Year 9 is an important year for Maths students. The concepts and skills learned in Year 9 are the foundations for the skills for the senior years of high school. Falling behind in Year 9 can make it really hard to catch back up. The Beginner’s Guide to Year 9 Maths is your resource for staying on top.
We wrote the Beginner’s Guide to Year 9 Maths to help students learn and reinforce the core concepts they need to know for Year 9. Each article addresses the NESA syllabus Outcomes for the subject. These can be found here on the NESA website (Stage 5 is what students study in Years 9 & 10).
The Matrix Method for Maths is our proven process to ensure you develop knowledge and skills. | ||
Step | Matrix Method | |
1 | Theory | Developing a thorough understanding of concepts is the first step to mastering Maths. Learn from Matrix Theory Books that are carefully structured to help you understand even the most complex stuff! |
2 | Application | Memorising formulas will only get you so far. Consolidate your understanding by learning how to apply concepts and techniques to solve problems. |
3 | Examples | Work through examples that will actually be in your exam. You’ll learn how to present your solution for maximum marks in exams. |
EXAM SKILLS (50% OF COURSE TIME) | ||
4 | Concept Checks | Learn the most efficient problem solving techniques with different types of exam-style questions. |
5 | Workbook | Practice sharpening your skills with hundreds of exam-style questions. It’s important to keep practising as this is the only way to find the right balance between speed and accuracy. |
6 | Quiz and Feedback | Weekly quizzes and feedback provide you with opportunities to identify your gaps and address them ASAP. |
7 | Topic Test | Working under exam conditions will boost your confidence for the real thing. Learn from your mistakes and fill your gaps so you are continually improving. |
There is a significant jump from Year 8 Maths to Year 9 Maths. Students may find it difficult to apply the concepts they learned in Year 8 to Year 9 because the level of Maths is much harder.
Some common problems that students face are:
For example: Simplify \(\frac{a}{b}+\frac{b}{a}\)
A poor understanding of finding the Lowest Common Denominator would leave students unable to solve this question. In order to successfully solve the question, students must identify that both \(a\) and \(b\) must be in the denominator.
The correct answer would be \(\frac{a^2+b^2}{ab}\)
For example: Simplify \(4^x\times4^y\)
Many students forget that about their index laws where if the bases are the same we add the powers. They make the mistake of multiplying the bases and adding the powers, ending up with the answer \(16^{x+y}\).
The correct answer is actually \(4^{x+y}\)
We’ve learned that many students struggle with Maths in year 9 because they take the wrong approach to learning and study. Here are some of the reasons that students have difficulty:
Now it is time to familiarise yourself with the content of this Guide. This is a resource that you should come back to consistently as you encounter the subjects at school during the year.
First up, we’re going to discuss algebra and algebraic equations.
