Introduction

Welcome to Stage 3 of Mathematics. We hope that this book will show you

how interesting and exciting mathematics can be.

Mathematics is everywhere. Everyone uses mathematics every day. Where

have you noticed mathematics?

Have you ever wondered about any of these questions?

• What can I do to help me make good estimates of quantities?

• What is the complement of a number?

• How are multiplication and division connected?

• What is an equivalent fraction?
• What do ‘kilo’, ‘centi’ and ‘milli’ mean?

• What are area and perimeter? How are they the same?

How are they different?

• How do you read a timetable?

• What is a right angle?

• How can I explain to someone how to get to the park?
• How do you solve a mathematics problem?

You will work like a mathematician to find the answers to

some of these questions. It is good to talk about the

mathematics as you explore, sharing ideas. You will reflect
on what you did and how you did it, and think about

whether you would do the same next time.

You will be able to practise new skills and check how you

are doing and also challenge yourself to find out more.

You will be able to make connections between what seem

to be different areas of mathematics.
We hope you enjoy thinking and working like a mathematician.
