CAMBRIDGE IGCSE™ AND O LEVEL ADDITIONAL MATHEMATICS: COURSEBOOK
Introduction
This highly illustrated coursebook covers the Cambridge IGCSE TM Additional
Mathematics and O Level syllabuses (0606/4037). The course is aimed at students who
are currently studying or have previously studied Cambridge IGCSE TM Mathematics
(0580/0980) or Cambridge O Level Mathematics (4024).
Where the content in one chapter includes topics that should have already been covered
in previous studies, a prerequisite knowledge section has been provided so that you can
build on your prior knowledge.
‘Discussion’ sections have been included to provide you with the opportunity to discuss
and learn new mathematical concepts with your classmates.
‘Challenge’ questions have been included at the end of most exercises to challenge and
stretch you.
Towards the end of each chapter, there is a summary of the key concepts to help you
consolidate what you have just learnt. This is followed by a ‘Past paper’ questions
section, which contains questions taken from past papers for this syllabus.
A Practice Book is also available in the IGCSE TM Additional Mathematics series, which
offers you further targeted practice. This book closely follows the chapters and topics
of the coursebook, offering additional exercises to help you to consolidate concepts
you have learnt and to assess your learning after each chapter.

How to use this book
How to use this book
Throughout this book, you will notice lots of different features that will help your learning. These are explained below.
THIS SECTION WILL SHOW YOU HOW TO:
ACTIVITY
These set the scene for each chapter, help with
navigation through the Coursebook and indicate
the important concepts in each topic.
Activities give you an opportunity to apply your
understanding of a concept to a practical task.
When activities have answers, you can find these in
the digital version of the Coursebook.
PRE-REQUISITE KNOWLEDGE
This feature shows how your understanding or use
of a topic covered in another area of the book will
help you with the concepts in this chapter.
WORKED EXAMPLE
These boxes show you the step-by-step process to
work through an example question or problem, giving
you the skills to work through questions yourself.
TIP
CLASS DISCUSSION
The information in this feature will help you
complete the exercises, and give you support in
areas that you might find difficult.
At certain points in the chapters you will be given
opportunities to talk about your learning and
understanding of the topic in a small group or
with a partner.
KEY WORDS
REFLECTION
The key vocabulary appears in a box at the
start of each chapter, and is highlighted in the
text when it is first introduced. You will also find
definitions of these words in the Glossary at the
back of this book.
These activities ask you to think about the
approach that you take to your work, and how
you might improve this in the future.
Exercises
Appearing throughout the text, exercises give you
a chance to check that you have understood the
topic you have just read about and practice the
mathematical skills you have learned. You can find
the answers to these questions in the digital version
of the Coursebook.
CHALLENGE QUESTIONS
These exercises will stretch your skills in the topic you
have just learned. You can find the answers to these
questions in the digital version of the Coursebook.
Past paper questions
Questions at the end of each chapter provide a
variety of past paper questions, some of which may
require use of knowledge from previous chapters.
Answers to these questions can be found in the digital
version of the Coursebook.
SUMMARY
There is a summary of key points at the end of
each chapter.
This icon shows you where you should complete
an exercise without using your calculator.

CAMBRIDGE IGCSE™ AND O LEVEL ADDITIONAL MATHEMATICS: COURSEBOOK
How to use this series
This suite of resources supports learners and teachers following the Cambridge
IGCSE™ and O Level Additional Mathematics syllabuses (0606/4037). Up-to-date
metacognition techniques have been incorporated throughout the resources to meet the
changes in the syllabus content and develop a complete understanding of mathematics
for learners. All of the components in the series are designed to work together.

Third edition
Digital Access
The coursebook contains sixteen chapters that together offer
complete coverage of the syllabus. We have worked with NRICH
to provide a variety of project activities, designed to engage
learners and strengthen their problem-solving skills. Each chapter
contains opportunities for formative assessment, differentiation
and peer and self-assessment offering learners the support needed
to make progress. Cambridge Online Mathematics is available
through the digital/print bundle option or on its own without the
print coursebook. Learners can review content digitally, explore
worked examples and test their knowledge with quiz questions
and answers. Teachers benefit from the ability to set tests and
tasks with the added auto-marking functionality and a reporting
dashboard to help track learner progress quickly and easily.
The digital teacher’s resource provides extensive guidance
on how to teach the course, including suggestions for
differentiation, formative assessment and language
support, teaching ideas and PowerPoints. The Teaching
Skills Focus shows teachers how to incorporate a
variety of key pedagogical techniques into teaching,
including differentiation, assessment for learning, and
metacognition. Answers for all components are accessible
to teachers for free on the Cambridge GO platform.
