This is the fourth book in our new Middle Years series for international schools (for use with MYP 4, approx. Grade/Year 9).
This book may also be used as a general textbook at about Grade 9 level in schools where students are expected to complete a rigorous course in mathematics.
A URL may be made available so that teachers can preview the content - email hannah@haesemathematics.com.au.
The complete series comprises:
A feature of the accompanying CD is our new ‘self-tutoring’ software where
a teacher’s voice explains each step in every worked example in the book. Click anywhere on
any worked example where you see the
icon to activate the self-tutoring software.
Other features include:

The interactive CD is ideal for independent study.
Students can revisit concepts taught in class and undertake their own revision and practice. The CD also has the text of the book, allowing students to leave the textbook at school and keep the CD at home.
By clicking on the relevant icon, a range of new interactive features can be accessed:
SELF TUTOR is a new exciting feature of this book. The
icon on each worked example denotes an active link on the CD.
Simply ‘click’ on the
(or
anywhere in the example box) to access the worked example, with a
teacher’s voice explaining each step necessary to reach the answer.
Play any line as often as you like. See how the basic processes come alive using movement and colour on the screen.
Ideal for students who have missed lessons or need extra help.
The International Baccalaureate Middle Years Programme focuses teaching and learning through five areas of interaction:
The Areas of Interaction are intended as a focus for developing connections between different subject areas in the curriculum and to promote an understanding of the interrelatedness of different branches of knowledge and the coherence of knowledge as a whole.
In an effort to assist busy teachers, we offer the following printable pages of ideas for projects and investigations:
| Chapter 2: Indices (p. 69) |
Chess board calculations
Approaches to learning/Human ingenuity
|
| Chapter 4: Radicals (surds) (p. 99) |

This book may be used as a general textbook at about 9th Grade (or Year 9) level in classes where students are expected to complete a rigorous course in Mathematics. It is the fourth book in our Middle Years series ‘Mathematics for the International Student’.
In terms of the IB Middle Years Programme (MYP), our series does not pretend to be a definitive course. In response to requests from teachers who use ‘Mathematics for the International Student’ at IB Diploma level, we have endeavoured to interpret their requirements, as expressed to us, for a series that would prepare students for the Mathematics courses at Diploma level. We have developed the series independently of the International Baccalaureate Organization (IBO) in consultation with experienced teachers of IB Mathematics. The text is not endorsed by the IBO.
In regard to this book, it is not our intention that each chapter be worked through in full. Time constraints will not allow for this. Teachers must select exercises carefully, according to the abilities and prior knowledge of their students, to make the most efficient use of time and give as thorough coverage of content as possible.
To avoid producing a book that would be too bulky for students, we have presented these chapters on the CD as printable pages:
The above were selected because the content could be regarded as extension material for most 9th Grade (or Year 9) students.
We understand the emphasis that the IB MYP places on the five Areas of Interaction and in response there are links on the CD to printable pages which offer ideas for projects and investigations to help busy teachers (see p. 5).
Frequent use of the interactive features on the CD should nurture a much deeper understanding and
appreciation of mathematical concepts. The inclusion of our new
software (see p. 4) is intended to help students
who have been absent from classes or who experience difficulty understanding the material.
The book contains many problems to cater for a range of student abilities and interests, and efforts have been made to contextualise problems so that students can see the practical applications of the mathematics they are studying.
We welcome your feedback.
