Introduction

Welcome to Stage 9 of Mathematics

During your course, you will learn a lot of facts, information and techniques. You will start to think
like a mathematician. This book covers all you need to know for Stage 9.

The curriculum is presented in four content areas:

• Number
• Algebra

• Geometry and measure
• Statistics and probability.

This book has 15 units, each related to one of the four content areas. However, there are no clear

dividing lines between these areas of mathematics; skills learned in one unit are often used in
other units. The book encourages you to understand the concepts that you need to learn, and gives

opportunity for you to practise the necessary skills.

Many of the questions and activities are marked with an icon that indicates that they are designed to
develop certain thinking and working mathematically skills.

There are eight characteristics that you will develop and apply throughout the course:

• Specialising – testing ideas against specific criteria;
• Generalising – recognising wider patterns;

• Conjecturing – forming questions or ideas about mathematics;
• Convincing – presenting evidence to justify or challenge a mathematical

idea;

• Characterising – identifying and describing properties of mathematical
objects;

• Classifying – organising mathematical objects into groups;
• Critiquing – comparing and evaluating ideas for solutions;

• Improving – refining your mathematical ideas to reach more effective

approaches or solutions.
Your teacher can help you develop these skills, and you will also develop your

ability to apply these different strategies.

We hope you will find your learning interesting and enjoyable.
