1. Geometry (objects and drawings)
This book presents the basic skills of Mathematics appropriate for Year 8 students.
The content and order of chapters parallels the content and structure of Mathematics for Year 8 fifth edition, also published by Haese & Harris Publications. Topics are clearly presented in double-page spreads and attention has been paid to sentence length and layout to ensure that the book is easy to read for students.
There is good coverage of core skills and concepts, clear worked examples and well graded exercises.
The book offers a sound foundation in mathematics for students beginning their secondary level education.
By clicking on the CD-link icon, students can access a range of interactive features, including:
The CD is ideal for independent study. Students can revisit concepts taught in class and also discover new ideas for themselves. It is fantastic for demonstrations and simulations. The CD also contains the text of the book – students can leave the textbook at school and keep the CD at home to save carrying a heavy textbook to and from school each day.

We have written this book to provide a basic course in mathematics that Year 8 students will find easy to read and understand.
Our particular aim was to cover the core skills in a clear and readable way, so that every Year 8 student can be given a sound foundation in mathematics that will stand them in good stead whether they proceed to study a formal course or a less academic option in the future.
Attention has been paid to sentence length and page layout to ensure the book is easy to follow. The content and order of the twelve chapters, parallels the content and order of the twelve chapters in Mathematics for Year 8 (fifth edition) also published by Haese & Harris Publications. More difficult investigations and the more complex aspects of mathematics offered in that book, have been omitted.
Throughout this book, there are worked examples, exercises and activities, and with the support of the interactive Student CD, there is plenty of revision and practice.
We hope that this book will help to give students a sound foundation in mathematics as they begin their secondary level education, but we also caution that no single book should be the sole resource for any classroom teacher.
We welcome your feedback.
