Introduction

Welcome to Stage 4 of Mathematics. We hope this book will show you

how interesting Mathematics can be and make you want to explore and

investigate mathematical ideas.

Mathematics is everywhere. Developing our skills in mathematics makes us

better problem-solvers through understanding how to reason, analyse and

reflect. We use mathematics to understand money and complete practical tasks
like cooking and decorating. It helps us to make good decisions in everyday life.

In this book you will work like a mathematician to find the answers to

questions like these:

• What are negative numbers and when are they used?

• How can you quickly find out if 1435 is in the 25 times table?

• Which is bigger: half a cake or 50 percent of a cake?

• What might you be doing at the time 23:30?

• What shape is a cone?

• What is a dot plot?
• What comes between the points north, east, south and west on a compass?

Talk about the mathematics as you explore and learn. This helps you to

reflect on what you did and refine the mathematical ideas to develop a more

effective approach or solution.
You will be able to practise new skills, 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.
