ON if socket is damaged.
•Make sure your computer is on a strong table as some parts are heavy and can cause
injury if they fall on people.
•Place your computer in a well ventilated space to prevent overheating of the
equipment.
•
Do not try to repair your computer as you are not trained for this.

Application
software
The system software manages and controls the computer whereas the application software
enables the user to do a specific task, such as typing, playing games and so on.
System software is the most important software that runs on a computer. It is a set of programs
that controls the computer hardware and enables the application software to run.
Examples of system software:
•
Operating systems (OS)
Software that acts as an interface between the user and the computer system.
E.g. Microsoft Windows, Android, Linux and Mac OS X.
•
Utility programs
Software designed to help analyse, configure, optimise and maintain the computer.
E.g. Anti-virus software, disk defragmenter and file manager.
Application software refers to programs designed to help the user perform specific tasks,
such as software for video conferencing, creating documents, surf the Internet, playing games
and listening to music.

2.5
| Bits and Bytes
The word bit is a shortening of the words "Binary digIT". The "bi" in binary means two.
A bit can be either 0 or 1. So a bit can be any one of the two values, 0 and 1. The computer
understands binary data, that is, data made up of 0's and 1's. For example, 1011 is a binary data,
so is 1001.
A BYTE is a group of 8 bits.The following are examples of a byte:
•
10110110
•
10010000
•
11111111
COUNTING THE NUMBER
OF BITS AND BYTES
A character, in computing terms, can be a
letter, a number or any other characters.
Even a blank space is a character.
For example:
Each character is represented by one byte
and each byte is made up of 8 bits.
Did you know
Human beings have 10 fingers and we have
been used to counting numbers in group of
tens. Computers, however, operate using the
base-2 number system, also known as the
binary number system.
So computers use binary data, and therefore
use binary digits in place of decimal digits.
Everything you say to a computer is changed to
binary data.
35
Count the number of bit and bytes in the word "Power" below.
First byte
Second byte
Third byte
Fourth byte
Fifth byte
P
O
W
E
R
8 bits for a character
Letter “P” = 8 bits
Letter “O” = 8 bits
Therefore adding the 5 letters
Letter “W” = 8 bits
(5 bytes) from the word power
Letter “E” = 8 bits
gives you 40 bits.
Letter “R” = 8 bits
Quick Test 2.5
How many bytes and bits can you count in the word COMPUTER?
Number of bytes = ........................................... bytes
Number of bits = ........................................... bits
How many bytes are there in the sentences below? Please note that you have to count the
spaces, the full stops and other special characters.
Using computer is fun.
i)
Number of bytes = ........................................... bytes
ii)
12th March 1968 – Mauritius Independence day.
Number of bytes = ........................................... bytes
iii) 50, St. Georges street, Port-Louis.
Number of bytes = ........................................... bytes

3.4 The WWW
The World Wide Web is the most used service on the Internet.
The WWW is the collection of millions and millions of documents called Web pages.
Each web page can be a combination of text, pictures, audio clips, video clips or animations.
Web pages are connected to other Web pages, via hyperlinks.
Going from one web page to another web page, by clicking on a link is called surfing the WWW.
What is a web browser?
A web browser is software that allows access to the Internet and allows you to view web pages.
Examples of web browsers are:
Mozilla Firefox
Google Chrome
Microsoft Internet Explorer / Microsoft Edge

3.5 Uniform Resource Locator
We read earlier that the WWW is the collection of all webpages on the Internet, and to go from
one page to another we click on a link. So how does the browser know which webpage to
display when a link is clicked?
Every webpage on the WWW has an address. This address is called the Uniform Resource
Locator (URL).
For example, the URL of The University of Mauritius is www.uom.ac.mu. This is the address of
the university on the Internet.
When you click on a link the browser gets the URL of the webpage pointed to by the link.
Knowing the address, the browser can fetch and display the webpage requested.
Activity 3
Finding URL of companies
Look at advertisements on newspapers or magazines and
find out the URL of two companies or businesses.

3.6 Search Engines
A search engine allows you to search for information on the Internet. It also has a URL.
A search engine uses what we call keywords in order to look for specific information.
For example, if you want to look for information on the history of Mauritius, the keywords can be:
History of Mauritius
The results sent to the web browser contain web pages, images, videos and other types of files.
Examples of common search engines include:
www.google.mu
www.bing.com
www.yahoo.com

3.9 Electronic Mail (E-Mail)
What is Email?
An Email is an electronic message or mail that you send or receive over a network. To send an
email you will need:
•
A computer or other devices (e.g. tablet, Smartphone) connected a network, eg. the Internet.
•
An email address (e.g. tipiyu@gmail.com)
•
A web browser (e.g. Google Chrome, Internet Explorer, Mozilla Firefox)
Examples of email providers:
Parts of an Email Address:
tipiyu1@gmail.com
User name:
a unique name that
identifies a user.
Domain name:
a company or organization name
that provides the email service.
The @ symbol is read as “at”.
Both the sender and the receiver must have an e-mail address. An e-mail address is associated
with an e-mail account. Every user has a user name or user ID (e.g. tipiyu25) and a password.
The password prevents unauthorized access to the mail.
57
Log into your email provider's website.
For example, if you have a Gmail account, visit mail.google.com.
•You will need to log in with the account you have with that service.
If you don't have an account, you can create one from a variety of free email services.
The user will have to enter his/her
username, following the @ symbol and
email account e.g. tipiyu2@gmail.com
and click on Next.
Then the user needs to
enter his/her password and
click on Next.
Did you know
Remember that passwords
should be a secret known
only to you.

4. Check your "Spam" folder occasionally
Spam email is mainly advertising and scam email messages. These messages are moved to the
Spam folder, where they typically sit for 30 days before being deleted. Check the folder occasionally,
as sometimes legitimate mail may also be found in the Spam folder.
5. Delete or sort read messages
After you read an email and reply to it, you may wish to either sort it into a folder or delete it from
your inbox. This will help keep the Inbox organised and tidy.
6. Don't click any unknown links
Email is one of the most popular ways to trick people into giving out personal information. Never
click links unless you trust the sender. It is best to be cautious, as viruses on the sender's computer
can infect emails.

Learning Objectives
By the end of Unit 4, learners should be able to:
• Adjust properties of images to fit them well within a document.
• Manipulate drawings and shapes.
This Unit will include basic word processing skills learned in previous grades.

4.1 Word Processing
A word processor is a program which is used to create a document. For example if we want
to write an essay, to write a letter or produce a report, a word processor can be used. A word
processor enables someone to create a document, format the document, edit the document
and save it electronically on a disk unlike the old days where typewriters were used.
Format refers to changing the text appearance. For example, using different font style, font
size, text alignment and so on.
Edit refers to changing the content of the document. For example, changing a word or a
sentence.
There are many word processors such as Microsoft Word, Google Docs, OpenOffice, and
LibreOffice.

sweets and cakes. There were also many games and music.
I cut the cake after blowing the candles. Everyone sang the birthday song. Tasty dishes, including
refreshments were served. Everyone enjoyed the party and played games till late at night. Everyone
brought me wonderful gifts and the best gift was from my dad. He gifted me a quad copter. It was really
a nice gift. We really enjoyed the party and had much fun.
How I missed you on that day! You are my best friend, but I understand that you had fever and could not
attend the party. Anyway, I wish you recover very soon.

A cell is the
intersection of a
row and a column
Each column is identified
by a letter
The Microsoft Excel window is similar to the Microsoft Word window. The main differences are
shown in the figure above.

Cell address
Every cell in a spreadsheet has an address given by its column letter followed by its row number.
When you open a blank Excel spreadsheet, it is known as a workbook and each spreadsheet in
a workbook is called a worksheet.

Unit 5 I Spreadsheet
Spreadsheet Activity 4
A spreadsheet contains the following information.
In this part of the activity you do not need a computer.
Write the formulae in the appropriate cell in the above table to calculate
(i) The total marks obtained by each student.
(ii) The average marks for each student. You may use answer from part (i).
Practical Task
For this part of the activity you will need a computer.
1. Open Microsoft Excel.
2. Create a new workbook.
3. Enter the above information in the spreadsheet.
4. Enter the formula for the calculation of total marks in Column E
5. Enter the formula for calculating the average marks in column F.
6. Save the file as myMarkList.xlsx
Excel Functions
Study the spreadsheet. It is used to record the
amount of rainfall at Port-Louis for the months
of January to December.
101
The formula you would write in cell B15 to calculate the total rainfall for the year is
=B2 + B3 + B4 + B5 + B6 + B7 + B8 + B9 + B10 + B11 + B12 + B13
Notice how time consuming it is to write such a long formula.
An easier way would be to use an Excel function to do the same calculation.
A function performs calculations using specific values.
Excel provides functions that can be suitable for quickly finding the sum, average, count,
maximum value, and minimum value for a range of cells.
For Grade 7, you need to know the following functions:
SUM
To find the sum of a set of numbers
AVERAGE
To find the average of a set of numbers
MAXIMUM
To find the maximum value from a set of numbers
MINIMUM
To find the minimum value from a set of numbers
COUNT
To find the number of cells that contain data.
Parts of a function
For a function to work correctly, it must be written in a specific way.
A function starts with the “equal to” symbol. This is followed by the function name.
The range of cells on which the calculation will be done is written inside brackets just after the
function name.
For example, if we want to find the total rainfall for the whole year in the spreadsheet above,
we would write the following
=SUM (B2:B13) in cell B15
To calculate the average rainfall, we just need to use change the function, and we will write
=AVERAGE (B2:B13) in cell B16
Now, write the function you will use to find the maximum and minimum rainfall.
Function to find maximum rainfall (cell B17) ...............................................................
Function to find minimum rainfall (cell B18) ...............................................................

A program which you use
to create other programs.
Understanding
The MS Logo Screen
Turtle’s playground
It is the place where the turtle creates shapes
when you give it commands.
Turtle
It is the triangle or cursor which represents the
turtle in the screen. You can give it commands
to make it create lines and drawings.
Command Box
It is the big space in the Commander window
which keeps a list of what is going on. If you
make a mistake when you write commands,
you will see a message here.
Input Box
It is below the Commander window and it
is here that you type your commands for the
turtle.

Unit 8 I Practical problem solving and programming
Scratch is a free visual programming language developed by the
MIT Media Lab. Scratch can be used to program interactive stories,
games, and animations. It can be downloaded from
https://scratch.mit.edu/scratch2download/
Instead of typing lines of text, as you do with traditional coding, you
drag coloured blocks and join them together to build programs.
Click on Create and
follow Step-by-Step
tutorials to get started
