Introduction
Introduction
Welcome to Stage 5 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 is a prime number and how do you know if a number is prime?
How can you quickly find out if 642 824 is divisible by 8?
If three-quarters of a number is 24, what is the number?
What time is it in Mumbai when it is 9 a.m. in Mexico City?
What is a reflex angle?
How do you draw a waffle diagram?
How can a shape be translated?
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.
