### What’s new in Year 9 Maths?

Zero and negative number indices will be taught this year. Students will also learn to express numbers in negative and positive powers of 10. Consumer arithmetic will be introduced by calculations involving earning, spending and simple interest. Also introduced this year is application of index laws to simplifying algebraic expressions. Introduction to coordinate geometry involving determination of line gradients and graphs of linear and non-linear equations. In statistics, cumulative frequency and its uses will be introduced. Other new topics in year 9 maths include studying rhombuses, kites and trapeziums as well as measuring composite figures. Trigonometry topics will include finding angles of elevation and depression.

### Main content of Year 9 Maths

The core contents of year 9 maths are:

- Zero index, negative integral indices and the use of index notations for square roots and cube roots,
- The use of scientific notations in expressing large numbers as powers of 10,
- Consumer arithmetic for simple earning, spending and interest calculations with the use of calculators and tables of values,
- Theoretical probability and application of relative frequencies,
- Coordinate geometry involving linear and non-linear relationships,
- Construction and use of cumulative frequency tables and polygons,
- Use of formulae to calculate areas and perimeters of single shapes like rhombuses, trapeziums and composite ones such as quadrants,
- Solving right-angled triangles.

### Common challenges for students in Year 9 Maths

A common challenge this year is the notion of negative numbers. Together with expressing large numbers in powers of 10, some students may initially find it hard to grasp the idea of numbers on the other side of zero or numbers so inordinately large or small that they need scientific notations to record. Another point of difficulty is composite trigonometry.

### Main outcomes for Year 9 Maths

At the end of year 9 maths, students should be able to use index laws to simplify arithmetic expressions, and algebraic expressions as well as expressing very large and small numbers using scientific notations. Furthermore, students should have:

- Learnt theoretical probabilities and relative frequencies
- Be familiar with linear and non-linear relationships and graphs
- Be able to construct cumulative frequency tables and graphs
- Be able to calculate perimeters and areas of quadrilaterals and composite figures
- Apply trigonometry to solve problems involving angles of elevation and depression

### Most important concepts to ensure your child understands in Year 9 Maths

It is important that your child have a good foundation of consumer arithmetic at the end of year 9 maths. Understanding index laws is also important seeing at it is useful for algebraic and arithmetic expressions. Frequency tables are another important concept to ensure your child is familiar with, and of course trigonometry.

The importance of algebra should also be stressed here. Although algebra is not a new topic anymore, its use will be required in a variety of other topics such as geometry and trigonometry. Without knowing how to solve basic equations, for example, your child won’t fare too well in a trigonometry test. This will be a continuing pattern and as such it is absolutely crucial that your child is able to cross-contextualise thier knowledge of numbers and algebra.

### If hiring a tutor, what study habits and content to focus on in Year 9 Maths?

When getting a tutor this year, look out for one who can provide your child not only with ample time and practice questions but also one who can use everyday experiences to explain topics, especially consumer arithmetic and statistics. As maths becomes more complex and abstract, relating to the real world can be challenging but will serve to enhance comprehension and boost interest in the subject.

### Main challenges involved in tutoring a Year 9 Maths student

Year 9 maths presents a considerable shift in the way students perceive numbers. Grasping negative numbers and expressing large and small numbers in scientific notations can pose a big challenge to students this year.

### Some good ideas on how to help your child in Year 9 Maths

Providing everyday problems to help your child learn the concepts in consumer arithmetic, statistics and trigonometry will help a lot. Getting a capable tutor is another way of ensuring your child understand every topic of Year 9 maths.

## What they say about our tutoring:

We chose EzyMath Tutoring as that is the subject our daughter most needed help with, and we decided to pick specialists in this subject over other tutors who seemed to do everything. Our tutor Emma, was a uni student, very professional, friendly, she worked very well with our daughter. Emma had lots of great tricks and tips for Madison to use in her studying and test-taking, broke some things down so they didn't seem so scary or overwhelming to our daughter. Madison was much more confident in math class, homework was easier, she was more confident in taking exams. It meant a lot to Madison and us, a lot less stress at home when it wasn't my husband or I trying to teach her with all the emotions that tend to go along with that. I would recommend EzyMath tutoring to anyone looking to improve their math skills.

Jade has been absolutely wonderful with Lucas. He's enjoying his tutoring sessions and sounding more confident about Maths already. We understand it may take quite a while to see any improvement in his actual marks but there has already been a definite improvement in his attitude towards his capabilities. Lucas is very happy with Jade and we will definitely be continuing the tutoring.

I was very happy with the staff at your head office. My my initial contact person was Marcus, and he was extremely professional and thorough in explaining the services EZY MATHS provide and he reassured me of the the level of tutoring that the company provides and that they will endeavour to match a tutor for my 15 year olds math's concerns. The thing I liked the most is that at no time did I feel pressured and he made it sound so easy; Which it was. Thank you, and I will be using you guys again when the time arises.

We really like Syed and Lucy is working well with him. Her confidence is starting to grow with her times tables which is great to see.

Everything is going well. Lizzy and I are very happy with Michael and pleased with her results so far.

Just letting you know that Layla is gaining a lot from Jacob and in only three weeks. Her confidence is starting to grow little by little and she is trying more on her own which is great to see.

Andrew is very happy with Stephen's tutorials. They have already formed a very healthy teacher student relationship, and Andrew is enjoying his Maths. He got everything correct in a test he did at school last week. The only thing that was incorrect was the fact that his decimal point was not in the correct place.

Natalya is progressing really well with her math tutoring. Daniel is an excellent tutor and Natalya feels very comfortable around him. Her enthusiasm for maths has soared which for Don and I is a big step forward in such a short time. Her teacher has already commented on her progress and we have no doubt that her grades will continue to improve over time.
